This article describes the licensing definitions for Barracuda Cloud-to-Cloud Backup (CCB).
Note the following situations that require a CCB license. Barracuda Cloud-to-Cloud Backup licenses are licensed on a per-user basis, meaning that only one CCB license is required per user.

Shared mailboxes that do not hold a Microsoft 365 paid plan do not require a CCB license.

Shared mailboxes that hold a paid Microsoft 365 plan.
For EDU customers, students with a paid Microsoft 365 plan do not require a CCB license.
Archive mailboxes enabled on users with valid plan do not require a CCB license.

License Count and Billing
Barracuda Networks uses the Microsoft Entra ID of each account as the unique identifier to ensure that the correct number of licensed users are billed.
Microsoft provides Cloud-to-Cloud Backup with a list of accounts in your tenant. If the account is enabled and Exchange is provisioned with an active Microsoft 365 paid plan for Exchange, that account is processed as a unique licensed mailbox.
Barracuda Networks uses a rolling 30-day billing cycle. If a licensed mailbox is backed up within the last 30 days, the mailbox is added to the total license count. If the 30-day period has passed and the mailbox is no longer being backed up, the mailbox is dropped from the total license count.
Entra ID
Each user in an Entra ID tenant that has been granted access.
License Count and Billing
Barracuda Networks uses the Microsoft Entra ID of each account as the unique identifier to ensure that the correct number of licensed users are billed.
For customers who purchase Entra ID Backup as a standalone product without Cloud-to-Cloud Backup licensing, license is a per-user basis; all users in the tenant must be licensed. Entra ID Backup is included at no additional cost for customers with Cloud-to-Cloud Backup for Microsoft 365 licensing, but accurate license counts are still required to ensure a consistent experience and accurate reporting.
