I mentioned the big one - it's vss/block based instead of file based. The major thing this means is that (just like a tape), you hand off an entire drive (or two or three...however many you need to maintain your rotation and generational coverage) to WSB and it manages the contents. You don't touch the drive as a filesystem. All of your access to the drive (just like a tape) is through the backup media.
However, you can have dozens/hundreds of generations of a file on a single backup drive. Because the backup is block based - just like VSS. It takes snapshots and copies the differential snapshot (more or less). It isn't file based. The higher your disk "churn" the fewer generations you can store on a given drive. For most of my smaller (read that as: SBS) clients, I have two 1 TB drives, one onsite and one offsite and I rotate them weekly. This is one of the backup options that Microsoft DPM has, and I know recent versions of BackupExec/NetBackup support it too. Regards, Michael B.

It works surprisingly well. (WSB is MUCH smarter than you may think - it does require you think a bit differently than you are used to doing - because the backups are VSS/block based, not file based.) Regards, Michael B.
