How does cloudHQ counts number of license?
A user is defined as one personalized email address (for example, firstname.lastname@example.org) whose cloud account is sync’d, backed up, or migrated. Even if this user uses multiple cloud apps (Dropbox, Salesforce, etc.), we still count it as one user. In the case of Egntye, one Egnyte power user is equal to one cloudHQ licence.
So, for example, if you backing up Egnyte Shared which have 18 power users then you need to have 18 cloudHQ Backup and Sync licences.
