Transini Level 1 Level 1 (135 points)

OSX 10.6.8, iMac, external 3 TB user account drive, external 2 TB TM drive.

 

I just FileVaulted the external 3 TB drive on which my user account resides.

Now when I try to run TM to an empty 2TB drive, it gives me this error message:

 

------------------------------------------------------------------------

Time Machine could not complete the backup.

 

This backup is too large for the backup disk. The backup

requires 4.51 TB but only 2.00 TB are available.

------------------------------------------------------------------------

 

Note the df command output below. The external account drive now has 2 mount points.

The FileVault mount shows 5.85 TB --- on a 3 TB drive, go figure!

When I issue a du -s on my account, it comes back with only 573 GB used.

 

$ df -k

Is there some way to reset TM or overcome this glitch?
