# TODO implement sending items to zabbix
# Use zabbix_sender directly? (for some reason not installed on games vm) https://www.zabbix.com/documentation/current/en/manual/concepts/sender

# Or create python script and use python library? https://www.zabbix.com/documentation/current/en/devel/python
# if using python script I can run the rsync backup command using subprocess, and catch the output of that
# then I can check the bytes sent to calculate the size
