Barracuda Cloud-to-Cloud Backup for Microsoft 365 protects Exchange Online, OneDrive for Business, SharePoint, and Teams data by backing up directly to Barracuda Cloud Storage. For more details about what data is backed up within Cloud-to-Cloud Backup, see Understanding What Data is Backed Up in Microsoft 365.

For a list of features, improvements, and frequently asked questions (FAQs), see Release Notes and Frequently Asked Questions (FAQ).

Scheduled Backups

Barracuda Cloud-to-Cloud Backup automatically sets a schedule to back up your data or you can run backups on-demand at any time. All Exchange Online and OneDrive for Business data is deduplicated and compressed for maximum storage efficiency before being stored in the Barracuda Cloud.

Restore Data

All Microsoft 365 data backed up to the Barracuda Cloud is accessible, searchable, and retrievable from anywhere with an Internet connection. Select specific dates from a built-in calendar, for point-in-time data recovery. Restore files or email messages back to the original user account and location, to a different location within the account, or to a completely different user account. If you are looking for a specific file or message but are unsure of its location, use the search feature to quickly and easily find the item, and then restore or download the item. Downloading folders puts them into a compressed ZIP file for quick downloads, while email messages are downloaded using the industry-standard EML format. Files are downloaded using their same file format. If you select to download multiple files, the files are downloaded as a ZIP file.

Reports and Statistics

Barracuda Cloud-to-Cloud Backup provides backup status for each backup source. Automated email alerts are delivered after each backup to specified email recipients containing a summary of the backup and detailed information about which email messages and files were added, modified, and removed since the last backup. The Dashboard page includes tables showing the number of items added and amount of data backed up each day, including details for how much data has been backed up per backup source and the restore and export status of each backup source. An Audit Log tracks and provides details about every action performed within the Cloud-to-Cloud interface.


With Barracuda Cloud-to-Cloud Backup, all Microsoft 365 data is encrypted in-transit with 128-bit SSL encryption, the same level of security used by most banks and financial institutions. Data stored in the Barracuda Cloud is encrypted at-rest using 256-bit AES encryption. Barracuda Cloud Storage regularly undergoes third-party audits and is SSAE 16 Type II certified. Additional layers of protection included in Barracuda Cloud Control are multi-factor authentication and role-based administration.
