>As Craig mentioned, VSS does not use SQL Server. There is a product (Vault) that does use SQL Server to store the files:

I have been using the vault for 6 + months now and find it easy to use and solid. I like the fact that I can BACK IT UP. And restore from it if I have to. Had a VSS system that crapped out. Got p-Offed and found Vault instead.
Vault is slower then VSS in starting up. But it's great after that initial lag.
Vault does a good job in getting my diff between what was saved and what I've done to screw it up :)
