pve-zsync is a very nice tool. You need to know and understand what you are doing (generally speaking, it is a good advise). 

ZFS is a complex file system with major features, but It has a certain learning curve. 
If you have no notion of ZFS, use another backup strategy or learn some basics about ZFS. 

you should first install pve-zsync and issue a command looking similar to this one : 

pve-zsync create -dest 192.168.210.28:tank/proxmox1 -limit 12600 -maxsnap 7 -name kvm1.srv -source 133 -verbose


Where 192.168.210.28 is the IP of your second host / backup host… and tank/proxmox1 is the dataset where you'll backup. 

First run will actually create the backup and sync It. 
It will also create a cron job available in /etc/cron.d/pve-zsync 

You can edit this file in order to tune the various parameters (most probably the frequency). 


Do read the doc.
