Step-by-step guide

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Without these files, the data will always be interpreted as outdated!

Info
If you're using dcd connections, you should be aware that hosts could be created twice. To avoid this, you should use the restriction option inside the dcd connection parameters Please make sure that you modify your firewall configuration. Rsync needs the TCP Port 873

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

# Purpose:
# This script allows you to sync piggyback files between the central and remote site
#
# Usage:
# ./piggyback_sync.sh -s $SOURCE -r $REMOTE -d 
# The -d option will run rsync with --progress -h -vv to show more debug

while getopts s:r:h:d option;
do
	case "$option" in
		s) source_site=${OPTARG}
		;;
		r) remote_site=${OPTARG}
		;;
	    d) debug='true'
		;;
		h) help='true'
		;;
		*) echo 'Unknown parameter!' && exit 1
		;;
	esac
done
