Proxmox backup and documentation

[hattiehuber]

Hi everyone,

I'm currently working on the fun project of cleaning up and organizing my homelab. I'm running Proxmox, and over time I've accumulated quite a bit of custom configuration—bridges, DDNS, certificates, VMs/LXCs, NFS mounts through /etc/fstab, custom scripts that mount NFS shares after my OMV VM starts, and probably a few other things I've forgotten about.

Most of this has been configured manually, so if the Proxmox host were to fail, I'd potentially have to rebuild everything from scratch.

One thing I have already taken care of is backing up my VMs and LXCs to a remote host.

How do you keep the rest of your Proxmox configuration recoverable? Do you keep your configuration and scripts in Git? Do you document everything? Is there a particular backup or infrastructure-as-code approach you recommend?

There are multiple valid strategies and tools, of course. I am using a "historical" mix of Mediawiki and Gitlab.

You may start with storing away the output of pvereport - it is really valuable if you have to restart from scratch.

Tipp: try to keep everything in one place.

Welcome, @hattiehuber
The quickest method (maybe not optimal, but it's better to have simple backup instead of postponing a backup to the moment you work out a perfect method ):

create a tar archive of /etc and /root (and whatever directory you put your custom scripts) and copy that tar archive to other (secure) physical machine
