-# backupninja handler to do incremental backups using
-# rsync and hardlinks, based on
-#
-# http://www.mikerubel.org/computers/rsync_snapshots/
-#
-# feedback: rhatto at riseup.net | gpl
-# lot of enhancements grabbed from "rsnap" handler by paulv at bikkel.org
-#
-# Config file options
-# -------------------
-#
-# [general]
-# log = rsync log file
-# partition = partition where the backup lives
-# fscheck = set to 1 if fsck should run on $partition after the backup is made
-# read_only = set to 1 if $partition is mounted read-only
-# mountpoint = backup partition mountpoint or backup main folder
-# backupdir = folder relative do $mountpoint where the backup should be stored
-# days = number of backup increments (min = 5)
-# lockfile = lockfile to be kept during backup execution
-# enable_mv_timestamp_bug = set to "yes" if your system isnt handling timestamps correctly
-# tmp = temp folder
-#
-# [source]
-# from = local or remote
-# testconnect = when "yes", test the connection for a remote source before backup
-# include = include folder on backup
-# exclude = exclude folder on backup
-# ssh = ssh command line (remote only)
-# rsync = rsync program
-# rsync_options = rsync command options
-# exclude_vserver = vserver-name (valid only if vservers = yes on backupninja.conf)
-# numericids = when set to 1, use numeric ids instead of user/group mappings on rsync
-# compress = if set to 1, compress data on rsync (remote source only)
-# bandwidthlimit = set a badnwidth limit in kbps (remote source only)
-# remote_rsync = remove rsync program (remote source only)
-#
-# [services]
-# initscripts = absolute path where scripts are located
-# service = script name to be stoped at the begining of the backup and started at its end
-#
-# You can also specify some system comands if you don't want the default system values:
-#
-# [system]
-# rm = rm command
-# cp = cp command
-# touch = touch command
-# mv = mv command
-# fsck = fsck command
-#
-# You dont need to manually specify vservers using "include = /vservers".
-# They are automatically backuped if vserver is set to "yes" on you backupninja.conf.
