Hello!

I have found this very interesting PVE-zsync thing, I would like to use it, but I have read IP addresses must be used to configure it.

I have two PVE hosts in two different locations. I would like to sync them so that one is redundant of the other for a quick disaster recovery. They are not directly exposed to the Internet.

I access PVE1 through an SSH jump (ProxyJump) on a publicly exposed machine on its same subnet. I access PVE2 the same way. (And I access their GUI through a tunnel using the jump SSH connection.)

Any idea or workaround to make it possible to use PVE-zsync on this scenario?

Thank you!

Why is not PVE-zsync integrated intro the PVE GUI?
Perhaps it is somehow problematic in some way?
Isn't PVE-zsync the best option when you have two PVEs in different locations and you want them to be redundant for a quick disaster recovery?

On site 1 I have PVE1 and PBS1. On site 2 I have PVE2 and PBS2. Only one PVE is actively hosting guests. As a recovery strategy I configured remote sync between the two PBSs , so in case of a problem at a site I could quickly go the other site's PVE and restore the guests from its local (same-site) PBS.

But, since I read about this PVE-zsync, I think that would be a quicker solution, wouldn't it? Is there any drawback?

Still I don't understand how the two PVEs would communicate through PVE-Zsync, in the documentation I have not seen anything about ports. If they communicate through SSH, can I use a custom port?

Regarding the questions on my previous post, I guess I could make a VPN so that both PVEs could diretly talk to each other using IP addresses.
