What is the difference between backup software and archive software ?
CrashPlan is designed for live backup of files, and not for archiving files. Think of backup as providing the ability to restore information you have lost. “I’ll back up to there in case something happens here.” Think of archiving simply as an extension of the storage options on your computer. “I’ll store some things there, because I am running out of space here.” Or “These things belong together here; and these other things belong together there.” This means that backup software like CrashPlan cannot be used like iDisk to add, update or remove files from any computer.
