Time Machine - An error occurred while restoring from the backup
Having some trouble restoring a Time Machine backup. After some initial disk problems we had to reinstall OSX and this is what has been done thus far:
- Booted into Internet Recovery Mode (Command (⌘) – Option (⌥) – R)
- Reinstalled OSX
- Rebooted and into Recovery Mode (Option (⌥) – R)
- Selected to Restore from the Time Machine Backup
- Restore goes fine for 6+ hours (91%) and then fails with the message, "An error occurred while restoring from the backup. Restart your computer, and then try again"
- I tried an older backup from the same sparse bundle but having the same problem.
I have tried this three times but it fails in the same location each time. Any suggestions at this point would be Welcome.
Solution 1:
Basically you have to explore what's going wrong and fix it manually.
Hope this helps:
Inspect the installer 'Log' and if you have a 'Critical failure' pertaining to a particular folder(s), proceed with these steps:
Connect your backup to a working Mac (or fresh install MacOS on the Mac you're trying to restore to)
Open Terminal and mount the Time Capsule's sparse bundle (if using a Capsule rather than a USB/network drive).
In Terminal, use TMSafetyNet.kext to remove the troublesome folders one by one.
Return to Recovery Mode on the target machine and restore with the fixed backup.
