@majestyx @if @cmhobbs ultimately I found two good candidates that match my requirements - both with servers in Europe (necessary for speed): Memopal (1) - who only mention up to 500GB but tell me they can do more (just write!); and CeeJay's Crashplan (2) - only a business version of CrashPlan, but with the features I need. Now I'm first going to set up other parts of my pllanned architecture, and then I'll do a trial with both of these. (1) http://www.memopal.com/prices/ (2) http://www.ceejay.net/crashplan-pricing/ #phew - that took a lot of digging (and suggestions from !fediverse as well as #linode IRC people).
