Configuring an NDMP policy in a multi-network environment
In an environment where NetApp storage systems are connected to multiple networks, the NDMP policy for Replication Director can be configured to use a specific network for the NDMP backup traffic. To do this, use the Backup From Snapshot operation in the storage lifecycle policy.
If the backup is from the primary storage system (that is, a Snapshot operation plus a Backup From Snapshot operation in one SLP), then the host name associated with the network to use should be entered in the Clients tab of the policy.
Note:
The following examples use commands that are specific to NetApp Data ONTAP 7-mode. Commands can change from version to version. For the latest vendor-specific commands, refer to the vendor's documentation.
For cases where the snapshot is replicated, the default primary name of the secondary storage system is used. To use a different network, set the ndmpd.preferred_interface options on the storage system to the interface that is connected to that network.
For example, in a setup where the secondary storage system is connected to a private network on the e0b interface, connect to the storage system and set the ndmpd.preferred_interface to e0b, as follows:
Netapp3140a2> options ndmpd.preferred_interface e0b
ndmpd.preferred_interface e0b
In this way, the NDMP backup of all the snapshots that are replicated to that storage system will use the private network.
In NetBackup, add NDMP host credentials to indicate the IP address or hostname that is associated with e0b.
