I signed up with CrashPlan about a year ago and really think it is great. The price is very reasonable for offsite backup and it is constantly backing up files if you are on line so I have used it for going back to different versions. It has unlimited storage for the same price.
I do onsite backup on Time Capsule and a second drive in my computer as well as a backup drive on my network using GoodSync which works well. I do this once a day after I have finished and I have Time Capsule setup to backup only once at the end of the day.
