Creating a hierarchy of storage operations in a storage lifecycle policy
The list of operations in the storage lifecycle policy acts as a list of instructions to NetBackup about the data that the SLP protects. In some cases, one operation depends on another operation. For example, a snapshot may serve as the source for a replication. Or, a backup may serve as the source of a duplication.
The operation hierarchy in the Storage Lifecycle Policy dialog box represents a parent and child relationship.
Figure: Hierarchical storage operations in an SLP is an example of how the operation list uses indentation to indicate the relationship between a parent operation and a child operation.
One copy can be the source for many other copies. Figure: Hierarchical operations shows how after the first copy is created, all subsequent copies can be made locally from that source, without tying up network resources.
Changing the location of an operation in the hierarchy changes the storage unit that serves as the source for the subsequent copies. Changing the hierarchy cannot change the operation type. (For example, change a backup operation into a duplication operation.)
