Off Topic: is Backup Assist still your choice for network backups and such?
Personally, I just use wbadmin from the command line. It seems like backup assist is just passing arguments to that program. But I know how to backup and restore from the command line. Backup assist provides a nice GUI to manage those backups and restores. I wouldn't recommend using the command line unless you know what you're doing. You also don't get a lot of the features of backup assist.
Backup assist is great though. Provides a central interface for tracking backups as well as a simple user interface for creating and restoring them. I highly recommend it.
