Hey guys,
I was wondering what you're using to backup and restore the whole supervisor?

I do backup the pve config and all vms of course, but sometimes I wish restoring the whole supervisor when things go to shit could be as easy as restoring a vm.

So what do you guys use to backup the whole thing? I need a solution that would work with remote servers in datacenters as well.

Any thoughts? Oh and.... wouldn't mind if it didn't cost a fortune :D
 
Personally, I just minimize how much I customize PVE and back up /etc. I recently replaced my Intel server with a much newer AMD one and this approach had me back up pretty quickly. No worries about requiring different firmware packages or different devices that need a rebuilt initramdisk and that type of thing. But I only have the one machine. Enterprise users have a different set of problems.

A lot of people around here seem to use tools like Ansible to deploy their machines. That method kind of side-steps a whole set of issues, and is likely faster than what I do.

i concur to @BobhWasatch approach. Have a cold standby with similiar hardware specs, potentially with the same shared storage. "Fast Backups, Fast Restores". No harm meant to the "cattle", but this is for me the "Cattle vs. Pets" thingy. Hypervisors should be "Cattle" Apologies to the "Cattle"!)

I used to use Veeam, but it broke with the 6.x kernel upgrade. I have custom scripts with fsarchiver that fill my needs

Try REaR (Relax And Recover) and do a restore test into a VM, IIRC it also backs up the LVM config

If i'm not wrong, it is possible to install Veeam agent in PVE and backup the whole host. Anyone tried it?

You can basically use any backup tool to backup the host, so of course Veeam would work too. I'm wondering however why you would to that? From the issues People reported here Veeams Proxmox support at the moment seems to be a "public beta" at best. Now don't get me wrong: I know enterprise loves Veeam for ther application-aware stuff for AD-DomainControllers and SQL Databases (although they don't support MySQL oder postgres clusters, much "enterprise" indeed) but a host backup is basically like any backup of a Linux server and nothing where this special advantage of Veeam would benefit you much. So I would go with the Opensource backup tool you are most comfortable with. If you use ZFS as filesystem for the host os storage you could also leverage ZFS snapshots and zfs send/receive for it.
