When running one of my daily backups, I get this error every day:

Job ended: Wednesday, October 07, 2009 at 11:18:29 AM
Completed status: Failed
Final error: 0xe0008442 - A memory allocation request failed. The computer may be running low on virtual memory.
Final error category: System Errors

I've seen other cases where a restore caused this error, but this is a backup. I've increased virtual memory considerably (on both the target and the Backup Exec Server) and I still have the same problem.

The backup selection list includes Exchange server 2007, SQL, Sharepoint as well as files and folders. Any suggestions?
