Configuring storage / root for Crashplan?

Hi all,

I've managed to successfully configure several plugins / jails but I'm having an odd issue specifically with Crashplan.
I'm getting this error.
Unlike my other jails / PBI's, Crashplan I figure needs to see the entire array of data (or at least a good portion of it, depending on what you want backed up)...
