You know, what I'd really like is a backup solution that was simple, integrated without a crappy interface (looking at you CrashPlan), painless, private (meaning the backup provider didn't have the keys) and if it were hosted outside the US or United Kingdom then even better.
Currently using Arq, but it's not really integrated nor painless.
Willing to put with iCloud Drive being in the US, and I'm happy Apple doesn't appear to 'need', 'read', or 'want' our data like Google, and they seem to be privacy conscious (i.e. iMessage and now DuckDuckGo in Safari), but some local encryption for iCloud Drive would be nice.
I don't think iCloud drive will comply with current legalisation for storing work related confidential legal and medical documents I need to back up.
That said, still excited about iCloud Drive = Bye Bye Dropbox
