VSS restore command-line considerations

Refer to the following considerations when performing VSS restores. Unless otherwise specified, VSS restores refers to all restore types that use VSS (VSS restore, VSS fast restore, VSS instant restore):

• A VSS instant restore overwrites the entire contents of the source volumes. However, you can avoid overwriting the source volumes by specifying /instantrestore=no. This parameter setting bypasses volume-level copy and uses file-level copy instead to restore the files from a VSS backup that resides on local shadow volumes. The source volume contains only the SQL Server database.
• When a VSS restore from local shadow volumes is completed, the bytes transferred is displayed as 0. This value is displayed because no data (0) is restored from the Tivoli® Storage Manager server.
• To perform a VSS instant restore with versions of the Tivoli Storage Manager Backup-Archive Client earlier than 6.1.0, the Tivoli Storage Manager for FlashCopy® Manager Hardware Devices Snapshot Integration Module must be installed.
• When performing VSS instant restores, you must make sure that any previous background copies that involve the volumes being restored are completed prior to initiating the VSS instant restore.
