What is Code42 and how does it help me backup files?


Code42, previously called CrashPlan, is the software powering the ITS Desktop Backup service, is designed to protect your data files, allowing you to restore your content to a repaired or replaced computer in case of theft or a hard drive crash. Desktop backup solutions are used to automatically back-up critical data stored on university-owned computers that isn't stored elsewhere.

Code42's file version retention allows recovery of clean versions of files in case of a virus or ransomware attack. Code42 is not designed to restore your applications and settings.
