[plug] Setting up NFS for backups.

[Mike Holland]

BTW,
backups over NFS are not generally the best way to go.
Better to get the backup host to shell in and run the archive program 
locally, e.g.
   rsh mailhost tar czf - /somedir > mailhost-backup.tgz

Saves bandwidth, preserves attributes better, less race conditions, no 
hassles with root-squashing et al.
  Of course there are lots of other ways, but avoiding NFS is a good 
start. I've seen too much data corrupted that way.
