To echo Poots, a maintenance plan is better than nothing. It isn't what I'd like, but it is still much better than nothing.
Based on what Desiree is describing in BackupExec, I'd bet that she doesn't have any usable backup of her SQL files. Based on that, I'd bet that there isn't a usable backup for Exchange or any other server tools either. That's a frightening thought to me.
Desiree: You need to figure out what you have and what you don't pretty quickly. I literally could not sleep if I didn't have good backups, and we don't know what you've got. I think this needs to be your top priority, over and above anything besides bodily functions until you get something backed up and off site.
