About VSS
VSS uses the Volume Shadow Copy Service of Microsoft Windows and supports Instant Recovery. VSS is for local backup or alternate client backup.
For the most up-to-date list of Windows operating systems and disk arrays supported by this method, see the NetBackup 7.x Snapshot Client Compatibility List document available on the Veritas support site:
http://www.netbackup.com/compatibility
For alternate client backup, the client data must reside on either a disk array such as EMC, HP, or Hitachi with snapshot capability, or a Veritas Storage Foundation for Windows 4.1 or later volume with snapshots enabled. VSS supports file system backup of a disk partition (such as E:\) and backup of databases.
Note:
VSS-based snapshot methods offer a general interface to Windows Shadow Copy Services. VSS selects the actual snapshot method depending on which snapshot provider is configured on the client. For instance, if the data resides on an EMC CLARiiON array and the array administrator configured the array and its snapshot capability, the Volume Shadow Copy Service selects the appropriate CLARiiON VSS hardware provider to take the snapshot.
For configuration assistance, refer to your Microsoft documentation.
