This option specifies whether or not the snapshot image is retained on the mirror disk after the backup completes (default is No). Retaining the image (Yes) enables a quick restore from the mirror in case data is deleted from the client's primary disk. The image is retained on the mirror until the next time a backup is run using this policy. No indicates that the image is deleted from the mirror as soon as the backup completes.

If the client is rebooted, the snapshots that have been kept must be remounted before they can be used for a restore. You can use the bpfis command to discover the images.

See the bpfis man page or the NetBackup Commands manual.

Note however that NetBackup automatically remounts Instant Recovery snapshots.

If the snapshot is on an EMC, Hitachi, or HP disk array, and you want to use hardware-level restore, important information is available.

See the Warning under "Hardware-level disk restore" in the NetBackup Snapshot Client Configuration document. This document may be accessed from the following location:
