Backup From Snapshot operation in an SLP
Use the Backup From Snapshot operation to create a tar-formatted copy of the snapshot. The new copy is a backup copy. The process is sometimes referred to as a snapdupe job.
Table: Backup From Snapshot operation characteristics
Characteristic | Description |
|---|---|
Destination storage | The selection must be a backup storage unit or a backup storage unit group. The selection cannot be a snapshot storage unit or a snapshot storage unit group. |
Child of | A Backup From Snapshot operation must use a Snapshot operation as its source. See Creating a storage lifecycle policy for snapshots and snapshot replication. |
Source for | A Backup From Snapshot operation can be the source for a Duplication operation. (See Figure: SLP that contains a Backup From Snapshot operation.) |
Hierarchy notes | An SLP may contain more than one Backup From Snapshot operation. If the first Backup From Snapshot operation fails with an unrecoverable error, NetBackup does not attempt the second one. Note: The SLP may contain only one Backup From Snapshot operation if the SLP is used by an NDMP policy (or a Standard or MS-Windows policy with NDMP Data Mover enabled). |
Job type | A Backup From Snapshot operation generates a Backup job in the Activity Monitor. The Backup job that results from the Backup From Snapshot operation is under the control of the SLP Manager. If an SLP window is configured, the Backup job runs during the configured SLP window. If no SLP window is configured, the Backup job can run at any time; possibly outside of the backup window as configured in the backup policy. Users may experience a slight degradation in performance on the client or the client storage device while NetBackup accesses the snapshot. |
Window | An SLP window can be created for a Backup From Snapshot operation. |
