About storage lifecycle policy retention
While creating a storage lifecycle policy in NetBackup, you can specify the destinations where copies should be created. For an SLP, an image can be written to the initial destination as part of the following operations:
BackupImport
You can define the Retention type for each SLP destination. You can select many retention types like Fixed (1, 2, 3 weeks), Expire after Copy, Staged capacity managed etc. The following table explains the meaning of Fixed and Expire after Copy retention types:
|
Fixed |
Fixed retention type means that the backup data is retained for a specific length of time before the backups are expired. When the retention period is reached, NetBackup deletes information about the expired backup. |
|
Expire after Copy |
Expire after Copy retention type means that the image expires after the dependent duplication is complete. |
When you are creating a NetBackup policy, the SLP that you created (like SLP1) can be selected as Policy Storage (storage unit). The SLP (SLP1) is executed when the policy runs.
