Backup Configuration

/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
# XXX There seems to be an obscure bug with pam_ldap and rsync whereby 
# getpwnam(3) segfaults when (and only when) archiving /etc.  Using a numeric
# uid avoids this bug.  Only verified on Fedora Core 2.
uid             = 0

# There's not much point in putting the superuser in a chroot jail
# use chroot    = yes

# 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
