I have bought the NAs synology ds410, which is very cool and designe, it’s small but strong,
You could backup your server directly on this NAS using multiple protocols.
First thing you have to dio is to create a share directory on the NAS, using admin interface.
Once a share named Netbackup was created, you can connect to the server that you want to backup.
For exemple if you want to backup /var/named to the synology just type on your server
# rsync -avzr /var/named/ rsync://10.0.0.10/NetBackup/dns2/named/
