Does the CubeBackup license include Shared drives or do they need to be counted separately?

All Shared drives are automatically included in your CubeBackup license. You can add as many Shared drives as you want without increasing the cost of your license.

An Example:

For example, if 100 users and 50 Shared drives are protected by CubeBackup in your G Suite domain, you will only need a 100-user license.
