Easy Steps to Restore Proxmox Single Node Server using PBS

[@demorez5]

first i was a bit disappointed that this is not about some supersecret hack how to backup the proxmox host via PBS, but this actually highlighted some hidden problems in my homelab I would have otherwise realized only once my host crashes

Veeam i try as soon as possible ;) Veeam Agent for Linux IT'S FREE !!!

[@MikeDeVincentis]

Awesome. Quick and to the point. Confirms my setup is on par with yours. Now I just need to configure backing up the hosts using the Helper Script. May be a good video on how to do that and how to save it to the Nas and do a restore of the actual host.

[@MRPtech]

Good idea. Will check that out.

[@drivetrainerYT]

Was waiting for this, thank you!

[@marconwps]

A big problem the PBS don't backup the host how i can backup Proxmox PVE-YT i can't... o windows pc , i hope in the future can be possible.

You can backup Proxmox HOST using PBS. I have demonstrated that in this video: kzbin.info/www/bejne/ZoeVhpuGo7GNgbs

Thanks for the vid

[@olaflampson5420]

Thank you for that excellent video! One question: will this backup the config files of the LXC and the fstab file? I have a passthrough of an igpu configured in the config file and a samba share mounted to the LXC via fstab and the config file. I wonder if that would be restored with the method you presented?

[@MRPtech]

Correct me if i am wrong, your samba fstab file is located inside LXC container, or should be located in LXC container, that file will be backed up as it is part of the LXC container. Config file for igpu on the other hand is located inside proxmox HOST os. You need to backup proxmox host OS too to make sure that config file is backed up. You can backup proxmox os using PBS, i've demonstrated that inside : kzbin.info/www/bejne/ZoeVhpuGo7GNgbs off topic: How you managed to get igpu shared with LXC container :)

@@MRPtech Thank you for the quick response! Will check that out :)

Great, thanks!

Why not use an LXC for PBS if running a single node? Similair to any applications I would put on my PVE host.

[@MRPtech]

Inside single node - LXC is a good option. I went with VM due to migration feature. During migration, VMs getting migrated while in "live" state where LXC containers will be shutdown and started up again after migration. During that migration, LXC container is not functioning.

[@bpinsel4041]

Why did you put the pbs into a vm and not like the other others into an lxc? I actually do prefer the lightweigt lxc's ... Thx.

[@MRPtech]

LXC is lightweight but when you have proxmox cluster and you want to migrate LXC to another node, lxc migration happens in restart mode, which means that lxc will be shutdown, migrated and started from 0. VM migrations happening live. VM will continue to function during migration where LXC container will not

[@pepeshopping]

What about the Proxmox server configuration? Like if you configured nut (ups), will the backup contain all those manual changes you made?

[@MRPtech]

To backup proxmox HOST using PBS you need to use script. I've demonstrated that in this video: kzbin.info/www/bejne/ZoeVhpuGo7GNgbs

[@pepeshopping]

@@MRPtech is that a YES, or a NO!?

[@pepeshopping]

If yiu answer NO: PROXMOX is NOT an Enterprise Appliance! Neeeeext!

[@MRPtech]

Backing up Proxmox HOST will backup everything that is inside Proxmox HOST. every .... single .... file ....

[@tonycayer2102]

This process focuses on restoring VMs from Proxmox Backup Server (PBS) rather than a complete Proxmox Node restoration. Currently, I have not found a method to fully restore a Proxmox Node within a cluster from PBS, especially when additional software like Netdata, Cronicle, and LibreNMS agents are installed on the host. Do you have any recommendations or insights on achieving a full node restoration?

[@kristof9497]

Thank you.

[@robbuurman1667]

Great video again Mr. P ! Thanks again for your effort to teach us all, much appreciated

[@gerry2345]

I like this vid. Good insight and interesting.

[@olaflampson5420]

I just used this method to move my LXCs and VMs from my old to my new server and it worked really well!

[@MRPtech]

I am happy that all worked for you !
