When the Veritas Volume Shadow Copy Service (VxVSS) provider is registered with the Microsoft Volume Shadow Copy Service (VSS), backup software may use VxVSS instead of the standard Microsoft Software Shadow Copy provider.
VxVSSProvider.exe can be used to register or unregister VxVSS with VSS (Figure 1).
Figure 1 - VxVSSProvider Commands
| Command | Description |
|---|---|
| vxvssprovider /service | Registers the Veritas provider from VSS |
| vxvssprovider /unregserver | Unregisters the Veritas provider from VSS |
| vssadmin list providers | Lists the providers that are registered with VSS (Figure 2) |
