tarsnap

Sadly there is no documentation for this plugin

#!/bin/sh
#
# Munin plugin for Tarsnap
#
# https://github.com/warrenguy/munin-tarsnap
#
# USAGE:
#
#   Add the following to your backup script (after tarsnap has run), or to a
#   cron job:
#
#     /usr/local/bin/tarsnap --print-stats > /path/to/tarsnap-stats.txt
#
#   N.B.: ensure /path/to/munin-stats.txt is readable by munin-node. The
#   default path this script tries is /var/lib/munin/tarsnap-stats.txt
#
# CONFIGURATION:
#
#   [tarsnap]
#   env.STATSFILE /path/to/tarsnap-stats.txt
