Proxmox Backup Server Installation & Configuration Guide

Proxmox Backup Server (PBS) - Amazing OS created by the same amazing Team who gave us Proxmox.
With PBS you can backup your stuff super fast and save on space same time.
In this video i will show you how to setup PBS VM in your Proxmox Cluster. How to configure it and its performance.

Very nice! Thank you for rhe detailed explanation. I'll be doing exactly this on my new 3 node cluster, storing the backups on an NFS store on my TrueNas Scale system. Love your Proxmox series so far, please keep them coming!

[@swubutu]

Thanks again MR.P ... pve node back up very handy , did not knew about this part :D !!

[@safwaniiiiiiz]

Many thanks for the thorough explanation.

Many thanks.

What do you think about the guides that suggest installing PBS in a lightweight LXC container instead? From your experience, are there any benefits to installing on a VM instead?

[@MRPtech]

LXC containers connects directly to HOST which means they can utilize RAM and CPU in better way. For home lab user - that "better" is not huge benefit for me. Main reason why i always go for VM and not LXC (unless i have no other choice but LXC) is Migration in Proxmox Cluster. If i want to migrate VM from Node-1 to Node-2, that migration happens while VM is in "live" state which means that VM will still function during migration. With LXC this migration happens in "restart" state - Proxmox shuts down LXC, migrate and starts UP again. For PBS i could go LXC because PBS only being used during night while backup is going, GC / prune / verify jobs happening. I went with VM as it is habit to run important stuff in VM for me to be able to migrate in "live" state.

If i have two hosts, but on different sites and therefore not in a cluster, can i still "cross backup" from one host to the other and vice versa?

[@MRPtech]

Technically yes. You can link them between using Tailscale. kzbin.info/www/bejne/h3vdm32lr6aMgNEsi=0obhrzaJDnxOolaO Host 1 gets backed up to Host 2 - PBS Host 2 gets backed up to Host 1 - PBS

[@74357175]

@@MRPtech Cool. I already have the two hosts connected via Tailscale, but I do not have them in a cluster. That's not a necessity for simple backup, right?

[@MRPtech]

It is not a necessity - it is more for peace of mind. The way you want to run it is still ok to have. If host-1 dies --- host-2 will have all backups and vice versa. You will have some what fail-safe setup if one of the nodes flips over. With PBS you can setup SYNC job. PBS-1 and PBS-2 will be synced so you will have same backups on both places. What i don't recommend - self-host PBS inside single node. If that single nodes dies, you still can get data back but it is a pain in the back side.

[@74357175]

@@MRPtech Thanks. In this 2-host paradigm, I have PBS1 on HOST1 backing up everything on HOST1, *but* the backups are getting synced to HOST2. This is good. Question: What's the benefit of 1) a SYNC job, as compared with 2) ZFS-send, or even just 3) rsync/rclone?

[@MRPtech]

I don't use PBS sync, but my guess will be ... PBS will be happy if chunks are created / synced in PBS system. You know ... all this file permissions headache. For you with 2 separate PVE boxes - setup PBS and sync between them will be most optimal way to go ... i think. Leave PBS systems to deal with sync and backup instead of introducing another layer on top like ZFS-send or rsync.

No mention of restore or recovery in chapters/transcripts. If you don't show how to recover from a disaster (new server, new storage, etc...) then there's not much point in using this guide.

[@MRPtech]

Bingo . this is why it is Installation and Configuration guide Next one will be restore guide. And to add to this ... restore process is exactly same as with normal Proxmox backup function. Select what you want to restore, press a button and that is it.

[@m23605]

@@MRPtech Sounds good. Would the processes for a disaster recovery and retiring/replacing a node be different?

[@MRPtech]

Difference between replacing dead node or recovering from complete meltdown don't have huge differences. Replacing node just has less steps to do. Replacing node in cluster is easier compared to what you have to do if you have single Proxmox node.
