Newbie config question

[John Dalbec]

I want to back up 3 Red Hat 7.1 machines onto a single-drive tape changer
attached to one of them.  I would like to do the backup using only 1 tape for
all three machines.  Which of the machines need to have amanda-client
installed?  Which need to have amanda-server?  Do I need to NFS export the two
machines without a tape drive to the one with a tape drive?  Thanks,
John Dalbec
