Why the amount of space stored on the server and on your local computers are different

CrashPlan uses a process called deduplication, a data compression technique used to conserve storage space. CrashPlan first shrinks your data by compression and then only backs up block level changes to the original data. In addition a 90 day history of the changes is preserved. This is why your total server storage are often larger than your total files selected.
