1389 This Tool helps you to sync your VM or directory which stored on ZFS between 2 servers.
1390 This tool also has the capability to add jobs to cron so the sync will be automatically done.
1391 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.
1392 To config cron see man crontab.
1394 =head2 PVE ZFS Storage sync Tool
1396 This Tool can get remote pool on other PVE or send Pool to others ZFS machines
1400 add sync job from local VM to remote ZFS Server
1401 pve-zsync create -source=100 -dest=192.168.1.2:zfspool
1403 =head1 IMPORTANT FILES
1405 Cron jobs and config are stored at /etc/cron.d/pve-zsync
1407 The VM config get copied on the destination machine to /var/lib/pve-zsync/
