About storage lifecycle policies (SLPs) and Auto Image Replication (A.I.R.)
A storage lifecycle policy (SLP) contains instructions in the form of storage operations that are applied to the data.
The Auto Image Replication (A.I.R.) lets backups be replicated between the NetBackup domains. A.I.R. automatically creates the catalog entries in the target domain as the backups are replicated. Veritas recommends the use of A.I.R. instead of live catalog replication to populate the NetBackup catalog at a disaster recovery site.
Understanding the storage lifecycle policy (SLP) operations (for example, backup, duplication, replication, import, and snapshot) can help determine which logs can be used to troubleshoot an issue. This topic primarily focuses on the Automatic Image Replication (A.I.R.) and duplication process flows. The process flow for other operations, like backups and snapshots, are covered in other topics of this guide.
See the NetBackup Administrator's Guide, Volume I for more information about SLPs and A.I.R.
