1303 This Tool helps you to sync your VM or directory which stored on ZFS between 2 servers.
1304 This tool also has the capability to add jobs to cron so the sync will be automatically done.
1305 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.
1306 To config cron see man crontab.
1308 =head2 PVE ZFS Storage sync Tool
1310 This Tool can get remote pool on other PVE or send Pool to others ZFS machines
1314 add sync job from local VM to remote ZFS Server
1315 pve-zsync create -source=100 -dest=192.168.1.2:zfspool
1317 =head1 IMPORTANT FILES
1319 Cron jobs and config are stored at /etc/cron.d/pve-zsync
1321 The VM config get copied on the destination machine to /var/lib/pve-zsync/
