This article lists the system requirements and network ports for your CrashPlan for Small Business environment.

Administration console requirements

  • Minimum resolution: 1024x768

The administration console does not support mobile web browsers.

Code42 app requirements

  • These system requirements are the minimum requirements to install the Code42 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 Code42 app to use more RAM than the minimum requirement.
  • The Code42 app requires an Internet connection for almost all activity, including signing in, backing up, restoring, and changing most settings.
