The machine on Debian Stretch is a backup server for 2x PostgreSQL, 2x KVM, 1x Samba, Webhost of individual servers with a total volume of 40TB.

Backup server distributes mount points to each of the servers separately over 1GB / s LAN. Incremental backup based on rsnapshot on the side of each of the servers.

How can I calculate the load on the backup server, what to optimize in the NFS settings?

current settings

/export/path/server-1/backup server-1(rw,no_root_sqash,async) /export/path/server-2/backup server-2(rw,no_root_sqash,async) /export/path/server-3/backup server-3(rw,no_root_sqash,async) ...
  • In the network rested and the whole business. For backup host does not make sense to twist something else. Check better monitoring that you, for example, notice that backups fail. Better to set up an automatic check that you can recover from backup. - Small
