Getting Started
CrashPlan is available to UC system personnel at ~$30/Person/Year with 4 desktop/laptop devices per person. No you can't use one license to cover 4 devices for 4 people, it doesn't provide backups of phones, tablets, etc but it is essentially "unlimited" in terms of storage footprint.
To get set up with CrashPlan Backup you will first need to submit a request to have an account set up here
