Location

For PVE Node: pr64 and CT 101 the location is at /etc/pve/nodes/pr64/lxc/101.conf

This configuration gets copied over on startup of the container to /etc/pve/lxc/101.conf

Other Mount Info

mkdir /mnt/bak
mount /dev/sddX /mnt/bak

(this is only persistent until the next reboot)

You should then be able to browse the files of that storage in /mnt/bak

Configure storage in PVE GUI or use the CLI:

pvesm add dir bak --path /mnt/bak --content backup
