Help backing up large mounted directories in LXC containers

So, I've recently setup Proxmox backup server and I figured it would automatically backup all the directories within a container, but it seems to only backup the root file system of the containers. For example I have a LXC named 'vault' that owns;

Code:
mp0: flash:subvol-100-disk-1,mp=/docker,size=128G
mp1: tank:subvol-100-disk-0,mp=/data,size=14000G

Nothing within the data or docker directory was pulled into PBS. Are there extra steps I need to accompish this. Also I have other containers using the exact same mount points. For example, my Plex LXC has the same 'tank:subvol-100-disk-0,mp=/data,size=14000G' I don't want this data to backup twice.

What's the best way to have PBS backup these sub-directories or even the 'flash' and 'tank' storage pool separately? Thanks!
 
I may have figured it out, sorry I'm a little dumb.
