This Tool helps you to sync your VM or directory which stored on ZFS between 2 servers.
This tool also has the capability to add jobs to cron so the sync will be automatically done.
+The default syncing interval is set to 15 min, if you want to change this value you can do this in /etc/cron.d/pve-zsync.
+To config cron see man crontab.
