Stupid question...how do you backup, the backup server?

Hi All,

Just started using PBS and I have to say that after a bit of head-scratching...it appears to work very well. First backups take a while to complete but after that it makes quick work of doing the incremental updates. Moving off onto LTO5 at circa 140MBs...all just seems to work.

However, a question from the paronoid person on my shoulder...how do I backup...the backup server? Can I take a backup to a Proxmox VE, export the configuration, tar...?

It's a bare metal install.

Thanks,

Scott
 
What are you trying to accomplish? You can already set up remote sync in PBS for datastores, these contain all info needed for complete restore of VMs and CTs.
 
I am looking for a way to backup my PBS server, just in case I needed to rebuild it.
 
You can backup /etc folder manually or with rsync, but usually there isn't much to back up.

Configuration is easy and quick to set back up in the event of a complete rebuild. There isn't a built in way to backup config with PBS as far as I know, same goes for PVE.

Just install PVE as Host OS, and PBS as VM. Add PBS Datastore Disk als RawDevice, and exclude the Disk from Backup.

Gives you also the ability to run an additional admin VM oder Docker on backup host for emergency cases.
 
So, backup of the /etc/proxmox-backup/ directory would be sufficient for doing a bare metal restore (using the installmedia first of course)?

[TUTORIAL] Thread 'Desaster Recovery für den PBS bei Worst Case Szenarios'

Meine ersten Tests habe ich versehentlich im internationalen Forum gepostet (PBS Resore XXL), nun will ich hier die Ergebnisse präsentieren für alle, die noch nicht wissen, wie man es sinnvoll umsetzt.
Ziel: Wie bekomme ich mein System wieder vollständig aufgebaut, wenn meine IT-Infrastruktur komplett zerstört wurde (Brand, Hochwasser, wütende Ehefrau, etc.).

Ausgangssituation:

- man nutzt ein lokales TAPE oder PBS-Remote-Sync als Stage-2-Sicherung auf ZFS (optimal)

Was muss man neben den normalen Backups (PVE-Hosts, VMs, CTs) sichern, um seinen Proxmox Backup...

I created a tar of my /etc contents on PBS, but I am having trouble figuring out how to get it copied off of the bare metal PBS machine. I thought about copying it to the /mnt location where my automatic backups are saved, but I am worried about that potentially creating an error or being automatically deleted.

Is there an easy way perhaps I can mount a USB drive to my PBS, and then copy the tar off the machine?
 
Welcome, @traumadoc2b
The easiest (though a manual one) way is to scp it to whatever sshd server you want :).

Edit: or the opposite: being at some workstation, use scp to download it to the workstation.
