Backup Settings

/etc/rsync_backup.conf

# Backups are 'pull' only.  Too bad there isn't a better way to enforce this.
read only       = yes

# Oh for the ability to retain CAP_DAC_READ_SEARCH, and no other.  
uid             = root

# There's not much point in putting the superuser in a chroot jail
use chroot      = no

# This isn't really an effective "lock" per se, since the value is per-module,
# but there really ought never be more than one, and it would at least 
# ensure serialized backups.
max connections = 1

log file = /tmp/rsync-backup.log
transfer logging = yes
