# The NAS1 destination is a share called  Backups
# which is accessed via "daemon rsync" at nas1::Backups
# rather than a directory in /home/g4slv
# this allows passwordless rsync. Necessary since the ssh
# server @ nas1 is too old to accept identity keys from
# modern ssh clients - so normal rsync-over-ssh would require
# a password.
#
# Using a "module" overcomes this, and allows for automatic
# backups.
