Time Machine from SL to Lion

Hi,
With the new upcoming OSX upgrade, questions started to comeup. I’m currently using SL with TimeMachine to back-up my files to an external hard drive.
My question is, will I be able to continue using TimeMachine without formatting the external drive or do I need to re-format thedrive if I want to use it with Lion?
I’m just afraid about any incompatibility Lion may find withold backup files.
Thanks

Nobody who knows more than Apple has made public is allowed to say anything more until Lion is released.
But that was not required when upgrading from Leopard to Snow Leopard, and there's no reason to think upgrading won't be seamless this time. Apple has always made upgrading easy and automatic.
We should know soon. Patience.
Be more concerned about compatibility of your 3rd-party apps and hardware.

How to stop time machine from backing up encrypted lion partition

I am using 10.6.8 but I created a Lion partition on the same disk. I am trying out Lion and I do not want Time Machine to back it up. I was able to exclude the Lion volume until I encrypted the Lion partition using Filevault 2. Now when I'm using Snow Leopard, there doesn't seem to be a way of preventing Time Machine from backing up the Lion partition. Am I missing something?

The FAQ says Snow Leopard can't read the Filevault 2 disk which seems to imply I won't be able to keep Time Machine from backing up the Lion partition. That seems wrong. How can Snow Leopard's Time Machine see the disk to back it up, but can't see it to exclude from backup?

How to disable Time Machine from backing up to hard drive

Mountain Lion (OSX 10.8) will not install onto iMac (under OSX 10.7.4) because: "hard drive is Time Machime backup disk" error message. However, TM Preferences does not show the iMac HD as a TM backup Location Option - it only shows the LaCie External Drive - which has been the storage drive receiving the Time Machine Backup. How do I remove/prevent Time Machine from looking for and/or backing up to the iMac Hard Drive if the TM Pref does not list the iMac Hard Drive as an option? Note: The iMac HD icon on the desktop is a "Time Machine image" (blue Drive icon w/white white counter clockwise arrow). Thanks.

Check to see if you have a file called backups.backupdb on the hard drive you are attempting to update.
If the install procedure see such a file, it might think that it is a TM backup drive.

Migrating from Time Machine from old iMac to new used iMac.

So, I bought a used iMac, and want to migrate to the new one using my Time Machine backup. Problem is, I go to Migration Assistant, and it asks for the admin password, which I don't have, and the place I bought it from is closed, of course. I had Lion on my old iMac, and I imagine my Time Machine backup is in Lion, but the iMac I bought has Snow Leopard. What do I do to migrate?

Yes, you will need the Admin password. See http://www.cultofmac.com/111456/discover-the-hidden-password-reset-tool-in-lion- os-x-tips/
Then follow the instructions in option #4 of the box in the green box in Problems after using Migration Assistant. (I know you haven't used it yet, but to transfer your user account(s) properly, without losing permission to your backups, that's what you need to do.)

Even via time machine the new osx lion has deleted all my latest files in iPhoto and will only revert back to an old 2009 backup?

even via time machine the new osx lion has deleted all my latest files in iPhoto and will only revert back to an old 2009 backup?... Help?!

Have you verified that the original files are missing from the Originals/Masters folder? There are time when the library might appear empty due to a damaged database file but still has the files. If you can open the library package via the Finder to see if the files are really missing or just can't be seen by iPhoto there are fixes you can try.
If the files are there make a temporary, backup copy of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Many thanks!

Let me know if is all ok.

HT201250 Time Machine backup then install new SSD HD + Pulling files from Time Machine from 'old' HD

Hi Guys,
I currently have a mid 2009 Macbook pro and I decided to upgrade the current HD in it to an Intel 330 SSD. Which might I add was a *gongshow*.
Anyways before I did the switch I used Time Machine to back up all my information, and to be double redundant I backed up the REALLY important information on a 8gig flashdrive.
The removal and reinstall of the new drive went smooth, and once lion was installed I did all the usual system updates.
Once it came to importing files from Time Machine is when my hassle started.
The last backup I did on Time Machine with the old HD still installed was at 10:00 this morning.
I had the new SSD up and running and a new backup of that created by 1:00 (3 hours later).
When I loaded up Time Machine to grab some files off of my 10:00 backup, it would not let me. The current backups have a Grey/Silver snapshot, and the backups from the OLD HD were blacked out and I could not click on them. What can I do to get these files off my Time Machine from the old HD?
Thanks

Quick followup question,
If I do a migrate with the time machine will the system be updated to the version I had when I made it (10.8.6 I think) or will I have to do the system updates afterwards. If so, will that cause any clashes when applying the time machine migration?

Using a time machine backup of Mountain Lion on Mavericks

I have just installed Mavericks with a clean installation from Mountain Lion. I have a time machine backup of Mountain Lion, but I do not want to use this backup to restore my system because I have a lot of problem and I would like to be sure that is not a problem connected to the software.
Can I use the previous time machine disk as backup of the new operating system without losing the previous backups?
If I use it, I cannot restore the system with the "Mountain Lion" state with the migration assistant, is it true?
Thanks

No. Time Machine will be replacing your existing backup with a new one of your Mavericks system. If you wish to replace Mavericks with Mountain Lion, then I suggest you replace it with another backup of Mountain Lion, if you have one. Otherwise, if you've permitted Time Machine to run since installing Mavericks, then you not longer have a Mountain Lion backup.
You will need to go to your Purchases page in the App Store and try to re-download your Mountain Lion purchase. If you can, then after the Mountain Lion installer downloads and opens quit the installer - do not run it. Now do this;
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.
Now, run the installer flash drive, erase the hard drive, and reinstall Mountain Lion. You can then use Time Machine just to replace your data from your Home folder.

How do I stop Time Machine from backing up Aperture thumbnails?

Hi,
My 2TB backup drive recently became full, and I became curious as to what was filling it up. I wrote a perl script to analyze the Time Machine backups, and I noticed that over 50% of my backup was filled with AP.Thumbnails and AP.Minis from the Aperture project directory. In particular, the AP.Thumbnails files in the backup consumed 737 GB of disk space!
The problem with the thumbnails files is that they are a single file that contains all of the thumbnails for all of the 40,000 photos I have in Aperture and it is now 20gb in size. Every time I add a new file to Aperture, the thumbnail file changes, and I get a new 20gb of data added to my backup. I add photos often which means that most of my backups have 20gb of Aperture files (which are easy to rebuild and don't need to be backed up).
I decided to try and stop Time Machine from backing up these files, and there seems to be no way of doing so (without telling Time Machine to skip backing up my entire Aperture project which I don't want to do). In Finder, you can do a "show package contents", but the Time Machine GUI doesn't allow this.
I tried to tell Time Machine to exclude the files via the GUI, but Time Machine sees the Aperture Library as a single package and won't let me exclude individual files from within the package.
I googled around, and found the attribute that Time Machine puts on files to exclude them from the backup. I used xattr to set the attributes:
xattr -w com.apple.metadata:comapple_backupexcludeItem com.apple.backupd <filename>
I also used this command on the iPhoto thumbnail files.
I used spotlight to find all of the files with this attribute using this command:
sudo mdfind "comapple_backupexcludeItem = 'com.apple.backupd'"
This command returned the iPhoto files, but did not return the Aperture files.
However, if I run "xattr" on the Aperture files, the attribute does exist!
During my next time machine backup, the iPhoto files were skipped as I wanted them to be, but the Aperture thumbnails were backed up again
I thought that maybe time machine was looking at the aperture package as an atomic unit, but iPhoto is stored as a package as well, and the attributes worked there on files inside the package.
Does anyone have any idea why time machine is still backing up these files? Is there any way I can get around this?
It seems to me to be an incredible oversight on Apple's part since both tools are Apple. The thumbnails files are very expensive to backup, and they are not necessary for backup since the are easy to rebuild from the original photos which are also backed up.
Thanks,
Ron

No need to write your own script for that. there are a couple of already made nice GUI tools for this - TimeTracker http://www.charlessoft.com/ and BackupLoupe http://soma-zone.com/BackupLoupe/
and I noticed that over 50% of my backup was filled with AP.Thumbnails and AP.Minis from the Aperture project directory. In particular, the AP.Thumbnails files in the backup consumed 737 GB of disk space!

I don't have aperture but I think most people exclude the whole thing from TM backups and back it up separately. but if you want to exclude a subfolder in a package that's easy too. just select the package in finder, control-click on it and select "show package contents". in the resulting finder window drill to the folder you want to exclude and drag it to the TM exclusion list in TM system preferences->options.
I googled around, and found the attribute that Time Machine puts on files to exclude them from the backup. I used xattr to set the attributes:
xattr -w com.apple.metadata:comapple_backupexcludeItem com.apple.backupd <filename>
I was not aware of this method for excluding stuff from TM backups. could you provide a link to where you found this?
I also used this command on the iPhoto thumbnail files.
I used spotlight to find all of the files with this attribute using this command:
sudo mdfind "comapple_backupexcludeItem = 'com.apple.backupd'"
This command returned the iPhoto files, but did not return the Aperture files.
that's because Spotlight never looks inside packages unless you start a search inside a package directly. iphoto seems to be the only exception. I don't know how it's done.

How do i use a Time Machine from another computer from Time Capsule with multibackups

Can Iuse a Time Machine from another computer from Time Capsule with multibackups

Not sure what you are asking here.
Time Machine is software on a Mac that is used to backup that Mac to a Time Capsule hard drive.
Are you asking if another Mac can backup to the same Time Capsule that other Macs are already using?
Or, if not....please clarify on exactly what you want to do.

How do I move data on time machine from one external hard drive to another

How do I move data on time machine from one external hard drive to another?

Although the documentation says you can copy Time Machine backups in the Finder, it's very slow and sometimes doesn't work at all.
Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions. Turn Time Machine OFF in its preference pane while copying the volume.

Can I back up to Time Machine from hard drive of failed Macbook?

My Macbook has just completely failed (I think an issue with power supply).
I had a bulging battery and have a new Macbook Pro on the way, but as I live in a very remote area this is taking a while. So, one day, my Macbook just wouldn't start again.
I hadn't backed up to Time Machine for about a week and would really like to get all the missing data. When the new computer arrives I'm planning to use Migration Assistant to migrate all my data from Time Machine.
So, my question is, is it possible to back up to Time Machine from the hard drive of my dead Macbook? I was thinking either cloning it somehow, or making a disk image and booting it from another Macbook, but this is stretching the limits of my limited IT skills. I don't want to interfere with the other Macbook I'm using or inadvertently wipe the data on the hard drive or Time Machine disk.
Any advice much appreciated!
My Macbook ran Snow Leopard and was up to date with software updates as of two days ago. It was purchased about two years ago, but I think it's manufacture date was about March 2008.

Thanks Noondaywitch and Pondini!
The HD of the failed Macbook turned out to be fine. Just to be safe I did a full functional back-up of my Time Machine disk to another external disk as well as cloning my Macbook hard drive using Carbon Cloner to another partition of the external disk.
I then booted from a friend's Macbook and did an incremental Time Machine backup from the original Macbook HD to the original TM backup (making sure I excluded the host computer's hard drive from the backup!); when I did the backup it asked whether I wanted to "Reuse backup" I clicked yes.
As said, the hard drive was fine, but at setup I needed an ethernet or firewire connection, which I didn't have on the enclosure, so I migrated my data to the new Macbook Pro using the original TM backup. Strangely, the backup said it was transferring only 120GB, whereas the HD had 150GB of used space. Redundant files, etc. perhaps? Anyway, it's just transferring now, so will sit back and read the paper and see what it looks like in an hour and a half!
Thanks very much again!
Now, if anyone's got any suggestions to fix my old Macbook, which I was going to give away to impecunious friends if they bought a new battery……
HD is fine, power seems buggered, the rest, I don't know. Suggestions welcomed (I live 300+kms from the nearest service centre, so it's strictly DIY or go to local computer shop who know nothing about Macs).

How to stop Time Machine from backing up Temp Files?

Hi folks!
I am trying to find out how to stop Time Machine from constantly backing up 'useless' temporary files accumulated from web browsing? Although I don't change or add large files to my HD, Time Machine backs up hundreds of MBs every hour. Those file amounts make sense when I consider that I browse a lot to YouTube, SoundCloud, etc to watch videos or listen to music - I just don't want them to be backed up.
Under Time Machine Options I already excluded the following items from backups:
~/Library/Caches
/Library/Caches
~/Downloads
But even though I did this weeks ago, Time Machine stills finds large files to be backed up every hour and my only guess is that I am still missing a location where either Safari or Firefox - the two web browsers I use - store temporary files.
Can you help?
Thanks a lot in advance!

Are you sure you need that? There are no viruses that run on OSX. None. Zip. Zero.
If you're running Windoze on your Mac, that's the same as running it on a PC, so it needs all the same anti-everything stuff you'd use on a PC.
There is some "malware," such as Trojans, for Macs, though. But (unlike viruses that can get onto your system without your knowledge), you must approve their installation (via your Admin password) and/or operation (via the "This application was downloaded from the internet ..." prompt).
Appropriately enough, some of these Trojans are included in pirated versions of Apple software, such as iWork!
For the gory details, see Thomas Reed's [Mac Virus Guide|http://www.reedcorner.net/thomas/guides/macvirus].
Thanks a lot again!
You're quite welcome, and thanks for posting back.
