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.
