Data Recovery of Time Machine Backup From a Corrupted Drive

I had to install 10.2 and 9.2.2 on an internal drive in my 2003 MDD G4 but first I had to reformat it (and wipe out its data) since it did not have OS 9 drivers installed. No problem thinks I since its contents are backed up to my 500 GB Western Digital HD. Installation of 10.2/9.2.2 was successful but when I go back into 10.5.8 to restore the contents of the newly formatted drive the external drive with the Time Machine backup will not mount. It churns and grinds forever and nothing I've tried (after consulting the WD support web site) helps. It is recognized by Disk Utility but that is all.
Any thoughts on whether/how to recover the lost backup? Many thanks in advance.

Well, I am happy to report a happy ending. Turns out DW had crashed but I initiated the procedure again and it was able to rebuild the drive's directory in a couple of hours. Time Machine then recognized the drive and I was able to restore the contents of the drive on which I installed 10.2/9.2.2 earlier in this saga. I will reformat the external WD drive now and see how it performs before I decide whether it's a keeper or not. Thanks for all comments and observations.
Yay!
If those are your only backups, please do yourself a favor: do not trust them to that drive! Get a new one, and put TM backups on one, and use the other to regularly update a "clone" or at least home folder backups via CarbonCopyCloner, SuperDuper, or the like.

Can I transfer Time Machine Backup from WD Hard Drive to Time Capsule?

I have a Western Digital 500 Gb. Hard drive and recently purchased a 500 Gb.Time Capsule which, at the moment, am using only for the AirPort feature. I would like to use Time Capsule for my Time Machine backups and use the Western Digital drive as my Aperture Vault. Is there a way to move the Time Machine file from the WD drive to the Time Capsule drive so that I don't lose the old files? My Time Capsule is connected to my iMac via an Ethernet cable.

Unfortunately, no. Time Machine will backup to a local drive (e.g. via USB or FW HDD) using a folder structure. When backing up to a NAS (e.g. Time Capsule or USB HDD connected to a TC or Extreme), TM utilizes a sparsebundle. You cannot easily convert a folder structure to a sparsebundle. The best plan is to start a NEW backup to TC. Connecting via ethernet is highly recommended for the initial backup.
P.S. You can still access the old TM backups until such time that you want to reclaim the use of the HDD.

Transfer Time Machine backup from one external drive to another

Surely this has been covered, but I can't find it.
If you have your time machine backup on an external drive and get a new (larger) external drive, what is the best way to transfer the backup from one drive to the other (and define the new drive as the backup drive)? Straight copy ? Then to define the new drive, rename old drive to something else and name new drive the backup name?

I haven't tried this yet but a few other methods are described at http://www.macosxhints.com/article.php?story=20071128055047339

Cannot transfer Time Machine backups from one external drive to another

Since I bought my 13 inch MacBook Pro in September 2014 I've been keeping Time Machine backups on an external 1TB Lacie Rugged. This is partitioned into three and one of the partitions contains my iPhoto library.
Last weekend I left my MBP disconnected from the power source but with the external hard drive still plugged in. Long story short - the battery level fell below the minimum needed to operate so it turned itself off and 'disconnected' the external hard drive. This resulted in a corrupted iPhoto library which is no longer accessible.
In order to restore my iPhoto Library from another backup I needed to buy a second external hard drive. Yesterday I bought a 2TB Lacie Rugged which I've now partitioned into 5.
I want to move my Time Machine backups from the 1TB Lacie Rugged to a partition on the 2TB Lacie Rugged (to take advantage of the new Lacie's Thunderbolt connection).
I read the Apple article -
HT202380: Time Machine: How to transfer backups from the current backup drive to a new backup drive
and followed the instructions precisely. About 2 hours into the transfer I came back to my MacBook Pro and saw a message saying that it was not possible to complete the transfer because I did not have the correct permissions. The only option was to click the OK button which stopped the transfer.
Can anyone advise what I should do next?
Cheers

Hi Eric,
Thank you for your response. I came across another thread yesterday which suggested the Restore via Disk Utility method. It worked for me, too. This was after I had tried following the method suggested in the Apple article above three times but each time the message was the same ....
The operation can't be completed because you don't have permission to access some of the items.
I dare say that Apple would like to have us believe that it's a simple matter of 'drag and drop' but it certainly wasn't for me. From what I've read the permission problem crops up fairly frequently. Before the second and third attempts I had already amended Permissions on the Time Machine backups so that everyone could read and write, so that mustn't have been the problem. I'm the only person who uses my computer so that's not a problem.
The next problem I have is that I decided I would use the Restore route to transfer my SuperDuper clone rather than start from scratch. Unfortunately, the partition size on my original backup disk where SuperDuper clone is is 350GB and the size of the SuperDuper clone partition on my new backup is 300GB.
Of course, Apple says you can resize partitions using Disk Utility. What they don't say is you can downsize partitions but (in my experience and that of many other frustrated users on various forums) you CANNOT upsize using Disk Utility. I have 100GB spare on my external hard drive (from downsizing two partitions by 50GB each) BUT there is no way Disk Utility will let me increase the size of SuperDuper partition to 350GB :-(((

How to restore a time machine backup from a corrupted disk

Hi.
I have quite a problem. I recently downgraded to os x 10.5.4 due to the requirements of Digidesign's Pro Tools. I did so with a clean install in order to have the most optimized computer possible without loads of unused data. I had backed up my data using Time Machine on an external hard-drive (LaCie, 1 TB) so I wasn't worried about losing important data.
However, when I inserted my external hard-drive after the clean installation it turns out to be corrupted in some way. It is only recognized in Disk Utility, it doesn't mount on my desktop.
Disk Utility is unable to repair the disk. The errors are:
+Verify and Repair volume “Kristoffer's back-up disk”+
+Checking Journaled HFS Plus volume.+
+Invalid node structure+
+Volume check failed.+
+Error: Filesystem verify or repair failed.+
I went out and bought "Data Rescue II" at once to try to recover my data. It works fine with the stuff I've manually dragged to the disc but the Time Machine backup folders seem compressed in some way (It's only about 86 MB). And when I click a file restored from one of the Time Machine folders it seems like it's just a shortcut to an "original file". I get this error when double-clicking such a file:
+The alias "filename" could not be opened, because the original item cannot be found.+
Is there some way for me to get Time Machine to understand the back up disk even though it's corrupted? Or some other way to retrieve my data?
I have TONS of extremely important data on the disk so it would cost me a huge amount of work to format the disk and start from scratch.
ANY help is greatly appreciated

no, that's quite impossible. you may try using Disk warrior on that drive. it's known to be able to fix the kind of error that DU is reporting. if that doesn't work your only hope is data recovery. If Data Rescue II doesn't work you can try other data recovery software like Filesalvage or try professional data recovery services (those can can a fortune).
Or some other way to retrieve my data?

My experiences copying Time Machine backups from one external drive to another

I am reposting this. The first one was rejected because it contained 'product feedback' and I was directed to the 'Terms of Use'. The 'Terms of Use' say feedback is welcome...***?!?
My 3TB external drive started to die a few weeks ago. It was still under warranty and I just got the new one yesterday. I wanted to preserve all my backups (I had every backup for my late 2012 iMac) on it.
The short of it is that there were like 20-25 million files there or something crazy like that. Finder was going to take forever to count the files. cp and rsync would take like a week. I decided it wasn't worth the hassle, so I just securely erased the old disk and did a new initial backup on the new disk.
The old disk would only mount in read-only mode, so I couldn't prune the backups down to a manageable size. Unless you only have a handful of backups, or you can internally mount the drives to make it go faster, it's going to take forever to do this.

Need to delete old time machine backups from a external drive

was using a 500 gb external drive for time machine so when i upgraded to time capsule 2 tb i just started all over basically. i have these back ups abd videos i wanted to delete from the toshiba dr but appear and attempt to erase securely everytime i need to connect the toshiba to my mac to transfer stuff. i want to use this disk with whats on there like videos and music but i cant seem to figure out how to delete these backups...

Don't try to transfer any old backups to your new TC TM backup drive. Just create a new complete backup. I hope you aren't someone that is trying to store files in a TM backup that you have deleted from your internal hard drive. That is not what TM is for and eventually those deleted files will be removed/deleted from the TM backups.

HT5096 cannot move time machine backup from one ext drive to another. pls help!thanks!

Move Time Machine backup from hard drive to Time Capsule

I have a new Time Capsule. Can I move my existing Time Machine backup from a hard drive to the TC? The tips given back in 2010 in this forum are no longer available.

It is extremely difficult if the disk you are talking about is plugged into your computer.. TM does different kind of file for network drives.. so you need to trick it.
See Q18 here.

Does Time Machine backup other external hard drives?

I am using a Seagate 500 GB to backup my data. Will Time Machine backup another external hard drive on which I store my iMovie projects? If so, how do I access them in the Time Machine mode? Thanks in advance.

nachdenki wrote:
strange, my external HDs were added to the exception list automatically. maybe because they wouldn't fit on the time machine volume.
It seems to depend on when the drives were connected. When you first turn Time Machine on, it only excludes the TM drive itself, and any drives not formatted HFS+.
If you connect a drive later on, that drive will be excluded automatically.

Remove all time machine backups from a certain date and backward

Right, so here's what I want to do: I want to navigate back to a specific date -- for arguments sake let's say June -- and remove all time machine backups from that date and earlier. Is there an easy way to do so without going through every entry in time machine and "removing backup"?
I want to migrate my time machine backups to a new drive, but realize I don't really need EVERYTHING here since its for an older machine. So what I'd like to do is get my rather large 1.5 TB time machine backup down to a more manageable size and then migrate it to a new drive.

I don't recommend deleting Time Machine snapshots. If you have multiple backup volumes, which you should have, and you need to repurpose one of them, you should just erase it. But if you want to try it anyway, and if you're running OS X 10.8 or later (not any older version), see below.
Don't attempt this procedure unless you have at least one other complete backup of all the data. You should have another backup anyway — one is never enough to be safe.
Navigate in the Finder to your backup disk, and then to the folder named "Backups.backupdb" at the top level of the volume. If you back up over a network, you'll first have to mount the "sparsebundle" file containing your backups by double-clicking it. Descend into the folder until you see the snapshots, which are represented by folders with a name that begins with the date of the snapshot. Drag the ones you don't want to the Trash and empty. Sometimes, for unknown and unpredictable reasons, the Trash will fail to empty with a cryptic error message. I don't know of any way to recover from that condition except to erase the backup volume and start over.

How do i install time machine backup from old mac to newer one

Hi, I know how to set up a brand new imac with full info and settings from an old mac from a time machine backup on a portable drive, BUT.... this time i have a 2011 imac in my studio already in use that we want to be completly swapped with full info and settings/software etc from an older 2009 imac, which we may sell on.
I have backup up via time machine the older 2009 mac, but when i plug this into the 2011 imac how do i completly wipe it and set up with info from the time machine?? it was easy doing it on a factoryt new mac but not this.
thanks
lee

If I have understood you properly, you want to migrate the data from the 2009 iMac onto the 2011 iMac but keeping the existing files on it.
To do this, use Migration Assistant > http://support.apple.com/kb/HT4889 It will create a new user with the transferred files from the old iMac.
If you want to wipe the 2011 iMac and restore everything from the 2009 iMac, the most reliable way is erasing the hard drive, reinstalling OS X and restoring the backup. If you are using the same OS X version on both iMacs, you can restore the Time Machine backup without having to reinstall OS X, just starting from the Mac OS X DVD (or Recovery HD, if you have OS X Lion or Mountain Lion)

Downgrading from Mavericks to Mountain Lion WITHOUT time machine backup from Mountain Lion.

Hello. I'm one of the unlucky owners of Macbook Retina 15" Mid 2012. I was very satisfied with this computer, everything was great, untill I installed OS X Mavericks. My computer started to have GPU Panics all the time under some "heavier" usage like watching long videos on YouTube. I googled this problem and then I saw that I wasn't the only one, many people had problems after upgrading to Mavericks. I also read that downgrading to Mountain Lion solves the problem, but after the Internet Recovery update, when you are restoring your mac, it restores as Mavericks. I read Apple instruction how to revert os x, but it requires Time Machine backup from Mountain Lion, I already downloaded ML Installer from AppStore but I don't know how to install it.
Greetings,
Mdkn

If you have a Mountain Lion installer application then you can downgrade, but you will have to erase the drive. You should try backing up your Home folder in advance so you could at least restore your data. You will need to reinstall any third-party applications.
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.
   2. 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.
            3. Use DiskMaker X to put your installer clone onto the USB flash drive.
Wait for the process to complete which will take quite some time.
Use your new installer flash drive to boot the computer. Boot by doing:
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
      "OPTION" key.
3. Release the key when the boot manager appears.
4. Select the disk icon for the USB flash drive.
5. Click on the arrow button below the icon.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
You will need an active Internet connection.

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work. Help?

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work.
^^ that's the main problem. Here's the full history.
I bought a new 13" i5 MBP, early 2011 edition. I had an old white Macbook 2.14 ghz core2duo on Snow Leopard. I attempted to port over my time machine backup, but encountered problems in that my User was inaccessible from the new computer after the import finished, and I had to go in and change the root password, etc, and for some reason or another, I couldn't install any programs at all from that administrator's account. By "couldn't" I mean I could install them, but upon installation they would never boot. So, I took it to the apple store and did a clean install from the most up to date Lion OSX. Then, I created a brand new admin account, instead of trying to import the old one, and things seemed great. Then, I just imported my old files from the TM backup, but not any system settings, permissions, or user data. Just my Docs, pics, vids, apps, and itunes stuff.
Here's where things get weird again. I imported this stuff under the name "old", but all of these folders have a red negative sign on them, marking them as restricted. So, from my main admin account, I cannot even peruse these folders. Since I didn't import user data, I can't sign in to the "old" account to change permissions. I already tried to change the permissions from system preferences, but that didn't change anything. And now, for whatever reason, of all the apps that were imported then, MS Office is the only set of apps that does not work. When I click on it, it just says there was a problem and asks if I'd like to send a report to apple. I tried reinstalling it to no avail. I'm an English student, so i really need access to Word. Can anyone help? The Apple store is a major detour for me and would like to fix this issue myself.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)
