Whats the difference between CrashPlan+ and CrashPlan PRO?
Businesses can use CrashPlan+ to back up business data onsite and offsite, but not online to CrashPlan Central. Use backup sets to back up different groups of files to different location. It does not require technical resources to install or manage. Both CrashPlan and CrashPlan+ represent our consumer offering. CrashPlan PRO is our business / enterprise software. With CrashPlan PRO you receive the features of the CrashPlan+ software in the PRO Client, plus you get your own PRO Server that includes advanced user management features, advanced reporting, a developer API and total control over the server environment (including upgrades).
