Time Machine can miss files

Since Time Machine wakes up every hour or so and checks FSEvents for changes, it can only see that some changes have occurred in folders and it has to scan those folders to see exactly what those changes were.
If a file is created and then deleted within the hour, TM will may not know of it's existence and therefore the file may not be backed up. Try this by waiting until TM does a backup, create a file, delete it and then check contents of the TM disk after the next back up. The file may not be there.
Does anyone know if this behavior extends to the daily backups? If a file is caught in an hourly but then deleted, will TM know that that file should show up in the daily for that day even if it wasn't there at the time of the daily backup?
The obvious solution to this is not to delete anything important for at least 24 hours after it's creation so that it will be there during a daily. At least it'll be there for a month then.
TM seems to sense when massive changes have taken place and backup sooner than an hour. I've seen it restart in 40 minutes.

I use compost to automatically delete items in the trash that are 7 days old.

This gives me a buffer in case I delete something I need.
And I never have to worry about the trash.
This would solve your problem for backup.

I cannot find this 300GB "Backup" in the Finder, only in the Storage info when I check "About This Mac".
You are probably using Time Machine to backup your MacBook Pro, right? Then the additional 300 GB could be local Time Machine snapshots. Time Machine will write the hourly backups to the free space on your hard disk, if the backup drive is temporarily not connected. You do not see these local backups in the Finder, and MacOS will delete them, when you make a regular backup to Time Machine, or when you need the space for other data.
See Pondini's page for more explanation: What are Local Snapshots? http://pondini.org/TM/FAQ.html
I have restarted my computer, but the information remains the same. How do I reclaim the use of the 300GB? Why is it showing up as "Backups" when it used to indicate "Photos"? Are my photos safe on the external drive?
You have tested the library on the external drive, and so your photos are save there.
The local TimeMachine snapshot probably now contains a backup of the moved library. Try, if connecting your Time Machine drive will reduce the size of your local Time Machine snapshots.

Time machine restore: missing thread record

Hello everyone,
I recently upgraded from Lion to Mountain Lion. I did a clean install. I have been backing up with Time Machine to my Lacie Cloudbox NAS. My NAS requires authentication.
I am unable to restore my files. I have tried it during installation and with Migration Assistant. I can see my .sparsebundle through Finder and mount it (and see an inprogress with loads of folders inside of it). I am unable to copy the files directly to my desktop because of an permission warning.
From Windows I can see loads of files inside the bands-folder. They are all equal in size. I found a clue that maybe the most recent ones are corrupt, so I moved two days worth of them out from sparsebundle.
Disk utility says the drive needs to be repaired. I tried this, and got loads of errors. I there are so many of these that I have shortened the list below a lot. Please help me, all my valuable files are inside the .sparsebundle (510 gigs). I don't care about automation, I just want them out.

The backup disk image is corrupt. You might be able to repair it by holding down the option key and selecting Verify Backups from the Time Machine menu. But that may also result in a total loss of all backup data. Backing up to a third-party NAS is unsupported by Apple and unsafe. You should back up to a locally-attached storage device.

Time Machine Can't find Drive connected to other networked Mac

I have a Drobo external drive array connected by firewire to my primary home computer - a Mac Pro.
For the last year I've backed up two Macbook Pros (mine and my wife's) to this Drobo using Time Machine (The Mac Pro is always on and the laptops backup through the home network, through the Map Pro, to the Drobo).
I recently did a fresh reinstall of Lion to all 3 computers. Now for some reason Time Machine can't kick the backup off. It gives me a "Can't backup - the backup drive us not available," or something like that.
A couple of key points:
* Through the primary computer, I have opened read/write file sharing permissions for all drives, including the FW connected Drobo
* From the laptops, I can see and read/write to the Drobo through Finder
* Through Time Machine preferences, I can select the Drobo as a backup destination - it's only when I kick off the backup that I run into the error.
* If I create a test admin account to try, I get the same problem when trying to back up.
* As a safegard, I have run a manual backup successfully to a separate external drive (mobile g-drive)
What am I missing? Seems like it's gotta be something straightforward - perhaps on the laptop?
Thank you,
-bh-

no - sadly not:)
Okay - I gave it a shot - no dice - here's a screenshot -
Couple of interesting things (at least to me and my limited knowledge...):
* the reset of Time Machine seemed to reset how my laptop connected to the primary computer - defaulted to connecting through AppleID rather than Administrator
* Perhaps I'm using wrong Admin credentials in my File Sharing preferences?
* When I connect to the main Mac Pro ("connect as...") with Admin credentials...though I see the drives and can read/write, it still shows a "connection failed" message above. sending one other screenshot to show you.
Thanks for all your help,

I want to use my 1TB Seagate Hard drive for time machine and transferring files from Mac to PC.

For about a year I've been using my 1TB external hard drive for only time machine. To be honest, it wasn't until today that I tried to connect my hard drive to a PC and realize it isn't compatible. I read about partitioning the hard drive so that it can work both for time machine and transferring files between pc and mac. I'm not what you would call tech savvy, so I was wondering if I can get some advice on how to do this.
Thanks in advance.

To do it, you have to partition the hard disk, so you will have one partition for Time Machine and another one to store files and use them in a PC and Mac. To create the partition, follow these steps > http://pondini.org/OSX/DU3.html
In order to read and write in the external disk on the PC, you have to select "MS-DOS (FAT)" as "Format". If you choose any other option, the PC won't be able to read your external disk. Apart from that, note that you can't use files bigger than 4 GB with FAT. If you want to use the external disk with files bigger than 4 GB, you have to format your new partition in exFAT, and you have to do it on a PC

I have an IMAC and I'm running OSX 10.9.2. I'd like to store my Aperture /IMovie Libraries on an external hard drive. In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives. Is this possible? Can I set up a RAID 5 format for redundancy?

I'd like to store my Aperture /IMovie Libraries on an external hard drive.
That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
You must have backups on a different disk .. otherwise it is pointless.
Can I set up a RAID 5 format for redundancy?
No.. you can buy special USB and Thunderbolt external drives that support RAID..
BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
Raid will corrupt all copies of the files.. it is replicated across all disks.
Delete a photo it is deleted across all disks.. you have no recovery.
Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

I uses Time Machine to transfer files and program from old to new MacBook Pro. Aperture doesn't work. Every time I open Aperture the computer need me to key in Serial number. How do I fix it.

Hi There,
I purchased a new MacBook Pro Retina 15". Since I am using MacBook Pro and I uses Time Machine for backup files and program. Store saleman tell me I can retore my existing program and files from old MacBook Pro to new MacBook Pro computer. After files transfer it seem to be OK. But only Aperture has a problem when every time I open Aperture to edit photos, MacBook Pro ask me to key in the Aperture Serial Number that made me so inconvinent. Did any one have meet this problem and can someone teach me how to fix it, Thanks.

Either the license files were not transferred or it has to be relicensed.
Remove and then re-install aperture. On an rMBP this should take only a couple of minutes.

Time Machine can't copy my hard drive

Time Machine can't copy my hard drive, it says that it can't complete the safety copy because an error occured when files were copied to the safety copy. Does anyone recognise this problem? All I could find in System notifications about Time Machine is this: "localhost kernel[0]: Security policy loaded: Safety net for Time Machine (TMSafetyNet)"

that's the problem -- my hard drive ("startup disk) is not listed, so I can't select it.
The reason is that the startup volume is not a valid selection for its own Time Machine backup.
The only drive listed is the Time Machine external drive. Obviously, I don't want to back up the time machine drive.
By default, a Time Machine backup volume is excluded from being backed up.
The appearance you describe is correct, otherwise I'm completely misunderstanding your problem.

Deleting Time Machine Back-up Files - HELP!

I tried to delete a time machine back-up file from my external drive (to clear space), I dragged it into the trash ... when I tried to empty trash it looked like there were 1000s of files being deleted. That scared me so I stopped the trash from emptying. Now I can't get the file out of the trash. I try to drag it out and it just copies. So two questions: 1) how do I get this file out of the trash? 2) how do I delete all of these back-up files - well, I don't need to delete all of them but there are so many? Do I really need all of these time machine back-ups? If I do delete them - what am I actually deleting? Are they just copies of my harddrive or is it a problem to delete them (when I look in the file that is in my trash it seems like it is my whole system ...). Sorry for all of the questions but I am in a bit of a panic. Also, I did try to delete the files by going into time machine, clicking on the gear icon, selecting a file and clicking on delete, nothing happened. Any thoughts, suggestions, advice most welcome!

You shouldn't have to delete old backups. Time Machine will do that automatically when it needs space for new ones, unless you have the +Warn when old backups are deleted+ box checked in +Time Machine Preferences > Options.+ Just remove the check.
If you have other data on your Time Machine drive, in the same partition, that's not a good idea. It needs to be moved elsewhere, so Time Machine has it's own, exclusive space. See #3 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
The backups have a complex and somewhat unusual structure; there's a bit of "smoke and mirrors" going on there, where it appears that every backup is a full copy of your system, and it is, in a way, but isn't in another. Seems contradictory, I know. See [How Time Machine works its Magic|http://web.me.com/pondini/Time_Machine/Works.html] for an explanation.

You should have gotten a confirmation prompt, then one for your Admin password. If you didn't, the backups may be damaged/corrupted. Repair them, per #A5 in Troubleshooting.

Does Time Machine backup system files (/usr/local/*)?

Does Time Machine backup system files (/usr/local/*)?
If so how do you locate them in the Time Machine interface?
If I go into Time Machine mode and type say "/usr/local" in the Time Machine search bar I get nothing although I can open a terminal application and cd to /usr/local and see bin, lib, include, etc.
Of course I can never see /usr/local in Finder either ... only at the command line.
Thanks.

John, another tech pro ("baltwo") suggests:
Run this in the Terminal:
defaults write com.apple.finder AppleShowAllFiles 1
OPTION-click and hold on Finder's Dock icon->Relaunch which reveals all hidden files. Then, look for that file and delete it. To hide all of those, use the same command, substituiting zero for the one, and relaunch the Finder.

How does Time Machine handle alias files on the backup volume?

I have been trying to find some info on how Time Machine handles alias files on the backup volume, but can't find anything on that topic. Neither here in this discussion or at the Apple support pages.
My concern is if an alias file on the backup volume is backed up »as is«, or if it is resolved and the original file is backed up? The last would be most annoying as this will make the size of the backup much larger.
Even though I do not know of folders having been renamed (which will cause that folder and all its content to be backed up again) Time Machine often backs up a surprisingly large amount of data, so I suspect that alias files could be resolved.
Any info on this will be appreciated.

Alias files are NOT followed, AFAIK.
For more info on how TM works, see this ars technica review.
Good luck!

When I back up on my exertnal HD drive with time machine can I erase what on my computer HD for more space?

When I back up files on my exertnal HD drive with time machine can I erase what's on my Mac HD for space without losing what's on external HD?

If the data is valuable to you, redundant backups are essential. Time Machine is an excellent vehicle when you have to restore data that no longer exists on your internal HDD.
Mende1's suggestion of using Carbon Copy Cloner is excellent because it gives yous a HDD that is 'ready to go' should your internal HDD fail (as all HDDs eventually will).
For example, I have 5 copies of my iTunes folder, one each on three MBPs, on a HDD devoted strictly to iTunes and Time Machine (this does not include the iPod). One may view this as excessive but since I have over 100 GB in this application, I am very comfortable with this.
I advocate that the best backup strategy is Time machine combined with a boot HDD and a third HDD for the most important user data. If there is non essential data, the you may certainly compromise and use just Time Machine.
Ciao.

Time Machine Can Be Made to work with a Network Share

FYI I am just posting this here for the benefit of the community. The source of this info is: http://forums.macrumors.com/showthread.php?t=375047
As I write this, I am doing a Time Machine backup to a ReadyNAS NV+ afp mounted share. Here is a summary of what the thread above says you need to do. It worked for me.
Take any supported USB standalone drive and plug it in to an available USB port.
Use Disk Utility to format the drive (or partition on the drive) and name that partition to whatever you want your network share to be called. In my case, I called it "office-tm".
After you do this, open the Time Machine preference panel and select that new drive (in my case "office-tm") to be the Time Machine backup drive.
After Time Machine sets up the drive, it will start counting down before the next backup. Press the little X on the right side to cancel the backup.
Now open a terminal session and change directories to /Volumes/<drive> where in my case <drive> was office-tm (cd /Volumes/office-tm).
When you do a ls -a -l, you will see two important files. One starts with a period (.) and contains numbers after it. The other one is called .com.apple.timemachine.supported.
What you need to do is copy these two files to your network share. The trick is that you want your network share to have the same name as this drive you just prepared (again, in my case it was called office-tm). I first created a new share on my ReadyNAS+ called office-tm and set the quotas properly.
Then you need to copy the files. There are several ways to do this but the way I did it was that I temporarily mounted the network share at a different mount point in terminal just to get the files over. So for example, I did:
sudo mount -t afp afp://<ip.addr.of.share>/office-tm /Volumes/office-tm2
Then I copied the two files over (substitute your appropriate volume names):
cp /Volumes/office-tm/.00whateveryourfilenameis /Volumes/office-tm2/.
cp /Volumes/office-tm/.com.apple.timemachine.supported /Volumes/office-tm2/.
Turn off Time Machine so you can unmount.
Now you can unmount both the USB drive and the network share and then you remount the network share as the proper name. The same one that the USB drive was named so as far as Time Machine is concerned, the volume is still there. The two files are on the network share so all is fine and Time Machine can find the volume it expects.
Wait for Time Machine to start it's hourly backup and away you go.
PLEASE NOTE THIS DISCLAIMER - There is probably a good reason why Apple disabled this feature so you might want to think carefully before you rely on this hack published in the MacRumors forum to back up your Mac. I am using this for testing purposes only and I am still using traditional backup techniques for my "real" backup of my office machine. If you don't get good Time Machine backups and you have relied upon them for critical data, don't blame anyone but yourself.

Reason: Final 6.
We should probably start a new topic in networking on this. I am seeing some strangeness with afp shares as well.
I have most shares set up to allow access by both CIFS/SMB and AFP. If I use Sidebar and try to access the shares by AFP, it says it can't connect to the server. But the same shares via CIFS works fine. (I can click on the "Windows" server icon and connect.) But for any of these shares, I can manually connect with the normal Go > Connect to Server... method, specifying afp://<ip address> and that works fine.
In the case of the Time Machine share that is the subject of this post, I disabled CIFS and am only using AFP because I wanted to make sure I connected to the share only via AFP for Time Machine purposes.
BTW, I do not use USER or DOMAIN security mode in my case and my shares are set up as SHARE security mode.

Time machine and extra files?

Hey yo,
If I get an extra Hd to use for Time Machine can I also use that Hd to store and access say Audio files for Pro Tools? Im looking into getting an additional HD to store a image of my Hd for backup purposes and figure while Im at it I could just get a larger HD and store my audio files for PT to it. Since the logic is that Pro Tools runs faster and better if you put your audio files on another HD that is not you boot hd. Can I do this?

Hi Damballa,
Time Machine's backup folder can coexist together with other files, however it would most likely be better practice to partition the drive into 2 parts in disk utility. 1 part for time machine, the other for your audio files. That way, it keeps them separate from each other, which is always better imo, especially for time machine.
OR, since you have a Mac Pro, put those 4 HD slots to good use! Buy 2 HDs!
They are so affordable right now. I'm not sure your main drive size, but Western Digital 640GB drives are simply awesome: speed, price, size. $75 for what you get..is sick.

If I were you, use the WD 640s as your main drive, great boot times.

Lion's Time Machine - Can't create a backup?

Time Machine can't make a backup... I even went ahead and wiped out the drive and tried to create a new backup.
All it says is that it couldn't complete the backup and to try later as it might only be temporary.
This is critical for me and a not at all light in importance. Had I known this along all the other issues with Lion existed I wouldn't have upgraded. For now I am keeping my MBP safe from Lion...
I guess I just have to suffer the damage on my 27" IMAC..
I would use a BR Disk to do a back up of my files, but NO.... MACs don't support Blu-Ray disk drives, STILL!!
Apple you need to fix this and other issues.

Apple's ingenuity in their advances can be hailed by millions as I myself give them credit where credit is due, such as devices like the iPad and iPhone/iPod. But when a company only bothers to alert you to a couple of apps that Lion can't run and moves them to a folder for the user to delete or update but leaves devices and other industry standard software packages rendered useless with no warning when they have extensively tested their OS against 3rd party manufactured devices and software, whom they are partnered with, then yes they can share in the blame just as Microsoft takes the blame for operating systems that do the same such as VISTA.
I am sure that with enough time all of the 3rd party companies will undoubtedly get on board at some cost that will get pushed down to the end users. They will either update, upgrade or conform.
Apples mentality in the past hurt their stock prices, they used to only use their own Risc based processors and they refused to adapt and incorporate to the needs of their users desires for better faster chipsets and industry software such as Office. They adapted!
Refusing to incorporate the ability to use Blu-Ray technologies when companies such as Pioneer,LG, and Cyberlink are prepared to release the software for the Mac, Apple just has to give the go ahead, then yes, its their fault again. The industry in general isn't blind, they have a reason. Manufacturers want to create things that work with Apples Operating system and do, but they aren't allowed to release it without approval from Apple. They need Apple's support and acceptance for something like Blu-Ray to make it. Otherwise its just another hack and shunned by any cautious person that wants to make sure that their purchase won't cause them more problems than its worth. Blu-Ray is a matter of licensing and a major reason that Microsoft won't incorporate it into their own media player, but they leave it up to 3rd party software companies to absorb that cost and create their own players that can play back Blu-Ray movies within the Windows platform. Apple wants to keep Blu-Ray off of their machines as they can't obtain an exclusive license to the codec for Blu-Ray movies for Quicktime. The same mentality that they had before with their processors. So even the ability to read and write to the medium is out of the question.
