Create VM
Add Network (as needed)
Click Network > Add
I'm using VLAN 438 here, as this is my dedicated VLAN for backup traffic.
You'll need to make sure you adjust any firewall rules as necessary for your Proxmox VE nodes to reach Proxmox Backup Server on tcp/8007.
Stage the VM
Click "Virtual Machine" > Create > Linux
4 CPU is recommended, but my NAS only has 2 vCPU available
4 GB RAM, plus 1 GB per TB of storage
If unable to see the PBS login screen at boot, change the video card to vga
32 GB is sufficient for PBS host disk
Click "Settings" > Enable Space Reclamation
Putting the VM on dedicated VLAN
Set the .iso file for boot, Autostart to "Yes"
Power on and Install PBS
Select VM and click "Connect"
Install (Graphical, or however you prefer)
Looks good
When setting the root password, set something easy initially, then change once you can logon via HTTP / SSH and paste a stronger password in.
DHCP has pulled an IP in the dedicated VLAN
Upon installation, the interface will be set to static IP configuration. If you want to DHCP-enable the interface later, install isc-dhcp-client and edit /etc/network/interfaces to change the static config to dhcp.
Configure PBS
Log into your PBS server either via SSH or HTTP.
