View Full Version : Restore using SD - now TM recopying everything

04-14-2008, 01:54 AM
I just upgraded the drive in my MacBook Pro. I had been using Time Machine via an Airport Extreme Base Station. Before doing the switch I turned off TM using the preference panel and then made a bootable backup using SuperDuper. With the new drive in, I booted from the SD backup via Firewire. I then did a complete copy to the new internal drive.

Rebooting from the new drive was good - everything worked fine. I then turned TM back on, expecting a short backup to occur. But TM thought that every file had changed and seemed to be recopying everything to the original backup set. It was not doing an "initial backup" which creates a new backup set and shows a progress window. It was just updating every file in the original set.

Why did it do this? It seems to me that SD is doing something to files or folders such that the restored copy is not exactly the same as the original? Any ideas?

The drive itself is different, so the backup is likely to be re-copied just like this...
