ERR - Unable to backup System State or Shadow Copy

Hi guys!

Thanks for the info! 

I manually specified a VSS provider on the client machine by this command:

w2koption.exe -backup -snapshotprovidertype 1

then I ran a backup on the Master server and It backed up successfully!

Cause:

When backing up a windows 2003, the VSS provider must be a Microsoft Software Shadowss Copy by default

If you have more than one provider registered on a Windows Server 2003-based computer. the Microsoft Software Shadow Copy Provider (a.k.a. the System Provider) will likely not be used by default and that causes an error

Solution:

In the NetBackup version 7.1 and higher client , there is a w2koption command to force NetBackup to use a manually specified provider.

The 'w2koption' command located in the ....netbackup\bin\  directory provides functionality to force the NBU Client to use a particular provider type.

w2koption -backup -snapshotprovidertype <0, 1, 2, 3> 

0   (Let Microsoft Windows decide which provider to use)
1   (Selects System VSS provider)
2   (Selects Software VSS provider)
3   (Selects Hardware VSS provider)

Example to configure NBU to use the System Provider:
     w2koption -backup -snapshotprovidertype 1
