About configuring storage lifecycle policies for snapshots and snapshot replication
A storage lifecycle policy (SLP) contains instructions in the form of storage operations, to be applied to the data. Operations are added to the SLP that determine how the data is stored and copied or replicated. For example, the NetBackup administrator creates an operation that determines where the data exists as a snapshot, as a replication, or as a duplication. The administrator also determines the retention of the data at each storage unit or storage unit group.
Storage operations that are defined in the SLP use storage units that represent disk pools. An SLP that is configured for snapshots or snapshot replication must contain a specific, hierarchical combination of operations.
The following figure represents an SLP for a replication scenario. In the example, the following operations are used:
Table: Example of a storage lifecycle policy configured for snapshots and snapshot replication describes the four types of operations that are required in this example replication scenario.

After the SLP is configured for different operations, the NetBackup administrator configures a backup policy that points to the snapshot SLP.
The SLP Parameters host properties in the NetBackup Administration Console allow administrators to customize how SLPs are maintained and how SLP jobs run.
