Am I correct to assume the plug-in for Free NAS will not support Crash Plan for Small Business? If that is true does anyone know if there are plans for a plug-in to support it?
I used CrashPlan for a few years. Yes they promised to always support their product. But they lied and gave people 60 Days to get their backups elsewhere. They may pull the same stunt with CrashPlan for small business in the future. So I will never use them again. Sounds salty? That's because it is.
I would suggest moving your stuff to AWS
I've done an overwiew on S3 here as well as how to backup using *Nix:

FreeNAS supports S3 natively aswell!
You can always setup a LifeCycle rule to push data in Glacier for much cheaper storage.
If you must use CrashPlan, You can setup Rancher + Docker on FreeNAS 11.1. This guide will get you started:

You can find a CrashPlan Pro docker container here:

Looks like it has support for migration from Home > Pro aswell
