Problem
Documentation: How to override the default hardware VSS snapshot provider in order to use a software counterpart on a Windows 2003 based computer.
Solution
If you have more than one VSS provider registered on a Windows Server 2003-based computer, the Volume Shadow Copy Service tries to start the providers in the following order:
1. Hardware provider
2. Software provider
3. System provider
However, if the hardware provider cannot be started for some reason, the NetBackup cannot perform a shadow copy components/system state backup as expected.
To resolve this problem, generate a list of providers that are installed on the system. To do this, run the following command at a command prompt:
1. Hardware provider
2. Software provider
3. System provider
However, if the hardware provider cannot be started for some reason, the NetBackup cannot perform a shadow copy components/system state backup as expected.
To resolve this problem, generate a list of providers that are installed on the system. To do this, run the following command at a command prompt:
vssadmin list providers
This command generates the following output:
Provider name: 'Microsoft Software Shadow Copy provider 1.0'
Provider type: System
Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}
Version: 1.0.0.7
Note: This is the default output only if the in-box Volume Shadow Copy Service system provider is installed. You may see additional providers.
To modify the above behavior a registry edit is required
1. Click Start, click Run, type regedit , and then click OK.
2. Locate the following registry subkey, and then right-click it:
HKey_Local_Machine\SYSTEM\CurrentControlSet\Control\BackupRestore
3. Point to New, and then click DWORD Value.
4. Type UseMicrosoftProvider as the name for the new DWORD value, and then press ENTER.
5. Double-click UseMicrosoftProvider. To enable the new feature, type 1 in the Value box. To disable the new feature, type 0 in the Value box.
6. Press ENTER, and then exit Registry Editor.
7. Restart the server.
8. Use NetBackup to perform a shadow copy components/system state backup.
Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
