Snapshot Provider

Select the snapshot provider for the selected clients:

Use Veritas Volume Snapshot Provider (VSP)

This option specifies that Veritas VSP be used as the snapshot provider. VSP is required for Windows 2000 clients and can also be used on 6.x Windows 2003 clients.
Use Microsoft Volume Shadow Copy Service (VSS)

This option specifies that Microsoft VSS be used to create volume snapshots of volumes and logical drives for the selected clients.

In 7.0, Microsoft VSS should be selected for all Windows clients, as VSP is not available. VSS is available for all supported Windows clients, XP SP2 and later.

Configure VSS through the Microsoft VSS configuration dialog boxes.

For information about performing Active Directory granular restores when using VSS, see the following topic:
