+# 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.
