Overview Desktop Backup is powered by CrashPlan, an automated backup utility that stores selected files on the cloud. Only files that are stored on your local machine are covered by Desktop Backup. Other network folders, such as your home directory or shared folders, are backed up differently. In the event of data loss, the CrashPlan application can be used to restore lost files. After some initial setup, CrashPlan will work in the background to save versions of files at set intervals.
