Snapshot operation in an SLP
A Snapshot operation creates a point-in-time, read-only, disk-based copy of data. NetBackup provides several types of snapshots, depending on the device where the snapshot occurs.
Use a Snapshot operation as the first operation in a storage lifecycle policy for a NetBackup Replication Director configuration.
Table: Snapshot operation characteristics
Characteristic | Description |
|---|
Storage unit selection | The following topics describe the types of snapshot storage units that can be used as the storage for a snapshot operation: A Storage unit selection is necessary in the following situations: If the is to be used by a subsequent operation. The storage unit that is specified for the operation must be a snapshot-capable storage unit that represents the primary storage. If the SLP contains only one operation and that is a operation, specify a storage unit. NetBackup uses that storage unit to determine which media server to use to launch the snapshot job.
If neither situation applies to the SLP, the administrator may select or may simply make no selection. NetBackup uses the storage unit that is selected for the Backup From Snapshot operation. |
Child of | A Snapshot operation cannot serve as the child of any other operation. Therefore, do not click on any other operation in the SLP when adding a Snapshot operation. See Creating a storage lifecycle policy. |
Source for | A Snapshot operation can be the source for the following operations: Backup From Snapshot Index From Snapshot Replication operation

Hierarchy notes | If a Snapshot operation appears in an SLP, it must be first in the operations list. |
Job type | A Snapshot operation generates a Snapshot job in the Activity Monitor. |
Window | Snapshot operations do not offer the option to create an SLP window. See Window tab of the Storage Operation dialog box. |
