License Definitions

  • Last updated on

This article describes the licensing definitions for Barracuda Cloud-to-Cloud Backup (CCB).

Note the following situations 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. 

Microsoft 365

Microsoft Exchange Online

  • Each user with an active Microsoft 365 plan for Exchange that you back up.

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

      • Microsoft requires a license for shared mailboxes larger than 50GB. As such, CCB also requires a license for any shared mailboxes over 50GB.

    • Shared mailboxes that hold a Microsoft 365 plan.

    • Archive mailboxes enabled on users with valid plan do not require a CCB license.

Microsoft OneDrive for Business

  • Each user with an active Microsoft/Office 365 plan for OneDrive that you backup.

Microsoft SharePoint Online

  • Each user in the Microsoft/Office 365 tenant that has been granted access to a SharePoint site that you back up.

  • Users external to the organization will be excluded from the backup.

Microsoft Teams

  • Each user in the Microsoft/Office 365 tenant that has been granted access to Microsoft Teams sites that you back up.

  • Users external to the organization will be excluded from the backup.

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 plan for Exchange, that account is processed as a unique licensed mailbox.

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.
