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

Term	Definition
CAB	Specifies the Cluster Aware Backup (CAB) NDMP API extension. The CAB enables support of a NetApp cDOT system for optimal, node-transparent backups.
cDOT	Specifies the clustered Data ONTAP (cDOT); the NetApp clustered filer storage solution.
Cluster-management LIF	Specifies a single management interface for the entire cluster. This is the only logical interface (LIF) that NetBackup supports for device configuration.
Data LIF	Specifies the data logical interface (LIF) that is associated with the Vserver.
Intercluster LIF	Specifies a logical interface (LIF) that is used for intercluster communication.
LIF	Specifies a logical interface (LIF); an IP address and port that is hosted on a node of a NetApp cDOT system.
Node-management LIF	Specifies a dedicated IP address that is used to manage a node.
SVM	Specifies the Storage Virtual Machine (SVM); a NetApp clustered Data ONTAP construct that is a virtualization layer that includes volumes and LIFs. This allows for non-disruptive user and NDMP operations when the physical cluster resources change. Multi-tenancy is achieved by multiple SVMs (see the data LIF). The cluster itself is also an SVM (see cluster-management LIF).
Vserver	Specifies the virtual storage server; contains data volumes and one or more LIFs through which it serves data to the clients.

It is recommended to run a NetApp cDOT cluster 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.
