Proxmox Backup Server as backup provider

Problem/Justification
Add support for Proxmox Backup Server as an additional backup provider allowing a local backup for users and orgs

Impact
This addition is optional per implementation and would not have a broad impact on all users.

User Story
A user will implement on-prem on-site or off-site backup of critical datasets for rapid restore while avoiding cloud provider download fees and limited bandwidth

Are you asking to install the ’ Install Proxmox Backup Client’ on TrueNAS Scale?
Just trying to figure out exactly what you are asking for and how it should work.

See Client Installation near bottom? Installation — Proxmox Backup 3.2.7-1 documentation

Since apt/dpkg are blocked in TrueNAS Scale one does not simply install packages.

root@nas01[~]# apt
Package management tools are disabled on TrueNAS appliances.

Attempting to update SCALE with apt or methods other than the SCALE web
interface can result in a nonfunctional system.
root@nas01[~]# dpkg

-rwxr-xr-x 1 root root      225 Jul  8 11:10 pkg_mgmt_disabled

I’m hoping for a more integrated implementation outside of the client itself to allow PBS to be set as a native backup credential and sync job.
