Note: for the above script, the zabbix database is brought out separately. You only need to back up the configuration table, but do not need to back up the historical data. If there is no zabbix database on the mysql, you can comment out a large section, and you need to set a keyless login for remote backup, otherwise the scp process needs to manually enter a password, resulting in waiting for execution; or use expect to capture and automatically add a password (you need to install expect first).
