Recently got a repaired MBP back, Time Machine won't recognize old backup

[peppermints]

Hello all.

I got my MBP back yesterday from a logicboard replacement. I tried doing a backup today, and it failed multiple times - wouldn't even get started "preparing". I then attempted to enter Time Machine, and there was nothing there. I double checked to see if the actual backup data was still on my HDD, and sure enough it was.

So I then repaired the drive with Disk Utility. Now I am able to backup- but not in the same backup as my previous Time Machine. They're now listed as "____ Computer" (original) and "____ Computer 2", both in the "Backups.backupdb" folder.

Any idea why it's not recognizing the other backup and what I can do to fix it?

i'm pretty sure you're backing up via network, right?

new logic board comes with a new MAC address, so as far as network timemeachine backups are concerned, you have a different machine.

if you rename the old sparse disk bundle's name to the new one and trash the new one, it should work.

I'm actually using an external HDD. Would that be the same process?
