In migrating to a 21.3" iMac from a Time Machine backup, can I do this more than once?

David,
My apologies....I was working on questions from a different thread and thought yours was part of that one. Your question is fine where it is....
Now....that being said, I'm afraid I don't know the answer to your question. I know you can exclude certain items from being backed up in Time Machine, which would save disk space on your external drive. But, you'd first have to calculate how much disk space you're using for the different things you want to back up vs. those you want to exclude.
I think it MIGHT be possible to do what you want, but (in my honest opinion) it's a recipe for a LOT of headaches should things not work out as you calculated. Better (again, in my opinion) to just pick up a larger external hard drive and transfer everything as Time Machine was designed.
Just my $0.02 worth.

How do I migrate from a Time Machine backup of a larger hard driver to a smaller hard drive?

My old MacBook Pro has a 1 TB drive. My new one has a 256 GB drive (SSD, as you might guess). I want to use Migration Assistant to move my files from my Time Machine backup to my new MBP. But obviously not all the files are going to fit. If I leave out my music and movies and a couple other things then it will work.
So I selectively migrated just the things that would fit, thinking that I could then fire up Time Machine and restore those other files to an external drive. That doesn't work, though, because my new computer is not recognizing the old computer's Time Machine, and instead is trying to create a new Time Machine area.
What's the best way to solve this problem? The end result I want is for my users and applications to be restored to the new computer, and my movies and music to be restored to external storage.

Aha, I think I found my own answer. I had to Browse Other Backup Disks by Alt-clicking the Time Machine icon. Then I could find the directory I wanted (iTunes Music, for example) and right-click on that to restore to a different location.

Bought a new iMac migrated from a time machine backup and it didn't load contacts music etc

my 4 year old imac died. So we got a new 1Tb intercore i5 imac. Migrated from the time machine backup and it didnt populate itunes or contacts or photos. Am I missing something?

You should have imported the data in Setup Assistant when you first booted the new machine. If you used Migration Assistant instead, you now have another user with all the data from the old machine.

I have just taken delivery of a brand new 15" macbook pro, tried migration assistant from a time machine backup, music, photos, programs etc. They now take up 350gb of my hard drive but the files are nowhere to be found? can anyone help?

Set migration assistant to run whilst on a lunch break, given that it needed 2 hours or so, when i returned all programs and applications had moved across from my time machine backup of a now dead 15"macbook pro 2009 edition running snow leopard...When i look at my new system information it shows my new 500gb drive is full of music, movies and photos and has only 168gb free, not enough to run a new migration and i don't have any boot disks for Lion so really don't want to erase the hard drive. To compound the problem i'm in Vietnam where there isn't a genius bar just around the corner, or even an aasp within 700km - what should I do?

Is the HDD in the 2009 15" MBP dead? (The original source of your data) If not, you might want ot take it out and put it in an enclosure.
You might try spotlight on know files to see if that gives you any clues where your data is located.
You might down load from the Internet OmniDiskSweeper (free) and open it. It should show you all of the files you have on your MBP and enable to locate them.
Ciao.

Just bought a used MacBook pro after my previous died. I want to migrate my applications, data, etc from a time machine backup of the old computer to the new. Will this affect, or overwrite the Apps., data, etc existing on the new machine?

No. Only those Apps that are not installed on the new will migrate over.

HT1199 I needed to restore my Imac (lion) from a Time Machine backup on a peripheral HD. Everything woirked fine except none of my Pictures showed up and my TM backups were all erased. Any way to recover??

I need to perform a complete restore of my IMac from a stand-alone HD Time Machine backup. The restore was to the internal HD in the IMac. The IMac is a new Intel i5 unit running Lion. The restore went fine except none of my picture files appeared. My external HD is partioned into a Time Machine Back Up and a Stoarge partion. All the TM back ups prior to the restore are gone and the external storage was wiped clean. 3000 photos from our African Safaris are gone. Any ideas on if they can be recovered from either the external storage drive or the internal HD?
Where did the older TM BUs go?
Thanks for any advise

Hello:
I don't know what you did, but there must have been some option to clear the external HD. To my knowledge, restoring from a Time Machine backup will NOT clear the external HD.
Since I was not there, I really cannot speculate on what happened:

In any event, there are third party tools that will attempt to recover data from erased drives (the erase normally deletes pointers, not the actual data).

Vexing migration from a Time Machine backup

When I went to set up my new machine I elected to migrate from a Time Machine backup; imagine my surprise when the process was completed and I was staring at an exact duplicate of my old machine-only as it looked back in late 2007. I've been backing up fairly regularly, but only when prompted by Time Machine. The last backup I performed was several days before I purchased the new machine.
I opened Time Machine and was surprised to see no backups displayed, and of course no Restore option. In the course of browsing the backup medium I discovered two folders in the backups.backupdb directory named Joe Blow's Computer and Joe Blow's Computer 2. The last backup in the JBC folder was dated November of 07, and was to the best of my ability to determine, the one that was migrated to my new machine. The JBC2 folder contained all of the subsequent backups; I could browse it directly and using the Browse Other Disks option in Time Machine, but was unable to view any of the backups without first modifying the permissions.
My initial fear, that all of my post-2007 data was lost, is no longer an issue since I've simply copied all of my files from my last backup to my new machine, but I'd really like to figure out a way to re-do the migration and get my old machine moved over to the new hardware in its entirety. Given the clarity of 20/20 hindsight I probably should have just done a machine-to-machine migration via firewire, but at the moment they're not in the same location and won't be for at least a month or two.
In the research I've done so far I've seen the issue of MAC address changes implicated in similar problems; my old machine is in its original configuration with all of its originally installed components. Thanks in advance to anyone who can shed some light on this for me.

Yes this is an interesting issue. I was wondering what would happen in such a given situation because I feared it would create problems. It makes you wonder what the need would be for time machine if it can not assist you in case your computer lets you down.....

Migration Assistant from a Time Machine backup

I have a 2009 MacBook Pro. I recently had the hard drive replaced, and now I want to use Migration Assistant to restore settings and files from a Time Machine backup. The backup was done to a hard drive connected to an Airport Extreme. I am attempting to restore with the drive directly connected via USB. Migration Assistant does not recognize the backup as a source for the migration.
This is what the backup disk looks like:
If I mount the backup I see this:
I have the drive connected and the backup mounted, so neither is recognized for the migration.

Try using Setup Assistant.

HT201250 After restoring from a time machine backup using migration assistant I can't log in

Hi, I recently bought a Mac Pro and using a Mountain Lion boot disk I made installed a fresh ML install which went fine. During the final part of install it gives you the option of restoring user data etc etc from a time machine backup which I have from my MacBook Pro which again in principal went fine until I went to log in when I got the message 'An error has occurred unable to log into this account a this time'.
Looking on the web I thought at first it was a password issue so restarted with command-r and reset the password, however the same error still occurs. I don't think it is password issue as if you deliberately enter the wrong password it rejects it immediately where as with the correct password it hangs for about 15secs before throwing up the above error.
Can anyone offer any advice?
The only thing I can possibly think of is that on my MBP where the time machine backup is from my home folder is on a 2nd HDD that is not the boot disk and I only have a single HDD on my MacPro.......

You might try to access the desired Time Machine backup from "Browse Other Time Machine Disks" (click Time Machine icon in the Dock).
Also, you might find some help here.

Recovering single file from old Time Machine Backup

I see many questions/answers that almost address my issue, but not quite, so I'm starting a new post. If this has been answered somewhere and I missed it feel free to just refer me to the correct post!
I recently had to do a full System Restore from a Time Machine backup. The good news is that it worked beautifully and I'm using my iMac like nothing ever happened. When Time Machine tried to run (post restore), it said I didn't have enough space on my external drive. Okay, based on other posts here I see that it won't just continue from the old TM backups and it's starting "anew"...got it.
The old TM backups must still be on that drive because it shows 144GB USED and 100GB AVAIL of my 250GB external drive. Okay, again based on other posts I know that I could just wipe the drive clean and start fresh...BUT...
I restored to my TM backup of 8/24....now I realize that there are one or two files that I at some point stopped having TM backup and now I want to get them back (the whole point of TM, right?)...I figured since it's "holding" that space on my external drive, the old backups are intact and I just need a way to get to them to pull them back to my restored system, then start TM from scratch.
I can't get at the old TM backups. I've tried:
1) Using the "Browse other Time Machine Backups..." feature. It doesn't see the old TM backup...sees the drive, but nothing on it.
2) Browsing the drive in "Finder"...nothing shows up...just the attempted NEW backup.
3) Connecting the external drive to an entirely different Mac and trying to browse the disk in Finder OR use the Browse other Time Machine Backups...still nothing.
So I have a 250GB drive that shows 144GB used, but no way to even view what that is....am I out of luck? Or would something in DiskUtility or a 3rd party software (DiskWarrior) help in this situation?
Is there any way to go pull one or two files from my old TM backup?

Exactly Glenn....I did nothing to the hard drive after the "restore from Time Machine Backup"...
I've never used the Migration Assistant...have to look into that.
I didn't want to be argumentative since I was the relative newbie asking for help, but I HAVE to believe that if I didn't write over the files (i.e. reformat the drive), AND the Finder is recognizing that there are 144 GB USED, the files must be there, untouched....
The urgency isn't there for me anymore, I've already re-created the one doc I wanted to recover and the other file was my Windows XP virtual machine file...(I didn't want to have to re-install Windows from scratch - but I did)....so maybe this is a good time to "play" with that drive while I can afford to lose everything on it!

Mail from Lion Time Machine Backup to Mountain Lion

Hello,
My Lion iMac is crashed and now I want to put my Mail database from Lion Time Machine Backup to my Mountain Lion Mac Mini.
In Migration-assistent under Users there is no topic for Address Book, Calendar and Mail. Also the helpdesk told me not to use the migration-assistent but doing it manually.
How can I add extra accounts from the Lion Time Machine Backup ?
I have already <emailaccount1> working on my Mac Mini. It is just merging <emailaccount2> upto <emailaccount7>.
Is it just copying Library/Mail/V2/POP-<emailaccount2> to ~/Library/Mail/V2/POP-<emailaccount2> or do I have to change something under Preferences ?
Thanks,
Hubert

Hello Sig,
This helped but the original mail data is deleted completely. I tried it on a dummy account and discovered that the original data of <emailaccount1> is deleted by copying the Mail folder onto the original one.
So I made a copy of the Mail folder before overwriting it. Then I copied the deleted mbox files back to the Mailboxes folder and started Mail.app.
Thanks,
Hubert

Restoring data from a Time machine backup of a potentially corrupted drive

I seem to be the queen of failing hard drives, heh. I'm on my third in a year, and will be addressing the root cause of these failures, of course, but right now, I'm wondering how safe it is to restore from my Time Machine backup. Here's the scenario:
-- Drive started throwing I/O errors, detected via SMARTReporter, about 2-3 months ago. No change in how the machine functioned, all OK.
-- I continued to back up daily to TM & Crashplan
-- While traveling for a month (and not backing up anymore, I left TM home), the machine started acting funny. Finder freezing, etc. I decided to clear some caches (by booting into safe mode) and see what happened.
-- This caused the HD to fail completely. Recovery mode, target disk mode, booting into single user mode and command-lining fixes, and DiskWarrior all failed to rebuild the directory. Failures were in multi-linked files/directories, the catalog file, etc.
-- I ordered a warranty replacment drive (and a new hard drive cable for starters).
When I got home, I borrowed another machine and just did a Verify Disk on the TM backup. It came back totally clean. So, my question is: is it safe to restore the data from my TM backup to the new drive when it arrives?

Shouldn't be any problem.
Boot from your SL installer DVD (hold down the C key on startup or hold down Alt/option on start and choose the installer disc).
OK the language page (if present). From the installer screen, go to the menu bar and choose Disk Utility; depending on the OS version it may be in the Utilities menu or Tools menu.
In DU, select your internal drive in the sidebar (the top item with the makers name and serial no.). Run Repair Disk. If that comes up as disk OK, click the partition tab. Select the partiton from the drop-down above the graphic; 1 partiton is all you need. Go to the options button and ensure that the partition scheme is GUID (for Intel Macs) or APM (for G5 and earlier) and the file system to Mac OS Extended (Journalled). Name the partiton (usually Macintosh HD), click Apply.
When that's finished, select the new volume in the sidebar (indented to the right below the drive) and go to the Erase tab, select Security options and select zero data (one pass is more than sufficient). Click erase. That will take quite some time; probably measured in hours and dependant on the size of the drive.
When that's completed, close DU and continue with the installation.
Shortly into the installation process, you'll be asked if you want to migrate data from another source. Select 'from a Time Machine Backup' and follow the prompts.

That should leave you with the same setup as you had on the previous MB.

Can i restore from a time machine backup that is not the latest one?

I am trying to restore from a May 7th time machine backup. At that time my username was michaelhood. I had a system crash and when my computer was returned to me I inadvertently set it up under a different username, thinking I would do the restore later. Between May 13 and today, Time machine did backups under the name mhoo4494. Changing the name didn't let me access my May 7 backup, nor did creating a different user account. I have erased the hard drive and am reinstalling from the Install CD. I have set up a third user name. I now want to restore my data from the Time Machine May 7 backup. How do I do that? Migration assistant saw two users -- mhoo and mhoo4494 (michaelhood was not an option). I selected them both, but got no data for either -- no docs, no music, no pictures. This procedure should not be this hard~!!

Hi uclamikey90,
It is possible, using Migration Assistant, to restore the contents of your hard drive selectively. See this article -
Mac OS X v10.6: How to use Migration Assistant to transfer files from a Time Machine backup - Apple Support
In particular -
To migrate data from a Time Machine backup
In Finder, press Command-Shift-U.
Double-click Migration Assistant.
Click "Continue" and enter an administrator name and password when prompted.
Select the "From a Time Machine backup or other disk" option, then click "Continue".
Select your Time Machine backup disk or Time Capsule (enter the user name and or password if prompted), then click "Continue".
Select the Time Machine backup you would like to restore (such the most current one you just made), then click "Continue".
Select Items to Migrate, then click "Continue". Note: The "Continue" button will be dimmed until the "Calculating…" stage is complete.
A user account sheet may appear if you have a user name on your Mac that is the same user name in your Time Machine backup. You will have to give the username in your Time Machine backup a new username to avoid conflicts. Note: This will create a new user account on your Mac to hold the data from the Time Machine backup. After migration, you can use the /Users/Shared folder to transfer data files the accounts.
Migration Assistant will begin the process of transferring the items you selected to migrate. When it is finished, click "Quit" to exit.
When you reach step 7, deselect items that you do not wish to migrate. Videos, photos and music are likely candidates for this as they take up a lot of disk space. You can later put items on an external hard drive.
Thanks for using Apple Support Communities.
Best,
Brett L

Any way to restore iTunes and iPhoto libraries from failed Time Machine backup?

Is there a way to restore iTunes and iPhoto libraries from an unmountable Time Machine backup?
Background: I received an update alert on my iMac (mid-2010, 1TB) from Time Machine (wirelessly connected to a Time Capsule, 2TB 2013) that it required an update and required rebooting, of course, it happened when I was in the middle of a project and I postponed the restart for later. That evening I turned off the computer and coincidentally the next morning, the iMac would not start; it loaded to the Apple logo and about an 1/8 of the progress bar would load before the iMac would turn off.
The iMac had been fine to that day (OS upgrades and all since 2010) so I was assuming something misfired when I declined the Time Machine update. I tried the PRAM and SMC resets mentioned in the forums but no dice. I then went into Disk Utility to try repairs and there were errors on the hard drive that could not be fixed. My next step was to erase the drive and restore from my Time Machine backup. Before doing that I checked Disk Utility and to my horror, it told me that my Time Machine backups were unmountable so of course my first thought was that all my files were gone.
The TC was under warranty so I called support and they referred me to the local Genius Bar. The Genius was great and showed me that my files weren't lost even though the Time Machine backup was unmountable. They recommended I erase the partitions, starting from scratch and I would have to transfer the Time Machine backup files manually by directly connecting an ethernet cable from the TC to the computer. If that didn't work, the hard drive was bad and needed replacement which they could take care of.
I followed their recommendation and the hard drive is fine. I was so relieved to hear that my files were safe that I forgot to ask about all of the metadata that was lost in iTunes (de-selected songs, playlists, rankings, play counts) and iPhoto (geotags, names, etc). Any ideas / help? I sank considerable time into my music and photos and would love to have that time back.
FWIW, I'm in the process of buying an external hard drive as a secondary backup to the TC as my confidence is a little shaken on the product line - the first time I ever actually need a backup and the backup is unmountable. My whole point of spending a little more and buying into the Apple ecosystem for a backup solution was to streamline the backup process and avoid these types of issues.

Thank you for the reply. I tried the Disk Utility to repair my TC's Time Machine backup disk with no luck, it stopped with the message:
Disk utility stopped repairing "iMac"
Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
It took a night but I was able to copy all the TC Time Machine files to the external hard drive as a backup to a backup just in case. I'm still pretty bummed the TC's backup didn't allow for Disk Utility's restore functionality. Fortunately, the iPhoto library backup I dragged to the iMac from the Time Capsule backup worked without a hitch. On the downside, the "iTunes Library.itl" backup I dragged over is locked so now I'm checking out the forums for any ways to fix that. I temporarily created a new iTunes library with all my apps and music but plan on reverting to the old iTunes library if possible so I can start syncing my iOS devices again.

In migrating to a 21.3" iMac from a Time Machine backup, can I do this more than once?
