How to repair a Time Machine drive?

Once you have recovered Time Machine backup, you can go ahead and repair the drive using First Aid by following the steps below.

As a first step, turn Time Machine off. To do this, go to Apple menu > System Preferences > Time Machine > Turn off

You will then use the First Aid feature available in Disk Utility to repair the drive.

  1. On the dock, click on Finder > Applications > Utilities
  2. Then select Disk Utility
  3. In the left sidebar, all volumes are listed. Select the Time Machine drive

If you receive a message that the drive appears to be Ok, the drive has been repaired and you’re good.

If First Aid reports an error ‘Overlapped extent allocation’, it indicates that multiple files occupy the same place on the drive. There is a possibility that these files could be corrupt. You will need to evaluate these files in the DamagedFiles folder that Disk Utility has created. Deleting the file will help resolve the issue. (If the file is important, you can also recreate the file easily prior to deletion).

However, if you receive an error ‘The underlying task reported failure’, run First Aid multiple times to see if the issue can be fixed. If it doesn’t work, it is best to backup data if, format and create a new Time Machine backup.
