As if I want to pay a bunch of strangers to know everything on my computer. No, thanks.
You don’t have to pay the CrashPlan guys, and I doubt they are very concerned about what is on any of our computers. They have a business model that depends on data protection.
If you choose to use their storage, it costs a little, but if you don’t want to pay, then they have it set up so that you and a friend can swap invites. Your data is encrypted and stored on their pc, and his is encrypted and stored on yours.
If there is a catastrophic event, then you simply reinstall crashplan (free) and then login, select your files from your friends storage and you are back up in business.
it is sweet!
