I installed DPM 2007 on server 2008 64bit with a Quantum Superloader 3 which 
has a LTO 3 tape drive and space for 16 tapes. When I tested a backup I was 
able to backup a SQL database from another server without a problem. However, 
every single backup since then has failed with the same error:

Type:	Tape backup

Drive. (ID 30101 Details: The request could not be performed because of an
