Backup Exec…Ughhh

Greetings!

Win2K Server
Backup Exec, Version: 8.50, Revision: 3572

I have had no issues with backups for the past several months.

Recently, the backup completes, but at the end I get the following:

======================================================================
Job ended: Saturday, January 20, 2007 at 3:17:25 AM
Job completion status: Aborted by SERVER\.
======================================================================

The tape is then ejected.

Nothing in the configuration of Backup Exec has changed. Only my boss and I have access to the server and neither of us have changed anything.

Any suggestions would be welcome.

Thanks in advance!
