System requirements

Applies to:
  • CrashPlan for Small Business (Mac only)


This article provides the minimum system requirements for using the currently-supported versions of the CrashPlan app and the CrashPlan mobile app. These system requirements apply to CrashPlan for Small Business (previously CrashPlan PRO).

Code42 for Enterprise requirements are provided at Code42 platform System Requirements.
CrashPlan for Home requirements are available on our CrashPlan for Home support site.


  • These system requirements are the minimum requirements to install the CrashPlan app. We recommend using more powerful hardware for the best performance.
  • If your backup is unusually large (more than 1 TB or 1 million files), you must configure the CrashPlan app to use more RAM than the minimum requirement.
  • The CrashPlan app requires an Internet connection for almost all activity, including signing in, backing up, restoring, and changing most settings.
