Crashplan isn't incompatible with NAS. You can either mount a share and run it from your workstation, or run it directly on the NAS itself. The core of the product is Java so it runs on just about any architecture to boot.
Coming from someone who tried to do this setup, it wasn't worth it. CrashPlan's client isn't something you generally would want to run on your NAS, it takes memory proportionate to the amount of data on your disk (and a fair amount of RAM, at that) and unless you're running an GUI on your NAS it's impossible to configure without a huge headache.
You can run it from your workstation, but if you've got a reasonable amount of data on your NAS then the memory issues will bite you again. Something like Backblaze B2 is more expensive, but I'd rather pay $10/mo to backup the 2TB of data on my NAS (growing every day) and use CrashPlan to backup my computers only.

CrashPlan's client is able to attach to a headless instance [1], but the RAM requirement does mean that it's only really usable on NASes with expandable RAM.
I used Crashplan for 3 years on a Synology NAS. It's a disaster. Every time there was a Synology upgrade, the CP headless server would stop working, and you'd need to reinstall, re-set the keys, etc.
After 10 ou 15 times doing this, I got rid of Crashplan entirely, migrated my backups to Amazon Drive, and never looked back.
Given the lack of decent options, seems the best choice will really be to pony up the $180 for 3TB that Amazon will start charging next year...
