(I meant to reply to you several hours ago, but HN wasn't letting me post comments for some reason...)
I've got rclone set up to encrypt and upload everything to ACD. There's a section at the bottom of the article that goes into some depth on this and some other backup strategies I've tried in the past (including CrashPlan, Backblaze, and Zoolz, all of which are awful). Check http://jro.io/nas#rclone . I never considered building a second NAS, it does seem pretty stupid, even for an enterprise setup. The whole idea is to get the data off-site.
As a side note, some of the so-called "FreeNAS people" can tend to blindly parrot a given general guideline without really understanding the reasoning behind it or why it might be perfectly valid in certain situations to disregard it. For instance, ask them about bhyve and I promise you'll get at least one response along the lines of "bhyve isn't officially supported in FreeNAS so you shouldn't use it under any circumstances, period."
