Making the move to Office 365 provides organizations with many benefits such as increased end-user productivity to reduced cost and complexity of maintaining on-site hardware. While Microsoft and other software as a service (SaaS) vendors provide IT infrastructures and take on the responsibility of ensuring availability and uptime of their applications and services, this often leads to customers having a false sense of security about their data within these services. In fact, Microsoft tells their Office 365 customers that they own their data and are solely responsible for protecting it. Microsoft Exchange, SharePoint, and company file servers located on-premises needed to be backed up; therefore, data residing in Office 365 needs the same level of protection.
Why is Backup Necessary for Office 365?
Microsoft’s primary focus within Office 365 is ensuring that service and data availability are not disrupted. While Microsoft does a great job of reducing the risk of downtime, this doesn’t reduce the risk of data loss. In fact, Microsoft’s options for data recovery are quite limited, but they do provide some basic safety measures:
Use of Recycle Bins and RetentionRecently deleted content from Exchange Online, OneDrive for Business, and SharePoint Online is not deleted immediately. Instead, the deleted content goes through a set of Recycle Bins, each with their own retention policies, before it is deleted permanently. The Recycle Bins act as a safety net for deleted content. While data can be recovered from these Recycle Bins, the retention for each is limited and once the data is out of retention, the data is gone forever.
2. Default retention is 14 days
Document VersioningIf the Document Versioning feature is turned on, OneDrive for Business will retain a number of previous versions for each file that has been modified, and end users are then able to restore back to any of these previous versions. However, this does not provide protection against unintentional or accidental deletion since all versions of a document are deleted when the current version is deleted.
High Availability and Site Collection BackupsMicrosoft uses Database Availability Groups (DAGs) to protect Exchange Online data. While DAGs do a great job of ensuring uptime and preventing against catastrophic disasters, they will not protect against mailbox corruption, nor will they be able to restore individual email-related items or entire mailboxes to a point in time. For SharePoint Online and OneDrive for Business, Microsoft takes backups of site collections every 12 hours and keeps these backups for 14 days. IT administrators have no control over these backups or restores. If a restore is necessary, it can only be initiated by contacting Office 365 support. You also can’t restore a single item, document, asset, or library. A full restore of a site collection is the only option.
Mailbox and Account RetentionWhen employee’s leave an organization, all data in that users’ Exchange Online mailbox and OneDrive for Business account will be permanently deleted 30 days after their account is deleted. To keep this data for future reference or use, it must be backed up or moved elsewhere. Exchange Online mailboxes can be kept for longer periods of time by configuring an In-Place Hold before their account is deleted; however, this is a premium feature not available in some Office 365 plans. Microsoft does all they can to put safeguards in place to prevent their customers from losing data, but Microsoft Office 365 does not specialize in data backup and recovery. Seeking an additional layer of protection against accidental or malicious data loss, organizations have begun to use third-party backup solutions that offer enhanced protection of Office 365 data, longer retention periods, and more robust recovery options.
Complete Protection for Office 365 with Barracuda Cloud-to-Cloud Backup
Barracuda Backup is the leading integrated backup appliance in the world according to IDC’s Purpose-Built Backup Appliance Tracker. Barracuda Backup was built from the ground up around the cloud with features like built-in cloud replication and management. With a strong legacy in onpremises physical and virtual server protection, Barracuda Backup now includes Cloud-to-Cloud Backup for Office 365. Cloud-to-Cloud Backup protects Exchange Online, SharePoint Online, and OneDrive for Business data by backing it up directly to Barracuda Cloud Storage. Cloud-to-Cloud Backup for Office 365 can be used as an add-on to on-premises Barracuda Backup devices or as a standalone subscription.
In backing up Exchange Online, Barracuda Cloud-to-Cloud Backup protects all email messages, attachments, and the complete folder structure of each users’ mailbox.

Barracuda Cloud-to-Cloud Backup for Office 365 eliminates the risk of lost content due to accidental or malicious deletion. You can also retain email messages and files indefinitely if users were to leave your organization—all without having to purchase additional licenses.
Cloud-to-Cloud Backup Features
Automated and On-Demand BackupsMicrosoft Office 365 backups can be fully automated by creating customizable backup schedules to backup data when you want or you can choose to run backups on-demand at any given time. Optionally, backup schedules can be repeated throughout the day as necessary to protect critical data. All Exchange Online, SharePoint Online, and OneDrive for Business data is deduplicated and compressed for maximum storage efficiency and reduced backup windows before being stored in the Barracuda Cloud.
Quick and Easy RestorationAll Office 365 data backed up to the Barracuda Cloud is accessible, searchable, and retrievable from anywhere with an Internet connection. By selecting specific dates from a built-in calendar, pointin-time recovery of data – mailboxes, folders, files, sites, libraries, and email messages – can be achieved. Files or email messages can be restored back to the original user account and location, to a different location within the account, or a completely different user account. Items backed up from SharePoint Online sites can be recovered back to their original location. If you’re looking for a specific file or message but are unsure of its location, the search feature can be used to quickly and easily find the item, as well as where it can be restored or downloaded. 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 (unless multiple files are selected), then they are put into a ZIP file for easier access.
Reporting and StatisticsFor IT Administrators, detailed reporting and audit logging are a key component of a backup solution. Barracuda Cloud-to-Cloud Backup provides backup status and health monitoring 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, folders, and files were added, modified, and removed since the last backup. On the Status page, graphs show the number of items added and amount of data backed up each day. Storage statistics and graphs detail how much data has been backed up overall and the storage efficiency, as well as how much data is actually being stored in the Barracuda Cloud after deduplication and compression. An Audit Log tracks and provides details about every action performed within the Cloud-to-Cloud Backup interface.
UsabilityBarracuda Backup has always been known for ease of use, and the Cloud-to-Cloud Backup features are no exceptions. Existing Barracuda Backup users will feel right at home with this new functionality, and new users will be able to learn it within minutes.
