Snapshot Replication
NetBackup Snapshot Manager Replication can replicate snapshots on a NetApp cluster mode array. Clustered Data ONTAP (cDOT) is used to replicate snapshots between storage virtual machines (SVMs or vServers) and between cDOT clusters.
The current support is for NAS only. The NetBackup Snapshot Manager supports NetApp synchronous as well as asynchronous replication. For synchronous replication, Sync and StrictSync policies are supported. For asynchronous replication, policies like DPDefault, MirrorAllSnapshots, MirrorAndVault, MirrorLatest, Unified7year and XDPDefault are supported.
The supported policies are represented as 'NetApp_SnapMirror' and 'NetApp_SnapVault' replication type within NetBackup. Users can choose these replication types as the replication destination in SLP to replicate the snapshots to the desired replication destination.
Following table depicts the differentiation of various policies under NetApp_SnapMirror and NetApp_SnapVault.
Policy type | Policy name | Replication type |

MirrorAllSnapshots | ||
MirrorLatest | ||
MirrorAndVault | NetApp_SnapVault | |
