Modifying the VSS Provider for Backups (Microsoft Hyper-V)
By default, the backups use the software Volume Shadow Service (VSS) provider from Microsoft.
You can configure backups to use the hardware VSS provider offered by other storage vendors. Using a hardware VSS Provider can improve the performance of backup operations. For Hyper-V clusters, it reduces the amount of time that cluster shared volumes (CSV) are caught in redirected-access mode.
Before You Begin
Identify the VSS provider ID of the vendor.
To find the ID, on your Hyper-V host, at the command line prompt, run the following command:
vssadmin list providers
An example of a provider ID (for NetApp) is ddd3d232-a96f-4ac5-8f7b-250fd91fd102.
To use the vendor's VSS provider ID
- On the Hyper-V host, configure the VSSProvider additional setting .
For instructions on configuring an additional setting, see Add or Modify an Additional Setting.
Provide the following inputs during the configuration:
- Name: VSSProvider
- Category: Default: VirtualServer
- Type: Default: STRING
- Value: The VSS Provider ID of the vendor
Subsequent backup operations will use the newly configured VSS Provider.
