10.5: Reconnect Time Machine backup after drive swap
Authored by: rkusa on Dec 11, '09 09:47:21PM

I have not been able to get this to work at all. I feel like I must be missing something. When I try the command to display the UUID from the Time Machine backup, I either get a reply like -bash $ command not found or something like that. So I've tried, on command lines where my admin account name is followed by a $, to just start the command leaving out the $. That gives me various results. Mostly I get nothing.

To get the paths to the partitions or drives, I've been dragging the icon into TextEdit so it fills in the path for me, copying and pasting it into the command given in the example.

I never could get any UUID to display from the command line. I found the Time Machine and the new source drive UUIDs from Disk Utility Info.

I pasted into Terminal the ACL command to disable,

then I pasted the new drive's UUID into the command to change the UUID,

then pasted that command for changing the UUID into Terminal,

then pasted in the ACL command into Terminal to reenable.

I hit Return after inserting each command. In each case, there was no response in Terminal after each action just a > symbol. I tried the alternate (corrected) command posted by markauk, and got a string of not found errors for each backed up volume on TM plus Shared and a couple of other things.

I also tried the script that someone referred to, and it gave me a reply that my drives are already paired, but I know that's not true because it keeps wanting to do a complete backup from scratch.

I hope someone here can tell me what I might be missing in this whole thing. BTW, I'm using 10.5.8. Any help will be greatly appreciated.

10.5: Reconnect Time Machine backup after drive swap

You need both command-line tools to get this done: xattr and fsaclctl You can check for their presence with these commands:

sudo which xattr

sudo which fsaclctl

If either of these is not found, you'll need to get it first.

fsaclctl is no longer part of the system under 10.6, so it must be restored from a 10.5 backup; But it is a bit crude anyway when I've got some spare time I may check out the proper way of removing and restoring the extended attributes for each file individually.

There are no problems...
