First, Thanks for helping(your replay on my thread).
You said you're backing TO a pve server? What I want to backup from a pve server.
Now, I realized I can just use rsync+cron and deal with this whole backup thing, but it's just not a realistic solution. since it'll just backup the whole data every time. (About rsync, does it effect the system performace? While rsync is backing can the users still use the services without any issues?)
So, in addition to backing up the data with rsync, I realized that Backing up the system database itself is needed, which is my biggest issue right now - In order to to that, I need to know exactly where this database location is, in every server- and I've no idea how to locate it.
Plus, I still can't manage to create an NFS share, or any sort of storage in order to just try to backup something to an external server.
