Time Machine & Restored iMac

[DisneyRicky]

I just restored my iMac after hard drive failure via Time Machine. However, it's state was not fully backed up, so I restored to my MacBook Air. No big deal, since I was able to pull over all my files from an old archive of my computer.

With this done, now I want to start doing Time Machine backups once again, but am faced with an error when I do so. How can I force Time Machine to make a new database for this new computer?

I believe at this point you should have two options:

1) Turn on Time Machine and tell it to use the current disk. This will allow you to just continue on.

2) Start over by using Erase Disk on your TM drive and then turn on Time Machine.

It has been a while but I was in the same boat as you a while back. I used option 1 as I recall.

If your data is all safe, I'd erase the TC and start again.

Check in System Preferences > Sharing and see if the Computer Name is the same as the Air's. That may be where the error is at as its trying to duplicate the process.

Try renaming it and creating a new back-up.
