Question & Answer
Question
How to configure a NIC (Network Interface Card) specifically for use with backup and restore only?
Cause
When using nzbackup/nzrestore with the -dir option and using network mounted storage (NFS) with a dedicated NIC it is common to configure a static route to only use the dedicated NIC for traffic with the storage used with backup and restore.
Answer
Use ifconfig to find the desired interface.
Temporary solution (does not survive a host/linux restart)
With following command create a static network route to the NFS mount using the dedicated NIC:
~]# ip route add <NFS server ip>/32 via <ip of dedicated NIC> dev <ethX or bondX matching dedicated NIC>
To verify the configuration use following command and check the network path is correctly using the chosen dedicated NIC:
tracepath <NFS server ip> to check it routes via <ip of dedicated NIC>
