> Along that line my backup scheduler kicks off all the backups at once, meaning if I have 5 databases they all get shelled off at once including the security database. I wonder if there is a thread safty issue and part of the backup file is getting corrupted by another DB's backup such as the security datase somehow data flowing into backup file.

You are right, this is suspicious.
Let me clarify: you do all backups at the same time, using services,
right? And you use superserver, so all backup threads share the same
address space.
