NDMP backup and recovery overview
In OneFS, you can back up and recover file-system data through the Network Data Management Protocol (NDMP). From a backup server, you can direct backup and recovery processes between an Isilon cluster and backup devices such as tape devices, media servers, and virtual tape libraries (VTLs).
Some of the NDMP features are described below:
- NDMP supports two-way and three-way backup models.
- With certain data management applications, NDMP supports backup restartable extension (BRE). The NDMP BRE allows you to resume a failed backup job from the last checkpoint taken prior to the failure. The failed job is restarted immediately and cannot be scheduled or started manually.
- You do not need to activate a SnapshotIQ license on the cluster to perform NDMP backups. If you have activated a SnapshotIQ license on the cluster, you can generate a snapshot through the SnapshotIQ tool, and then back up the same snapshot. If you back up a SnapshotIQ snapshot, OneFS does not create another snapshot for the backup.
- You can back up WORM domains through NDMP.
