Home - Backblaze - cheaper than CrashPlan and I've never had an issue with it.
Mobile - I only care about the photos and videos of my kid - they're automatically uploaded to Dropbox. I sprung for the paid plan and the "oops I screwed up" deleted/revision history.
Work - CloudBerry backup to Dreamhost DreamObjects (cheaper than to Amazon S3) for the few Windows systems. Database is backed up using wal-e to the same location.
