About the network interface for MSDP
If the MSDP storage server has more than one network interface, NetBackup uses the default interface for all deduplication traffic. (Deduplication traffic includes backups, restores, duplication, and replication.) The host operating system determines which network interface is the default. However, you can configure the network interface or interfaces that NetBackup uses, as follows:
Configure a specific interface | To use a specific interface, you can enter that interface name when you configure the deduplication storage server. NetBackup uses this interface for all deduplication traffic unless you also configure a separate interface for duplication and replication. See MSDP network interface properties. See Configuring a storage server for a Media Server Deduplication Pool. |
Configure an interface for duplication and replication traffic | You can configure a separate network interface for the duplication and the replication traffic. The backup and restore traffic continues to use the default interface or the specific configured interface. See About a separate network path for MSDP duplication and replication. See Configuring a separate network path for MSDP duplication and replication. |
The NetBackup REQUIRED_INTERFACE setting does not affect deduplication processes.
