Hi there

I have been having the same problem (since I upgraded to a dual band AE) - TM fails with an error message "The backup was not performed because an error occurred while copying files to the backup disk" I haven't been able to complete a back up since a day after I installed the new AE.

Thanks in advance for any help or advice.
