Be aware that running backups over NFS can really saturate an ethernet
and noticibly degrade performance. It's also prone to problems should
the backup machine lose its mount during the backup run. I've seen
admins resort to rebooting their backup box because the NFS-mounted
partition went south and the backup process hung. At my previous job
the net-nazies decided they didn't like the backup traffic and
unilaterally, without consulting the users or admins involved,
firewalled NFS traffic. They wouldn't even allow us to route from our A
subnet to our B subnet.
Dump programs don't generally read NFS partitions, since NFS <> UFS or
ext2 or whatever your physical filesystem really is, so yeah, you're
restricted to using tar to do it. You may also have to play games with
your fstab to give the backup machine root write rights on the NFS mount
so that incrementals can function.
