I use CrashPlan (as does my family) and I keep an archive encryption key so it's encrypted on my side. I've found this fantastic (for example when my sister's laptop died as we needed to retrieve her dissertation). It's quite cheap and has unlimited storage. I don't back up everything on here, only the important stuff. I also have a Time Machine drive that sits on my desk for quick access / just to have another option (although it is not encrypted so I might wipe it and find a way to use TM with encryption).
