SFW provides support for taking VSS COW snapshots of Microsoft SQL databases. FlashSnap integrates with the Microsoft Volume Shadow Copy Service (VSS) to allow snapshots to be taken of all volumes that are associated with an SQL database without taking the database offline. The VSS COW Snapshot wizard uses VSS to take snapshots of the database. The VSS process allows the database to be quiesced before the snapshot operation and reactivates it immediately after.

SFW also provides a VSS COW Snapshot Scheduler wizard that can be used as an alternative to the VSS COW Snapshot wizard. It enables you to set up a schedule for taking the snapshots. The schedule is maintained by a scheduler service, VxSchedService.exe, that runs in the background.
