About the network interface for deduplication

If the server host has more than one network interface, by default the host operating system determines which network interface to use. However, you can specify which interface NetBackup should use for the deduplication traffic.

To use a specific interface, enter that interface name when you configure the deduplication storage server.

Caution:

You cannot change the network interface after NetBackup configures the deduplication storage server. Therefore, carefully enter the properties.

The NetBackup REQUIRED_INTERFACE setting has no affect on deduplication processes.
