Install PBS on running PVE host

[Kenneth_H]

Hi
I manage a smaller PVE setup of 5 hosts (3 hosts running VMs and 2 to store backups and restore to when needing to extract data).
PBS is really great news as we run backup for 20-22 hours every day and push close to 10TB of data every day.
We are currently looking into PBS on the two backup nodes, but we are wondering if PBS can be installed alongside PVE on the same node or if we would need to remove the backup-nodes from the cluster and reformat to run on PBS.

Hi Kenneth,

I see your point... but I don't think putting PBS on a PVE Node does make too much sense right now.

First, scalability will be impaired. You only run PBS on one node - the others will just feed that node.
This could lead to a bottleneck.

Second... I don't think it is a good idea to store backups on the same physical system as live-data.

If you absolutely need to: Run PBS in a VM (but for safeties sake use a different storage, i.e. using NFS).

Just my 2.5 cents, though.

We do not recommend this kind of setup, but yes, you can install with apt on your existing Proxmox VE host.

> apt install proxmox-backup-server

(you need to configure the pbs repo first).

What could go wrong or stop working if PBS is installed inside the PVE?
When installing PVE stops responding?

Installing any software may cause problems. At least in my experience ;-)
The usual recommendation is of course to have backups!

No.

PVE listens on port 8006 and PBS utilizes port 8007 --> no conflict.
