Veeam Backup for Microsoft Office 365: Availability vs. Recoverability

"Data availability" is a term used to describe product or services continuity at a required service level (SLA) or performance. Data availability on the cloud will be achieved through redundancy zones. On the other hand, "data recoverability" refers to the ability to restore data to the point at which a failure occurred.

In the world of cloud, there is confusion about the meaning of these two terms, and one piece of confusion arises when discussing cloud services. The assumption is that when moving a workload to the cloud, there will be no need for data backup. However, this is a mistake; data must be backed up. It appears this happens due to the lack of understanding of the above two terms.

All the great features that Office 365 Exchange Online offer to you and your business still hold hidden risks, including the lack of comprehensive backup and limited recoverability.

Considering these risks, you should ask yourself:

To ease your concerns, Veeam Backup for Microsoft Office 365 will help you to:

NOTE: This testing is built on the beta version, so some of the screens are listed as TBD or may not have their icons/visualization complete, as what you’ll see in the generally available build.

Veeam Backup for Microsoft Office 365 architecture

Veeam Backup for Microsoft Office 365 is integrated with Veeam Backup & Replication, which means you can back up hybrid cloud environments and migrate mailbox data between Office 365 and your on-premises Exchange deployment.

Office 365 Exchange Online first line of defense

The first line of defense when retrieving a deleted mailbox item is retrieving it from the deleted items store, which works only if the item’s retention period has not expired. By default, the retention policy is set to 30 days. Deleting entire mailboxes also calls up the retention policy, also set to 30 days by default. Of course, these defaults can be changed from the Exchange Admin Center.

How then, is Microsoft protecting my Office 365 email data?

Microsoft uses its Exchange Data Availability Group (DAG) to protect your data. For internal use only they also utilize traditional backup to protect Office 365 from any catastrophic disasters. Unfortunately, local failures still can happen to anyone, and the above methods will not protect you from mailbox corruption, nor will these methods restore your mailbox to a point in time. Your SLAs, or data availability requirements, will be defined by Microsoft SLA policies, but they will not provide data recoverability.
