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 :-(((

  • 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.

  • How do I move time machine files from one external drive to another?

    My original external drive isn't big enough. So I've bought a second larger one. How do I move the earlier Time Machine backups from Ext Drive #1 to Ext Drive #2 so I can access my full history, and leave Drive #1 for other backup items?
    Ext Drive #1= SimpleTech 120 GB
    Ext Drive #2= WEstern 500 GB

    When you are ready to pass the 320GB drive on, I would format it. That will make the entire drive available to him to use as his TM. I would be sure that each drive has a unique name so that there will be no confusion for TM as to which computer goes with which drive. If you want to start fresh with the 500GB drive, I'd format it as mac-extended-journaled. When you connect it the first time to your computer, you will be asked if you want to use it as your TM. If you are not prompted to select it as your TM, you can configure TM by opening system preferences, click on TM, click on "change drive" and choose your new drive.
    Another choice is to follow the steps in my previous response for restoring your current TM to the new drive by booting from a Leopard start up disk and accessing Disk Utilities from there so you can restore the drive. It is essential that the new hard drive is the exact name as the old TM hard drive. In this last scenario you would continue adding to your current set of backups.

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

    my time machine file is about 390GB and it is on a 1TB external harddrive. I have been trying to move the backup to a new 2TB external harddrive. it stopped copying any more files after transferring 466MB. I repeated the same procedure several times,but with same result. any advice? thanks!

  • Multiple Time Machine backups to one external drive

    I have a MacPro with an external hard drive that I use exclusively for Time Machine (the external drive is mirrored RAID).
    I now have a MacBook Pro as well. Can I set the Time Machine on the laptop to backup to the same external hard drive that I currently use for my desktop? When I look at the Time Machine set up on the laptop I can see the desktop's external drive but don't know if I can have Time Machine backups from two different computers writing to the same external drive.
    Thank you

    yes you can do that. this is a supported configuration. although it's better to keep TM backups for different drives on separate partitions. probably not an option here though. the remote backups will be stored in a sparse bundle. while remote ones are stored directly in a folder on the drive.

  • 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.

  • Time Machine - Backup from One Ext HD to Another Ext HD?

    I'm sure this has been asked before but my searches have come up empty.
    I'm currently setup on a 27" iMac (about 18 months old) and currently using Time Machine to backup my internal hard drive to an external raid setup.  However, I keep all of my media files on an external hard drive rather than take up much needed real estate on my internal HD.
    My question - is there anyway thru Time Machine to backup my external media drive to another extrnal drive, which is part of my raid setup?  All externals are hooked up to the iMac and the iMac is recognizing all drives.
    Or is Time machine limited in nature to only allow copying/backup from the internal drive to some other peripheral drive?
    Thanks!!

    Time Machine can back up from multiple volumes, but only to a single volume.  
    Internal volumes are backed-up by default; external volumes are excluded by default.  Go to Time Machine Prefs > Options.  The external should be listed in the exclusions box there.  If it's shown in black, just select it and click the minus sign at the bottom.   It will be included on the next backup.
    If it's listed in gray, however, it's not formatted HFS+ (any variation of Mac OS Extended), Time Machine can't back it up, and you can't remove it.
    If there isn't room on your external, and you can't expand the partition your backups are on, you'll need a different app, such as CarbonCopyCloner or SuperDuper.

  • 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.

  • Transfer Time Machine Backup To A New Drive

    Can I transfer my TM backup from one external drive to another external drive, both drives wired, or do I need to start over with the new drive? I own SuperDuper.

    just clone the old TM drive to the new one using Superduper.

  • I had to reformat my OSX 10.5.8 and i can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help

    I had to reformat my OSX 10.5.8 and I can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help? I can find the mail folder in my libraries, but the Restore Button is grayed out

    OSX treats the reformatted drive as a different one; it's the same as replacing it, and the old one is no longer connected.
    See #E3 in  Time Machine - Troubleshooting to see and restore from the "old" drive.
    And, you may not want to restore via the Finder; see the blue box in #15 of  Time Machine - Frequently Asked Questions.

  • Is there a way to get my photos off an old time machine backup from an external hard drive?

    Is there a way to get my photos off an old time machine backup from an external hard drive?

    You will have to connect the Time Machine HDD and click on the Icon.  You will see one folder called Backups.backupdb.  Click on that and you will have to continue until you find the home folder.  The iPhoto library (where the pictures are, not the application) will probably be in your pictures folder.  You will have to drag that to your desk top.  Then you will have access to individual images.
    Ciao.

  • I threw out 24 time machine backups from an external hard drive into my desktop trash and now I can't empty my trash.

    I threw out 24 time machine backups from an external hard drive into my IMac desktop trash and now I can't empty my trash.

    Since you didn't mention what type of error message you were seeing, I'm going to guess on what is happening.
    I'm guessing that since you threw away Time Machine backups, that Time Machine is probably active on your Mac. There is a chance then that the files you tossed are marked as in use. You can't delete files that are in use.
    Try turning Time Machine off, then restart your Mac. Then try deleting them again.
    Once done, turn Time Machine back on.

  • Time machine backup with 2 external drives?

    i got myself an external hard drive to use with my MBP. I do a lot of filmwork in imovie for my artwork, and have found my internal hard drive filling up fast.
    So i bought a second hard drive yesterday. I'm hoping to backup my files on the external drives so i can erase the files on my MBP and keep it fairly free to record more film.
    Is there a way to simultaneously backup to both external drives? or to move files from one external drive to another quickly? I am a complete newbie to macs (and technology for that matter) so simple words work best smile
    thanks!

    Hello
    Does anyone know if it's possible to use two separate external drives in Time Machine to backup different parts of my mbp hard drive? That is, I want to use ex.drive1 to back up work files at work and ex.drive2 to back up personal files at home. In time machine options, I can set the folders for exclusion, but currently have to set those each time I back up at home/work.
    There's no easy way to do that with Time Machine. As you see, it only has one set of exclusions and one destination drive at a time.
    In theory, and if you're careful, you might be able to manipulate the preference file where all that's stored. Set TM up for home, say, then copy or rename that version. Then set it up for work and do the same.
    The file is at the top level of your drive, not in your home folder:
    /Library/Preferences/com.apple.TimeMachine.plist
    You could probably write an Automator workflow or AppleScript to simplify swapping the files.
    Otherwise, two alternatives:
    Back up everything in both places.
    Use Time Machine at home, and a different app, such as CarbonCopyCloner or SuperDuper, at work, or vice-versa.

  • I've mistakenly deleted Time Machine backups from my external HDD. How do I fix this?!

    I manually deleted several Time Machine backups from my external HDD. Whenever I attempt to empty trash, it states (error code -22) has occurred. How do I fix my predicament?
    I understand (now) that I should never do this and ONLY delete from the Time Machine app itself but I did not assume this would be so complex by taking a blind stab at it. How do I either a) place the Time Machine backups where the originated (Put Back is not an option when right-clicked) or b) successfully delete these so I can clear my bin.
    I am running Mac OS 10.10 on a 13" MacBook Air (mid-2013) w/ 4GB of RAM and 128GB SSD. My external drive is a 5400 RPM WD USB 2.0 External Hard Drive.
