Select how snapshots are made for the selected clients:

• Individual drive snapshot

  Specifies that the snapshot should be of an individual drive (default). When this property is enabled, snapshot creation and file backup are done sequentially on a per volume basis. For example, assume that drives C and D are to be backed up.

  If the Individual drive snapshot property is selected, NetBackup takes a snapshot of drive C, backs it up, and discards the snapshot. It then takes a snapshot of drive D, backs it up, and discards the snapshot.

  Volume snapshots are enabled on only one drive at a time, depending on which drive is to be backed up. This mode is useful when relationships do not have to be maintained between files on the different drives.

  Use this configuration if snapshot creation fails when all volumes for the backup are snapshot at once when the Global drive snapshot property is enabled. Individual drive snapshot is enabled by default for all non-multistreamed backups by using the Windows Open File Backup option.

• Global drive snapshot

  The property specifies that the snapshot is of a global drive. All the volumes that require snapshots for the backup job (or stream group for multistreamed backups) are taken at one time.

  For example, assume that drives C and D are to be backed up.

  In this situation, NetBackup takes a snapshot of C and D. Then NetBackup backs up Cand backs up D.

  NetBackup then discards the C and D snapshots.

  This property maintains file consistency between files in different volumes. The backup uses the same snapshot that is taken at a point in time for all volumes in the backup.

  Note:

  The Individual drive snapshot property and the Global drive snapshot property only apply to non-multistreamed backups that use Windows Open File Backup. All multistreamed backup jobs share the same volumes snapshots for the volumes in the multistreamed policy. The volume snapshots are taken in a global fashion.
