Use Replication Director (policy attributes)

Enable the Use Replication Director attribute when configuring a backup policy for Replication Director. By enabling this policy attribute, NetBackup enables other policy attributes that Replication Director requires:

  • Perform snapshot backups

    Ensures that the policy creates snapshots of the disk array.

  • Retain snapshots for Instant Recovery or SLP management

    Ensures that the policy retains the snapshot after the backup completes.

  • Perform off-host backup

    This option is selected automatically for an NDMP policy, along with the following selections:

    • To use Data Mover

    • NDMP as the Machine selection.

  • Replication Director Options

    Click the Options button to see the Replication Director Options dialog box and the default Configuration Parameters as follows:

    Snapshot Type

    • Auto (default): The OpenStorage partner uses the best snapshot technology available to that partner to create the snapshot.

    • Differential: The OpenStorage partner creates a snapshot that is completely dependent on the source. This parameter is based on copy-on-write technology. The device creates a cache object to maintain the original blocks of the snapshot when the blocks are modified.

    • Plex: The OpenStorage Partner creates a snapshot that is completely independent of the source snapshot. This option is based on mirror-break-off technology. When a mirror device is attached to the source, the contents of the mirror device is exactly the same as the source device. When the relationship is broken between the two, the mirror device is separated from the source. The mirror device acts as a point-in-time copy.

    • Clone: The OpenStorage Partner creates an independent copy of the volume. The copy process can take some time as the entire copy must be complete. The snapshot that is created is independent of the source.

    Maximum Snapshots

    Sets the maximum number of Instant Recovery snapshots to be retained at one time. When the maximum is reached, snapshot rotation occurs: The next snapshot causes the oldest to be deleted.

    Managed by SLP retention is automatically selected if the Fixed or the Expire after Copy retention is currently selected in the SLP.
