About NDMP support for NetApp clustered Data ONTAP (cDOT)
The following table describes the terminology that is used in this topic.
Table: NetApp cDOT terminology
NetBackup recommends that a NetApp cDOT cluster run in SVM-scoped NDMP mode (also called Vserver aware mode).
NetBackup supports optimal backup, restore, and duplication of NetApp cDOT FlexVol volumes using the CAB extension. The NetApp cDOT server (that runs in Vserver aware mode) provides unique location information (affinity) about volumes and tape drives. Using this affinity information, NetBackup performs a local backup instead of a three-way or remote backup if a volume and a tape drive share the same affinity. If multiple volumes that are hosted on different nodes are backed up or restored using the same job, NetBackup may switch drive paths if necessary (and possible) to perform the local backup.
Note:
The NetApp Infinite volumes can be backed up and restored by using the standard policy types.
Note:
There should be at least one intercluster LIF for each node of the cluster that does not host a cluster-management LIF. This is required for three-way and remote backups. If you do not specify an intercluster LIF, all of the three-way and remote backups for volumes that are not hosted on the same node as the cluster-management LIF fail. NetBackup does not access these LIFs directly, so it does not need credentials for them.
