Completely new Time Machine backup? I made use of Time Machine to restore my Mac's OS and data to a new drive after the old one failed. Time Machine doesn't seem to recognize that the new drive and the back ups are related. Is there a method to connect the two, or do I need to wipe that drive containing the old history, and just start a new TM backup?
The Time Machine backups became disassociated with the new drive because of the change to the UUID of the new drive. With a little usage of tmutil in Terminal following the directions here, you can rebuild the association of the Time Machine backups to the new drive.
