Syncing piggyback files in a distributed setup

At the moment there is no mechanism to sync piggyback files between a central and a remote site.

To achieve this, please follow these steps:

You need to sync ~/tmp/check_mk/piggyback/ and ~/tmp/check_mk/piggyback_sources/ to the remote site
- In ~/tmp/check_mk/piggyback all piggyback files are stored
- In ~/tmp/check_mk/piggyback_sources all piggyback sources are to be found

Without these files the data will always be interpreted as outdated!

There are for sure several ways to create a small sync mechanism. We recommend using rsyc. Here is a small script.

In order to run the script regularly, you need to create cronjob

#!/bin/env bash

# ./piggyback_sync.sh -s $SOURCE -r $REMOTE

while getopts s:r:h option;
do
	case "$option" in
		s) source_site=${OPTARG}

	rsync -avzu  --delete --progress -h "$source_dir_piggyback_sources" "$remote_dir_piggyback_sources"
