10.5: Reconnect Time Machine backup after drive swap
HD in my iMac failed - saw it coming, and was able to CCC the drive before it died. Apple replaced it under AppleCare, and I then CCC'd my data back, only to run into the full backup problem everyone here has had. I've had no luck connecting to my backup drive, which is in a Time Capsule, using Terminal and the steps outlined here. Weirdly, I can mount the sparsebundle to my desk top, and can see the virtual drive in Disk Utility, so I can see the UUID of the backup and the UUID of the new drive. I wish I had been clever enough to have restored the new drive from the Time Machine backup, but I wasn't, and now there is too much new info on the replaced drive.

I don't have a Time Capsule, so I cannot say much about the details. ---
There are no problems...

Thanks for this.

I can't be certain, but I would also expect CCC to leave the UUID alone, so in case you needed to restore the backup with CCC, you might have to revert the UUID as well (be sure to make a separate note of the original UUID on the backup drive before changing it on the system drive).
I would also recommend you to make the fresh backup to a different drive than the original CCC one if at all possible. I know I sound paranoid, but that is only proper when dealing with the entirety of your data. Don't Panic! — But nevertheless be cautious! 8-) ---

Now I have to confess to being Terminally illiterate. So:

- do I boot from a different volume when I attempt to change the UUID on my normal boot drive, or can I do it while booted from that volume?
That is probably a good idea in order to avoid potential confusion, although it should not be absolutely necessary. If you do it while running from that same volume, just be sure to complete the change and then restart the system right away so the change will take effect. - what is the full path to the root of a boot drive? Just / . All other volumes are mounted under /Volumes/ . You can find the path by simply dropping a file, folder or even a drive into a Terminal window: The respective path is then automatically inserted into the current input line. - do I need to log in as root admin, or can I log in via my usual user account? Calling the respective functions via sudo already takes care of that (your account must be enabled as an admin account for this, and you will be asked for your password on execution). But there is no need to explicitly log in as root. - is there an easier way to change this UUID? Not to my knowledge. Normally it is not supposed to be done, so it shouldn't be easy, really. ;-) I've searched extensively and haven't found references to any of this online - is there a reference book or source, no matter how wonky, that I can but? I'm not aware of a book (which could well exist), but for some of the background the articles by John Siracusa on ars technica about Mac OS X are quite interesting. Thanks so much for tolerating me. I can make a dozen major apps dance and sing, but Terminal is NOT one of them.
No problem – I always recommend anyone to be careful about treading unfamiliar ground, but I'll try to help where I can. :-)--- --- There are no problems... Edited on Mar 27, '10 04:56:34AM by only_solutions
