Switching Time Machine drives easy but not quick

maxtor-1Back in December, 2007, when I upgraded my super-duper 24″ iMac to Mac OS X 10.5, I immediately turned on the Time Machine automatic backup program. Seeing as how I had a less-than-half-full 500 GB hard drive in the iMac, I figured I’d be fine using a 500 GB Western Digital MyBook Pro external drive for backup. The Western Digital had a Firewire 800 connection, so back-ups were super fast.

Of course, over time,Time Machine stored more and more stuff that had been changed or deleted and the Western Digital drive got pretty full. So it wasn’t too hard to locate a gigantic upgrade, a 2TB — yes that’s T for terrabyte — Maxtor external drive on sale at Frye’s online web store. It’s not the very latest model, a OneTouch III Turbo Edition, but it has Firewire 800 and 400 ports along with a USB 2.0 connection. I figured that 2 terrabytes out to hold enough backups for some decades to come. We’ll see about that.

Buying the drive was the easy part, though. The harder part was figuring out how to get my Time Machine backups onto the new drive so that my computer would recognize them and keep on building onto the same set. Otherwise, if I’d started fresh, I’d have lost the last year’s worth of cool Time Machine backups of files I’ve since changed or deleted.

The answer, on this tips page, proved to be simple but time consuming. First, I turned Time Machine off. Then I attached the new Maxtor drive to my iMac while the old Western Digital drive was still also attached. Then I opened Disk Utility, clicked on the new disk in the list and clicked on the “restore” tab. Then it was a simple matter of dragging the Western Digital drive icon (where the old Time Machine backups were saved) onto the “Source” box and the icon for the new Maxtor drive onto the “Destination” box. I hit restore and ta-da — everything was cloned automagically onto the new drive, which also got named the same name as the old drive. Only one catch: IT TOOK SEVEN HOURS. I have no idea why but it did.

Once the cloning was complete, I dismounted the old drive, turned Time Machine back on and it continued merrily on its way as if it didn’t even know about the disk swap. Cool if time consuming!

The Maxtor OneTouch III drive is considerably heavier and thicker than the old Western Digital MyBook Pro drive, no surprise since it’s quadruple the capacity. But it’s also much noisier when in operation and for a while afterwards, until it winds down into silent sleep mode. That’s a drag in my little home office but what can you do? Anyone know how to change the sleep settings on an external Maxtor drive?

    I'm glad it worked out for you! I've moved my Time Machine set twice since I wrote that article, actually, and am happily working with a 500 GB drive like your old one!

    It's the RAW-format photo files that are killing me! But the end
    results can't be beat with Lightroom, so I'm doomed to using ever-
    greater storage capacity, I guess. Thanks again for the tip.

    The weight, size, & noise are probably because it's a two-drive model. Be careful, these are basically RAID-0 in a box.. if one of the two drives fails you lose the entire array. I've seen it happen with the LaCie “Bigger Disk” drives.

    Aaron,
    Good post. I'm in the midst of moving and consolidating everything onto a WD MyBookWorld. Not sure of your thoughts, but I am concerned now that all my media and backups are converging on one device, about “how to backup the backup”. Any thoughts on online storage services?

    I have had a great online backup experience with Mozy – been using it
    for almost 2 year now. For the amount of data I have backed up (almost
    150 GB — which includes media files and RAW photo images), it's
    cheaper than Amazon S3 and the backup software is simple and reliable.
    Plenty of encryption as well (and the truly paranoid can encrypt with
    their own key). I also like that it's owned by EMC, a solid company
    where backup services are a core product offering.

    I blogged about my experiences with Mozy in more detail in December (https://gravitationalpull.net/wp/?p=553
    ) and April (https://gravitationalpull.net/wp/?p=279) last year.

    I also do a once-a-year burn everything important to DVDs and send
    them to my brother in Connecticut for my redundant offsite backup.
    Maybe I should start leaving a 2nd copy at my mother-in-law's in
    Osterville in case a freak volcano takes out West Hartford?

    I have tried 4 times to get this to work. First three came up with “Could not Restore. Operation not permitted”. I went back and reformatted the destination HD. This time though I formatted both the mounted volume and the disk image. It went through the whole process and then came up with “Could not restore – Cannot allocate memory”. I have the log report and snapshots of the DU screens. Can you help me?
