Duplicate Time Machine Backups

I went about 3 weeks without connecting my MBP to my Time Machine drive. Last night when I did it it wasn't seeming to update so I clicked on the "Backup Now" button and went to bed. I woke up this morning to find that Time Machine had created a second full backup of my MBP on the external hard drive. That's fine but what I'm wandering is whether I can blow away the original now (as the external HD is almost full). Seems like I can but I want to be careful.
Also, any idea why this happened? How do you kick off only an incremental backup rather than a brand new full backup?

have you had any hardware changes to your mac? a new logic board perhaps? this would cause a full new backup. also, sometimes waiting too long between backups will cause this too (happened to me once) but I've seen contradictory statements about that. if you don't need old backups simply reformat the TM drive and start backups from scratch. this is by far the easiest way to delete old backups.

Deleting duplicates in iPhoto - Effects on Time Machine Backup

I am new to Time Machine Backup. I have a query, (perhaps a silly one?)
Out of 4500 photos in my iPhoto, I have trashed 300 duplicates.
On my next backup in Time Machine on an Ext HD, will the deleted photos be also gone?
What about the duplicates that I originally stored in my Hard Drive under My Pictures? Are they also stand deleted?

Hi blissalvacion,
Time Machine takes exact copies of your HD at the time the backup occurs. Here's an example:
05/05/10 @ 10:00am - 3500 photos
05/05/10 @ 11:00am - 3300 photos
So at some point in that hour block, you deleted 200 photos. All of sudden at 11:15am National Geographic calls and wants to pay you $1,000,000 for those 200 photos. If you click on the Time Machine icon in the menu bar at the top and select "Enter Time Machine" you can then view your HD as it looked at 10:00am and restore those deleted 200 photos.
The catch, unfortunately, is that with iPhoto the iPhoto Library is a container file (it's really a folder just doesn't look like one). So if the photos were deleted from within iPhoto you'd need to restore the entire iPhoto Library to how it looked at 10:00am. Based on the size of your iPhoto Library, the restore might take a little while.

Duplicate Admin accounts on restoring from Time Machine backup

I need help to remove duplicate accounts, created after restore from Time Machine Backup.
Here is the situation:
1. I was running SL on a Mac Pro with Time Machine backup. I had 5 User Accounts on the Login Window: Shared (Admin account), Dear Wife (DW, also Admin), Kid1 (managed), Kid2 (managed) and Guest (standard), and two 750 GB hard drives, HD1 and HD2.
2. Mac Pro would not boot past the Apple logo with spinning icon.
3. After talking to with Apple Support, it turned out that HD1 had crashed. I took it in to the Genius Bar, where they checked and confirmed HD1 crash and took it in for repair.
4. Apple replaced HD1 and reinstalled SL.
5. I picked up the Mac Pro. At home I reconnected TM and restarted.
6. Upon restart, I clicked on restore from TM backup and there was only 1 TM backup visible to select. After several hours of Transferring Information, about 700 GB was restored
7. Upon finishing restore, I saw the same Login Window as before crash, with the same 5 accounts - Shared, DW, Kid1, Kid2, Guest.
8. Issue: From the Login Window, logging into Shared and clicking on HD1>Users, I now see: Home Icon with Shared1, and four additional folders: Shared, DW, Kid1, Kid2
It seems I now have duplicate Shared accounts in the User folder - Shared1 with the Home icon, and a separate folder with name Shared.
I cannot "Move to Trash" Shared, since I get the message: “Shared” can’t be modified or deleted because it’s required by Mac OS X.
When I go into System Prefs>Accounts: I see My Account: Shared, and Other Accounts: DW, Kid1, Kid2, Guest. After unlocking the accounts, and right clicking on Shared for Advanced Options, I see:
User: "Shared"
-- Account Name: shared
-- Home Directory:/Users/shared1
Question: How do I consolidate or get rid of the duplicate Shared/Shared1 account? I have 350 GB of video/pictures/music in each of these accounts, which is unnecessarily eating up the new HD1.
Any advice would be appreciated. Thanks!

I solved the duplicate account problem.
I had used Setup Assistant to restore from TM Backup and that gave me the duplicate accounts, i.e., method used was:

After carefully reading Pondini's FAQs, I instead used the Restore and install Method, i.e.,
http://web.me.com/pondini/Time_Machine/14.html
No duplicate accounts anymore, problem solved.

How do i restore photo albums from time machine backups without duplicates?

how do i restore photo albums without duplicates from time machine backups? thx

Worth updating? Totally a personal decision. For some it would be. For others it would not?
Upgrading, if there are no problems, does not affect your data. And since bad things do happen you always have a good backup. Especially when doing any upgrade.
Your password question has nothing to do with iPhoto. Try it in the OS forum

I can't clone (Duplicate) my Time Machine backup properly via Disk Utility

I have an ext. HDD Time Machine backup sitting beside my 10.8 MBP.
I want to create an identical ext. HDD Time Machine backup, because it's safe to have 2 identical HDDs backing up my system.
But when I follow this apple guideline, a problem occurs:
Time Machine: How to transfer backups from the current backup drive to a new backup drive
URL: http://support.apple.com/kb/ht5096
The problem is I get a strange path even if I drop "Backups.backupdb" of 3TB1 (The source HDD) onto the root level of 3TB2, the destination HDD (I mean there's nothing in there so I just drag & drop onto the HDD). And the result is my new ext. HDD eating up about 60GB more space.
I have attached pictures of the paths for both Source HDD and Destination HDD, please look.
Why does it alter my file hiearchy like this?
Please help some high-level Mac guy thanks!

Why not just use TM to back up to 2 external drives. TM will alternate between the two when it backs up.
Alternately, you could have a 2 back up strategy like others have using SuperDuper! or Carbon Copy Cloner. Both are excellent 3rd party apps to clone your internal drive(s) and both have schedulers.

Strange time machine backups (duplicate?)

Sorry to cross post this - I posted it initially in 'Time Capsule' by mistake:
http://discussions.apple.com/thread.jspa?threadID=1935448&tstart=0
Thanks

Here's the orignal post from the other thread (since this forum is more on-topic:
I just set up one of the new 1TB Time Capsules and am backing up 3 machines to it. Everything seems to work.
However, my Mac Pro takes FOREVER to back up each time, and a look at the logs shows that its backup up roughly 1GB each time (every hour) that Time Machine runs. This doesn't make any sense because if it's been asleep all night, and I wake it in the morning, it backs up ~1GB. If it's been asleep for a couple of hours during lunch, and I wake it, Time Machine backs up ~1GB once it runs. Even if the system has literally sat idle for the hour between the last Time Machine backup and now, it seems to want to copy ~1GB each and every backup.
Not only that, but it copies almost an identical amount from both drives in the Mac Pro each and every time.

Am I just reading the logs wrong, and this is normal, or does this seem odd to anyone else?
The only thing I'm explicitly excluding from backups is my Parallels directory, which is also the only thing I can think of that would cause such large amounts of data to need to be backed up each and every time. I don't have any filesharing/P2P software installed (another possible culprit).
The Mac Pro backups have been like this since as soon as the initial backup was done - ~1GB for each drive every hour that Time Machine runs for this computer.
If very little is basically changing on my system (at least not hourly) why are these backups so large, and why are they of almost identical amounts from both drives?

Unable to recover Mavericks via Time Machine on iMac (2011). I have one Time Machine backup from this week On new Time Capsule. I already attempted safe boot and NPRAM reset. Hard drive and permissions verified as ok.

Some more history - I'm not too techie so added everything in I thought might be significant!
- Installed Mavericks on iMac in October 2013
- experienced regular low memory issues - used Memory Clean app as a workaround
- last week decided to upgrade installed memory from 4gb to 16gb. Faster loading but still running out of memory - just takes longer to do so.
- also last week purchased 2gb Time Capsule (to back up 660gb on 1TB drive)
- one successful Time Machine backup completed last weekend.
- I decided to try and clear some space, tidy my folders, old music files, delete duplicates etc (Not system files)
- then tried out 'time machine restore' just to test it out. Deleted files and folders recovered ok using Time Machine menu (the one that looks like outta space)
- yesterday, Avast Anti-Virus flagged virus detected (sorry, I didn't manage to capture details) and quarantined file, but I couldn't get any windows to respond so forced Mac to shutdown.
- attempted regular reboot , system hanging on white/ apple symbol screen.
- attempted Safe reboot - reboot stalls at mess 'BootCacheControl: unable to open /var/db/BootCache.playlist no such file or directory.
(I don't know if this is significant)
- attempt NPRAM reset, reboot hanging at Apple symbol still
- attempted reboot into Disk Utility. HD drive verified ok. Permissions checked and Safari permissions fixed (only)
- finally attempting restore from Time Machine Backup via Disk Utility. Stalls at 'select a backup source'. Menu is 'searching for Time Machine Backup....'
Nothing is listed, after a few mins machine just goes to sleep.
My Time Capsule and networks are all switched on. No idea what to try next!

Most of the problems like this that people report on this forum are due to bad "utilities" like Memory Clean and Avast.
Your Mac probably didn't have a virus. There has never been an OSX virus "in the wild". Third party antivirus software is of very dubious utility on Macs. Macs are not PCs. OSX has anti-malware protection built into it already.
Do you have any other third party "utilities" on your Mac, such as CleanMyMac or MacKeeper?
Is the RAM you installed the recommended type of RAM for your Mac?
Take a look at this page: Mac OS X: Gray screen appears during startup
But your OS may be damaged beyond repair, or beyond what disk utility is able to repair.
In that case you have a few options:
There is a small chance that a (reputable) third part utility like Techtool Pro 7 may be able to fix your OS.
Try to boot into single user mode (restart, hold down ⌘S until you see a black screen with white text) and repair your hard drive. Here's a reference with directions: Repair Your Hard Disk in Single User Mode | Everything Macintosh
bite the bullet, boot into the recovery partition or internet recovery, and erase your HD, reinstall Mavericks from scratch, and start over. Your documents are probably still on your Time Machine Backup. I wouldn't reinstall the documents via a migration- you don't want to reinstall bad system files along with your documents- but you could copy them one by one back to your internal HD. And most importantly- don't reinstall any third party "utilites" like Memory Clean or Avast (or any other third-party antivirus software, for that matter).

Time Machine backup and main drive corrupted. Help! (REWARD OFFERED)

Here's the deal:
I have a Macbook Pro and a Mac Mini both runnign Snow Leopard. I use the Mac Mini as a kind of media center / server, it has a few external drives connected to it. On of these drives (1GB) is dedicated to Time Machine, the Mac Mini (80 GB hard drive) backs up to it directly and the Macbook Pro (500 GB hard drive) does it over the network (Time Machine created a sparsebundle). This has worked well for years now. Occasionally I got the error that Time Machine needed to start a new backup because the old one was corrupt. That happened about 2-3 times a year (did the same thing when I backued up via USB). Now about 2 weeks ago, that error came up and I just let the Macbook Pro on overnight and connected the ethernet cable for faster transfer.
When I woke up, the Macbook Pro didn't respont at all, spinning beachball, no response at all beside mouse movement. I let it do it's thing for another 10 hours (while I was at work) and just held down the power button to power off and restart it. But all I got was the gray-on-gray flashing folder with the question mark in it, that's what you get when the Mac can't find bootable partitions. So I popped in the OSX Snow Leopard install disk, ran disk utility. It saw the hard drive, but no partition (i.e. Machintosh HD) on it. I checked the Time Machine backup and the sparsebundle was 300 GB (the Macbook Pro had 400 GB used, the remaining 100 GB were free). There is no way to restore from an unfinished Time Machine backup...
First thing I did was clone the internal (Macbook Pro) hard drive to a DMG disk image using DiskDrill (the only program I found that could recognize the drive at all, not even DiskWarrior could). I also bought the exact same hard drive model and partitioned it like the cloned the corrupted hard drive to the new one using ddrescue (a command line tool that doesn't quit upon i/o errors but proceeds and tries to recover as much as it can). It copied everything except 65 kilobytes, the corrupted drive seemed to be physically damaged in a bunch of sectors relatively at the beginning of the disk. Since I had now an exact copy on a fresh, healthy drive, I went crazy trying out Disk Warrior (didn't recognize the drive at all), data rescue, testdisc, p a Windows isk, etc. Only R-Studio (on windows) showed the EFI and Macintosh HD partitions on there, they started and ended on the same sectors on the corrupted drive and its clone. After some research, I figured that the partition table was corrupt so I reformated the clone disk using the OSX Snow Leopard install disk (1 HFS Journaled Partition with GUID Partition table). R-Studio showed the EFI and Macintosh HD on that reformated drive, again, same sectors as before. So I figured I could just copy just the bytes where the Macintosh HD starts from the corrupted drive to the clone (using ddrescue). That worked, after almost 24 hours, I had the clone drive with a "disk1" partition on it that even disk utility could see.
Now I was able to run Disk Warrior on it, but all it could do was recover a few Application folders (Resource-Folders and lproj-stuff), about 100 MB in total. It couldn't repair more of catalog file apparently. Luckily, Time Machine backed up quite a bit (300 GB out of 400 GB of data) and I was able to manually copy all the Dokuments, Desktop, user Library, Applications, Music, Download and Movies. Unfortunatley, only a little bit of the Pictures folder was copied. iPhoto library (80 to 100 GB) was nowhere to be found, backup must have failed right then. I can salvage the drives (time machine drive, original hard drive with a few broken sectors, DMG-image of that drive, 1-1 copy of that drive with partition table repaired) but that only gives me files with numeric names and today's date on teh JPEGs (instead of the date the picture was taken).
Is there any way I can recover that iPhoto library? It appears the catalog file got corrupted because the hard drive (only 8 months old...) failed on a few sectors. If I understand it correctly, the catalog file on HFS+ file systems is where the folder structure and file names are stored in a B-Tree. I can't imagine that some i/o error during backup can totally annihilate that file when it was working perfectly before. Here's a few things I want to try out but haven't figured out how so far:
- Time Machine had to start a new backup. There's plenty of free space on that drive so there's a good chance there's old data left on it. Is there a way to restore files (including file names) and fodlers from deleted time machine backups?
- Is there any way to re-build that catalog file from what is there left on the original hard drive? I can't imagine 65 kilobytes destroys it all.
- Are there other ways to recover my iPhoto Library? The raw JPEG (and AVI) files with correct file names or metadata would suffice.
Thanks in advance for any help, I'll actually reward the person with a working solution, 5 years of photo memories are somewhat important. It really ***** that a failure during a backup destroys that...

Final Update:
The catalog file on the original hard drive could not be fixed. Seems like Mac OSX tried to repair the catalog file while the sectors this file resides on failed. To make things worse the partition table was also broken beyond repair, even overwriting the sectors with a new correct partition table didn't help. DiskWarrior found less then 100 MB worth of stuff, mainly Applications folders.
I recovered pretty much everything from the incomplete Time Machine backup by right-clicking the sparsebundle and browsing through the folders with the long alphanumeric names, looking for the version of the folder with the most files in there. All I was missing was part of the ~/Pictures folder, i.e. photobooth pictures and the whole iPhoto Library. My best option was to recover these files using data recovery tools.
DiskDrill proved to be the absolute best, fast, responsive, efficient, and the only one able to mount the DMG-file with no valid file system on it. As there were many i/o errors and broken sectors on the original hard drive, I made a copy of it using a free command line tool called ddrescue (the standard dd tool just aborted when it encountered the i/o error). ddrescue copied the whole drive to a DMG image, I had 56 kilobytes with errors on the first pass, but it managed to shrink that down to just 4 kilobytes (wow!) after the second pass where it tries to re-read the broken secors. It took about 24 hours for a 512 GB 2.5" drive (5400 rpm) but well worth it. Be advised that ddrescue is really persistent and tries everything to recover those last errorneous bytes. At the very end of the process, the read/write head of the hard drive just goes wild trying to catch the data on the sectors with different momentum. This works but I assume this is pretty damaging for the original drive. I also copied it all to a new hard drive (again using ddrescue) and tried partition and catalog repair tools on that (DiskWarrion, testdiks, pdisk, etc.). Still no hint of a good result.
I made a deep scan on the clone hard drive with DiskDrill. At the end (after about 8 hours over USB) it found 13 partition (I assume that's the Macintosh HD, EFI and some DMG files lying around) and hundreds of thousands of pictures. I restored some JPG files just to check the quality, some were damaged, some were good with all the EXIF data intact. I just made it copy all JPG files into a folder. I know the pictures taken from my camera produce JPGs larger than 1 MB and smaller than 5 MB, so I sorted them by size and moved the smaller and larger files into seperate folders. I took the remaining folder (100 GB) and just dragged it into iPhoto. It imported them overnight. Auto-Split by events and I got my library back, alas with different file names, originals and edited versions side by side, lots of duplicates, some damaged, some not. But hey, all the pictures in chronological order. Okay there was also one large event with all the JPGs without valid EXIF data landed inside, iPhoto just takes the file creation date (i.e. the date where the recovered file was copied). As far as I can tell, these are all just data corpses, halfway overwritten copies, random pictures from the internet, desktop pictures, etc.
I started to work my way back through the events, deleting the duplicates and renaming the events. There's an app called "Duplicate Annihilator" which apparently can find duplicate pictures in iPhoto and mark them for you. The free version only does 500 pictures but if it works, I'll get the full version. It can mark th eduplicate photos by adding something to the picture comment in iPhoto so you can manually review it all. Good stuff!

Concerns ALL Time Machine Users. HOW TO MOVE Time Machine backups. Help !

Concerns ALL Time Machine Users :
MOVE (or COPY) Time Machine backups from a "x"To Disk to an "y"To greater disk.
Hello and thank you all for reading me,
First, excuse me if I make language errors (I'm French).
Secundo, I don't know if you'll find something interesting for you
in what I write about Time Machine and my own problems,
but there's a possibility also that YOU could perhaps help me.
I'm talking about Time Machine and his **** Backups.backupdb folder,
containing "*Name of your Mac*" folder,
this folder containing Time Machine backups, format : YYYY-MM-DD-HHMMSS
Time Machine doesn't recognize the backups it made *IF YOU MOVE THEM*.
I have perhaps a solution in this message.
You'll see below what kind of problem I (and you could) have.
Since 12/01/10, an Apple Adviser Level Two (and me)
are trying to understand how to move backups from TM1To Disk to, let's say, a bigger one.
My case is TM1,5To.
*Purpose :* Move 19 backups from Time Machine X disk to Time Machine Y disk.
Delete TMX disk Time Machine backups after that.
Make TMY disk the current used Time Machine Disk.
I don't remember exactly what we did before
(we even created a "root" account with password (dangerous to do),
but it didn't solve the problem),
but we finally copied :
TM1To > Backups.backupdb > *MacBook Pro* folder (containing 19 backups) into :
TM1,5To > Backups.backupdb folder.
The Copy application announced *16 hours !* (without antivirus, to remove absolutely).
So I said goodbye and thank you to my Apple Adviser. After *8 hours*, Copy failed.
BUT it had succeeded to copy *4 backups ONLY* (why ?) in TM1,5To.
I immediately verified and checked each of these with Get Info.
They had EXACTLY the same size (Byte to Byte) as in TM1To.
➔ BUT HERE IS MY OBSERVATION :
After designing TM1,5To as Time Machine Disk, I ordered it to Backup (now).
And what did Time Machine do in TM1,5To > Backups.backupdb ?
It created a *NEW folder*, named *MacBook Pro 2* !
➔ *I HAVE NO ACCESS* to TM1,5To > Backups.backupdb > *MacBook Pro* (4 backups copied from TM1To, remember) ;
➔ while I still *HAVE ACCESS* to TM1To > Backups.backupdb > *MacBook Pro* (19 backups) ;
➔ *AND I HAVE ACCESS* to TM1,5To > Backups.backupdb > *MacBook Pro 2*,
where Time Machine makes actually his backups.
*NOTE :* If you *change the name* of your computer,
Time Machine *changes automatically the name* of the folder who is in Backups.backupdb folder.
➔ ① I have *never seen* such protections (Sharing and Permissions).
You are not allowed to do anything. I've tried to change permissions,
first : "R+W", after that : "Make (Me) the owner", I can tell you : DON'T DO IT !
➔ ② It's impossible to install an OS on a Time Machine disk
(I thought it would allow better permissions).
OS Installer detects the existence of a Backups.backupdb folder
and refuses to install on this disk or partition.
I have now the bad intent to install minimal OS X
1) after deleting (how ?) this folder (but not its contents, how to move it ?)
and 2) declare *after that* the disk as Time Machine disk.
➔ ③ Time Machine doesn't backup OTHER Time Machine backups
(who are in an ancient-not-choosed-for-backups Time Machine disk) NOR backups this disk
(detects, once again, the existence of a Backups.backupdb folder).
AND you can't *absolutely not remove backups from the folder the're in*
(for me, *MacBook Pro* or *MacBook Pro 2*).
➔ ④ I didn't have time to do it, but I think there would perhaps be a solution
in restoring backups in partitions specially created to receive them (having the same name,
that sort of thing) and then re-backup these partitions (vicious and complicated).
There is a function on Mac OS X Install DVD : start with it, and then (do not install)
choose "*restore from Time Machine backup*" from the menu bar (it's called "Utilities", I believe).
➔ ⑤ I *absolutely don't understand* what follows :
— If I add (in my TM1To disk) the bytes of the 19 backups
in Backups.backupdb > *MacBook Pro* folder, I obtain about *1,8 To*.
— It's impossible (and not french).
— When I check the size used with Disk Utility (NOT with Get Info),
I find a correct (?) size : *about 750 Go*.
— What are Time Machine backups made of ?
It can't be aliases (because of their size, and because *aliases suppose originals,
and where could they be ?*), or am I wrong and becoming crazy ?
➔ ⑥ If you refer to the numbers shown at the end of this text (*4 backups*),
you'll see I could *delete duplicate elements* inside these 4 backups,
to win space (but *what kind* of space *if I delete aliases* ?).
Back-In-Time (see below) says he does it.
BUT is it really the OLDEST items I have to destroy (see ⑤),
when I don't know with what kind of ARTEFACT I'm acting ?
What does Time Machine delete to create more backup space ?
Is it REALLY the OLDEST backups it treats, or duplicates, OR ?
*What you can do :*
Find and go to Tri-Edre.fr or Tri-Edre.com/fr site (it's a french company
that creates small Mac applications since fifteen years at least,
I think I already bought them several programs in 1990) ;
Their program *Back-In-Time 1.4.4* is free (Trial) and complete to download (with PDF docs too).
It is *ENTIRELY DEDICATED* to Time Machine and *things you can't do* with.
Price is about 30 €, I think it's worth.
The TRIAL version you will obtain can only work on the LAST Time Machine backup,
but you will see what's featured *AND :*

I hope those remarks to be useful for somebody, tell me if it has helped.
I will also publish this in any Time Machine topics I find here, and in MacRumors site too.

Perhaps if I used a specific Copy software, it could work ?

(you will think I'm crazy).
With my kind regards, and good luck if you have other Time Machine problems !

Dear James Pond,
Thank you once again, and, don't be afraid, I will be as short as possible,
but I need to use your last reply (I've cut all what was already said).
JP ➔ You can copy an entire set of backups, but you cannot copy part of it successfully. See #18 etc.
JP ➔ Read this from the first paragraph: "you cannot copy only selected backups,
or merge two (or more) sets of backups." The structure of the backups simply will not allow it.
I've read it, and found it regrettable. And I've also read, after that, what were the solutions under Leopard and Snow Leopard, and my conclusion is that it's a *dead end* for me. In short,
— I can't move (by drag and drop) the 1To's Backups.backupdb folder (containing MacBook Pro, 19 backups, access) to 1,5To, because there exists already the Backups.backupdb folder created by copy on 12/01 with Apple Assistance (containing [MacBook Pro, 4 backups of 19, no access] and [MacBook Pro 2, 15 backups, access]). I don't even know if it could be deleted by the copy (and I don't wanna do that anyway) ;
— I can't rename (and what for, I already forgot it) any Backups.backupdb folder nor delete it ;
— I can't copy any Computer'sName folder (entire set containing backups), being in a Backups.backup.db folder, into another Backups.backupdb folder ;
— I can't copy any (or all of an entire set) YYYY-MM-DD-HHMMSS backup(s), being in a Computer'sName folder, into another Computer'sName folder (even if it would be empty).
— Saying NONE in Time Machine Preferences and putting it to OFF is simply no use.
All is said. What I can try to do is :
— Delete (not with Finder, but with Back-In-Time) all duplicate things I find in all backups and also entire duplicate backups (I have full access to all with the software) ;
— Restore each of the reduced-to-minimum backups obtained in specially right-sized partitions wearing the YYYY-MM-DD-HHMMSS name of each restored backup. Time Machine doesn't backup his backups, but will backup these partitions.
I'm afraid to be actually completely running out of the target, when I read what I write … It's time to go to bed !
Reminder (OH) : Where did you find these amazing informations ?
JP➔ Some of it is detailed here: http://www.appleinsider.com/articles/07/10/12/roadto_maco[]sx_leopard_timemachine.html
➤ Thank you ;
JP➔ and here:
http://arstechnica.com/apple/reviews/2007/10/mac-os-x-10-5.ars/14
➤ Thank you too ;
JP➔ You have to understand the structure. When TM does the first backup, yes, it copies everything.
On subsequent backups, it copies what's new or changed, but also makes "hard links" (sort of like aliases) to the copies of the things that didn't change. That's how it can only back up a few things each time, but show you a complete "snapshot" of the way your entire system looked at the time of every backup.
➤ I'll do my best to understand.
JP➔ Time Machine deletes backups under two conditions. See the first part of #12 in the Frequently Asked Questions User Tip, also at the top of this forum.
Under normal circumstances, you should not have to delete any backups. See the rest of #12.
➤ I understood why Time Machine didn't delete oldest backups : they were not weeklies ones.
Reminder (OH) : How can I destroy the (corrupted ?) not working "2010-01-27-164345.inProgress" in 1,5 To, which causes Time Machine to abort any backup of any size I ask ?
JP➔ Why do you think it's corrupted? TM is designed to "recover" a partial backup.
➤ I'll verify that with the little Tools/Apps I discovered in your FAQ User Tip document and downloaded immediately.
Why didn't Apple tell me anything ? It's my fault, I'm perhaps not clear and not demanding enough more from them.
JP➔ You cannot install OSX on a disk containing TM backups. That's because they need to be on separate disks.
Technically, you could put them on separate partitions of the same disk, but that would not be a good idea.
➤ I never told you that (there would be no interest at all). I talked about the same location, to see if it would allow me more permissions, but if all works without doing it, it's really no use.
JP➔ Sorry, I don't know what that means.
➤ I'm sorry, I didn't explain : "but if all works" meant : Copy Backups.backupdb, "without doing it" meant : Install OSX.
➤ If I install an OSX BEFORE, Time Machine will REFUSE completely to backup on it, it's understood.
JP➔ Correct. The partition you're running from will not be an option in TM Preferences > Select Disk. That prevents TM from backing-up it's own backups!
➤ Would it be so absurd ? Maybe it could resolve my actual problem ?
I think you are right, but I don't know why. I trust you.
Reminder (OH) : "I will not bore you again except if I don't find a specific answer to an unknown-never-seen-incredible malfuction."
JP➔ Don't worry about that -- thats what this forum is for, especially if you're still having problems.
➤ It's seems in fact that there is no possible solution, except what I said above and is certainly crazy/out of subject.
Just try to be as clear and concise as you can.
And please don't post the same things repeatedly -- it wastes your time and ours, and can confuse other folks.
➤ You're absolutely right and I tried to do so this time, and I'm sorry because I see it's still (far) not enough (short).
Thank you once more. I wish you a good evening and week-end. Here it's 01:40 AM.

Is there a way to copy a time machine backup to a second drive?

I'm in a foreign country and someone wants to buy my laptop, for a price where I can upgrade to the newest model, and have some $$ left over. I have an external drive at home with a time machine backup I did right before I left, but that's it. What if I have someone at home buy a new drive? If they copy all the data on my existing backup drive, will the time machine backups copy and be useable to set up a new laptop? If not, could they use the disk utility on another mac to duplicate my current time machine backup, and would that second mac need to be running 10.5 Leopard? Would also appreciate any advice about how to create another back up using dvd's. I probably can't get another external drive to make another backup to bring with me. I have internet so I can send the latest data from my trip to my idisk. My goal is to have two, independent backups, so if something happens to one, I can still set up a new machine. Also, how can I securely erase my data and programs? Thanks!

Yes, but only if it's done using the procedure in item #18 of the Frequently Asked Questions *User Tip* at the top of this forum, or SuperDuper!. Otherwise they won't be copied properly and won't work.
Would also appreciate any advice about how to create another back up using dvd's. I probably can't get another external drive to make another backup to bring with me.
If you have much data, DVDs aren't going to work well. But if the main things in your home folder aren't too large, just copy them to DVDs. If there's more than will fit a single DVD, divide it up so you can put, say, documents on one and photos on another.
Can you get a portable external? They tend not to be lighting fast, but for your purposes, might be sufficient.

Initial Time Machine backup 60 GB smaller than HD content?

Hello,
I've just performed an initial backup with TIme Machine on an external HD. The result is that TM's backup's size is 360 GB, but my internal HD that has 420 GB of data...
I had no problems during the backup, no warning messages. I don't understand, so I'm not very confortable pursuing with this backup.
The only explanation could be that I've a lot of duplicates on my iMac (2x big iTunes library with same files...) at the moment: does TM save only one copy of same files that are in different directories of the source HD?
Thanks :)

You can verify your Time Machine backup.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy – do not type – the following line into the Terminal window, then press return:
sudo tmutil compare
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
Files that you’ve excluded from backup, or that are excluded automatically, are ignored.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.

HT201250 Time Machine backup disk not found

I recently reconfigured my external disks, creating a 500GB oartition for Time Machine backup. thefirst time I set up Time machine to use that partition all went well. Seconed time it failed "cannot find backup disk."
This is a 24 inch, mid 2007 iMac OS X 10.8.2. I am using two external backup drives - 1T LaCie with 4 partitions and a BlackX removable adaptor with a WD 1T drive plugged in. Both are formatted Mac OS Extended (Journaled) In the view below the top "Time Machine" drive at the top is a duplicate of the last drive in the list.
If I select the top drive - I have the option to "Remove Disk" - NOT to "Use this Disk." So I have to select the bottom "Time Machine" drive. The backup will then run once but on the second try I get "Time Machine couldn't complete the backup to "Time Machine". Unable to complete backup. An error occured while creating backup folder." Whether I remove the top listed disk or not doesn't seem to matter, sometimes it finds the drive, sometimes not!
The BlackX is a USB connected directly to the iMac. The other partition on that drive contains movie clips and they run fine.
There is a backup folder on the Time Machine drive with six backups - however I have to "reset" the Time Machine each time to get it to backup. It craps out on the second try every time. Got me buffaloed! Any ideas?

Assuming you have nothing on your Time Machine volume that you need, erase that volume and Verify it from Disk Utilities. Repair if necessary. Then, go into the Time Machine Preferences and Remove the selected drive to use. Now, reselect it and try a backup.

How to restore time machine backup without disturbing already installed app

Hi!
My school recently reconfigured/reformatted my macbook and install the school image. Now it is filled with applications that the school help us installed. Now how do i restore the backup that my time machine backups last time? Migration assistant or what? I did not change my mac, it is just that my hard disk got reconfigured. How do i restore backup without disturbing the apps my school installs?
Please help thanks!
ALa.

I'm not sure what you mean by that. Is your user account still there?
If not, and if you have either Time Machine backups or a "clone" as backups, yes, use Migration Assistant. See [Using Migration Assistant|http://web.me.com/pondini/AppleTips/Migrate.html]. Note that you must be logged-on with a user account that's named differently from any of the accounts you want to transfer, or else be prepared to rename the duplicate.
If your backups aren't either Time Machine backups or a "clone," you'll have to drag and drop or restore using the app that made them.

Restore Time Machine backup to newly-formatted Macintosh HD

I recently had to erase and re-format my internal start-up drive ("Macintosh HD," formatted GUID Partition Table) while troubleshooting. Turned out it was a failed main logic board, display and display LED backligh, so it was in the Apple Store for 2-3 weeks (long story). I have my Time Machine backups on an external 2TB USB drive, which has its own system, and is bootable. The newest Time Machine backup I have is from 11/13/11, but I thought I'd be safe and do a belt and braces backup, so I used Carbon Copy Cloner to backup Macintosh HD to a disk image. Somehow, I royally screwed it up, and I have THREE CCCloner backups on my 2TB drive (as well as the Time Machine backups). The three CCCloner backups are:
2011-10-26 (October 26) 15-52-21, total 14.18 GB (no System or Users folders)
2011-11-13 (November 13) 21-47-17, total 16.86 GB (System folder = 136.1 MB; Users folder = 1.54 GB)
2011-11-20 (November 20) 18-58-00, total 12.84 GB (System folder = 27.6 MB; Users folder = 1.05 GB)
It would seem I somehow invoked an incremental backup in CCCloner, and I do manual Time Machine backups.
The problem here is two-fold:
1. Between 11/13/11 (last Time Machine backup) and 11/20/11 (last CCCloner backup), I did a LOT of work, that I don't want to lose, but I don't know how to reconcile the three CCCloner backups. I've been in communication with the developer of CCC, but apparently he's taken the weekend off, and we have not yet worked out a way to cleanly reconcile the three CCCloner backups, which is what I would MOST like to do, as it contains the whole week's work between 11/13/11 and 11/20/11.
2. When I erased and reformatted my startup Macintosh HD, I, of course, severed any link between it and the Time Machine backups on the 2TB USB drive.
I suppose the quick and dirty way to get back to my Macintosh HD status is to do the following (found in an Apple Support Archived document):
"Once the drive has been formatted, quit Disk Utility to return to the installer. Go back to the "Utilities" menu again, and choose "Restore From a Time Machine Backup." Connect your Time Machine backup drive, and allow it to be scanned for valid backups. Choose your latest backup from the list provided, choose the destination for the restoration (the newly formatted "Macintosh HD"), then let it do its thing."
Then cherry-pick the new-to-11/20/11 items out of the CCCloner folders. Not an elegant solution, but I can't think of any other. I don't mind reformatting the Macintosh HD again, but then having to pick through the CCCloner dustbin is a big PITA
Anyone have any ideas?
Bart

Nope to both.

Individual folder "Get infos."

<< May I ask why, with an iMac, you're doing all your backups manually, rather than letting at least some of them, especially Time Machine, run automatically? >>
The discussion below with Mike Bombich, of CCC, to which I replied just a couple minutes ago, may help explain some things (it will NOT explain my stupidity -- my only excuse is that I was pressed for time after a long and pointless search in all the wrong places for a very severe problem I was having, as you'll see). Why I didn't do a Time Machine backup just before I took my iMac in for service is a question I can only answer by saying "Duhhhh..."

Hi Bart:
<blockquote>Choosing the "2TB" drive as the "source" in CCCloner would give me the actual, bootable 2TB's system, which has few, if any, of the permissions, settings, etc. that were part of the the original Macintosh HD System files, which is what I'm trying to recover.</blockquote>
Unless you backed up another system to the 2TB volume since November 20, then that volume definitely has everything from your Macintosh HD as of Nov 20. You ran this task at that time:
2011-11-20 18:57:58 -0500
Task: Copying selected files (-psn_0_106522)
Source: Macintosh HD
Mount point: /
Destination: 2TB
Destination path: /Volumes/2TB
Settings
Archive deleted items, owner: bartonbrown
Archive modified items
Do not automatically prune archives
Which means that everything from your Macintosh HD volume was copied to the 2TB volume, and anything that was already on the 2TB volume was moved aside to the _CCC Archives folder. With the exception of the presence of the _CCC Archives folder, the 2TB volume was an *exact* replica of your Macintosh HD volume when that backup task finished on Nov 20.
I think this actually means that the restore process should be really easy. CCC won't copy the contents of the _CCC Archives folder (unless you choose it as a source folder explicitly), so if you choose the 2TB volume as the source and Macintosh HD as the destination, your Macintosh HD volume should be back to the state it was in on Nov 20. I don't see any need to exclude anything from the restore -- anything that wasn't on the Macintosh HD volume was moved to the _CCC Archives folder.
As an aside, you aren't going to find the bulk of your (most recent) Macintosh HD items in the _CCC Archives folder, that folder contains items that were on the 2TB volume when you started that backup task (which means there probably are some pretty important items in the _CCC Archives/2011-11-20 (November 20) 18-58-00 folder). You will find some items from Macintosh HD in there, but they're older versions of files from previous backups, and items that you have since deleted from Macintosh HD.
<blockquote>is there any way to back up onto an already bootable drive with CCCloner and STILL be able to choose the INDIVIDUAL CCC backup I want to restore the Macintosh HD drive.</blockquote>
Yes:
1. Create a new folder at the root level of the destination volume (e.g. "Macintosh HD 12-03-11")
2. Choose "Macintosh HD" from the Source menu
3. Choose "Choose a folder..." from the Destination menu and select the new folder that you created on the destination
When you want to restore from that, you'd boot from the 2TB volume, then in CCC choose "Choose a folder" from the Source menu and select that folder as the source.
You could also choose the "Create a new disk image" option, but I personally prefer backing up to a folder if the destination volume is formatted as HFS+.
Lastly, one thing to keep in mind with either of these solutions is that subsequent backups directly to the 2TB volume (with default settings) will cause the unique backup folder on the destination to be archived. You can avoid that by using CCC's "Protect root-level items on the destination" option. That's the setup I alluded to earlier, in the "I want to back up my startup disk and a data volume to the same backup disk" article.

Hi Mike --
"Unless you backed up another system to the 2TB volume since November 20, then that volume definitely has everything from your Macintosh HD as of Nov 20 ...and anything that was already on the 2TB volume was moved aside to the _CCC Archives folder. With the exception of the presence of the _CCC Archives folder, the 2TB volume was an *exact* replica of your Macintosh HD volume when that backup task finished on Nov 20.
Oddly enough, it wasn't: for one example, the Time Machine backups, which were NEVER on the Macintosh HD volume, are still on the 2TB backup volume, untouched, and so are literally thousands of files and folders I had backed up directly to the 2TB backup volume -- and thousands more I'm pretty sure weren't -- that DIDN'T end up in the _CCC Archives folder, but at the root level of the 2TB volume.
I wish I'd done a window grab of the 2TB backup volume's window before I did my 11/20/11 backup, and before I restored Macintosh HD from Time Machine, but I was so caught up in testing -- 60 hours worth, and all to no purpose -- for what a senior advisor fromr a company whose name is associated with the pomaceous fruit of the species M. domestica (genus Malus, family Rosaceae) was positive was a problem with third-party memory, just before we finally set up the FOURTH Malus domestica store appointment and I had to bundle the iMac up and drag it 40 miles to discover that the "Senior Advisor" was wrong and I was right -- for a change -- that it was a failed main logic board, well... I was working against time, I finally ran OUT of time, and all I can come up with to account for the current state of 2TB is that didn't do the CCCloner backup correctly. (I know that sentence is really poor grammatically, but when one has to tiptoe around landmines, circumlocution is better than circumambulation.
Last night, I had to restore Macintosh HD from Time Machine, which worked fine, except I now have literally hundreds of gigabytes of duplicate files (better than lost ones!) spread over 3 drives. The only recourse I can think of now is to use TidyUp! to winnow out the duplicates and try to understand better how to use CCCloner for backups, or surrender and use Time Machine.
Thanks for all your help. I have a couple other projects I wanted to finish up today, but I can see the day is going to be devoted to salvage operations...
I will just add this: The 2TB USB drive I use as a backup for Time Machine has been bootable since before I started using it as a backup, as is my 1TB USB drive, and all three -- Macintosh HD, 1TB, 2TB -- are at OS X 10.6.8. I also manually back up individual items to both 1TB and 2 TB drives.
Bottom line is, I obviously don't quite know how CCC works, and I thought I could back up -- at the last minute -- my internal, regular start-up drive, "Macintosh HD," to a Disk Image with CCC.
As for Time Machine, its constant and unfathomable-to-me backing up drove me nuts, so I turned it off, and used it to back up, manually, about once a week. Stupid? Yes.
Mea culpa

Unreadable Time Machine backups

Had a disc crash a few weeks ago. Caught it in time and did a full Time Machine immediately. It never booted nor mounted again, so I was unable to do a simple disk image or folder copy as I would have liked. So all I have is Time Machine. (I had been traveling for some weeks, and my most recent backup at home is safe and accessible, but a few weeks old.)
I immediately did a copy of the Time Machine according to the instructions at Pondini.org. This was done with "Duplicate the volume", including the "Ignore ownership on this volume" setting, and immediately changing the name of the volume as instructed. So I should have two copies.
Replacement disc (500Gb SSD) is smaller than Time Machine (pretty full 750Gb disc). I found in Pondini that I could selectively restore and then delete folders within the Time Machine. So I went to the Time Machine, and restored Music and Pictures folders to a blank OS X installation, then moved them to a spare disc for safety. Then I selected "Delete All Backups of this folder" for both, to make the backup smaller. This last step I now realize was unnecessary and quite possibly damaging.
Then I reinstalled OS X again, and attempted to use Setup Assistant to transfer the now smaller Time Machine in full to my machine. Unfortunately however, Setup Assistant cannot see any Time Machine backup at all any more. (Nor can Migration Assistant or OS X install at the "Restore from a Time Machine" point.) This I put down to my having deleted some of the folders and therefore having broken it. That would be logical, if very unfortunate.
Next idea was to try the same with the copied version. No go. Nothing will see that either. This I find puzzling as I copied the backup in the correct manner, and didn't touch it again afterwards.
When I use "Browse Other Backup Discs" on both Time Machine backups, I now cannot see any folders of documents, only shortcuts to them which don't go anywhere. So I can't pull the remaining documents from the backup that way, as far as I can see. Or maybe I am looking in the wrong place?
All I really care about getting access to at this stage are the Desktop and Documents folders.
Any thoughts?

I see that you're familiar with Pondini, so maybe you've looked at this already -- but if you haven't, see:

Hope that's helpful.
