Earlier posts on this thread (which looks like it dates back to 2009) indicate that x86 is also a requirement. Is that still the case? Or will an ARM-based Linux work as long as it meets the three requirements you listed?
For reference, Synology has a mix of ARM and x86 models:http://forum.synology.com/wiki/index.ph ... y_NAS_have
The "+" models generally (though apparently with some exceptions) run x86 (Intel Atom) CPUs.
I'm probably going to pick up at DS412+ to try out -- just hoping someone could chime in and say, "yes I've made this work!" and save me some surprises.
We're using a Synology at our datacenter with Veeam with no problems, but in that case, it's just exposed as an SMB share.
