Proxmox Backup Server on VPS - Security

Hey,

it would make sense to set up a small VPN so that the PBS is only reachable from within. Generally, an IP that is publicly reachable for things that are not supposed to be publicly accessible always carries a risk.
For the VPN I'd recommend something like WireGuard[1], it is lightweight and relatively easy to set up. [2] is a script that set up the server for you and manages users.

Hey guys,

anyone has experience about running Proxmox Backup Server on Public VPS.

Planning to synchronize the local backups to a VPS.

How is it about security?

Thanks in Advance

Eddie
What VPS host are you considering?

I was looking at testing Azure Cloud

Thanks Hannes. I will try it.
 
Works fine, I firewalled it to my servers IP's by fiddling with iptables in the PBS installation.
Also used the option to encrypt the data before sending it to the PBS server.

just remember to backup the decryption keys somewhere else (perhaps your password manager or some such)

Hetzner has very cheap and good storage nodes (SX). They come with DC nvme drives which allow to speed up ZFS(cache,ZIL,Special device). they have a 1G flat and bandwidth is good.
Might be an option for you but it's definitely more expensive than a VPS. Maybe you can share the node with other people, since you can encrypt your backup files with your own key.
