Dell Replay Manager Version 7.8 Administrator’s Guide

VSS for Shared Folders

VSS for Shared Folders, a similar technology built into Windows, provides the ability to back up a volume which in turn stores the shadow copy on the volume itself in a hidden location. By default, snapshots in VSS for Shared Folders take place at 7:00 a.m. and 12:00 p.m., and shadow copies are replaced as required by the amount of free disk space on the volume. The snapshot times can be adjusted, but the snapshots should run no more than once every 60 minutes.

Using VSS for Shared Folders and Replay Manager on the same volumes is not recommended as this combination uses additional disk space because VSS stores the deltas (data changes or differences) hidden on the volume while Storage Center determines which blocks to freeze. This is essentially duplicating efforts on the volume.
