Does Microsoft back up Microsoft 365 data?
No, not in the way most organisations assume. Microsoft's Service Agreement and Shared Responsibility Model are explicit: Microsoft is responsible for the platform, the customer is responsible for the data. Microsoft 365 retention, recycle bins, and litigation hold are recovery features for accidental deletion within defined windows. They are not backup. They will not survive a malicious deletion by a compromised admin account, a long-dwell ransomware campaign that exhausts versions, or a mass user-account purge.
What is the difference between Microsoft 365 retention and a true backup?
Retention extends how long Microsoft keeps a deleted item before purging it. A backup stores an independent copy that is point-in-time recoverable, ideally immutable, and outside the trust boundary of the source tenant. Retention is overwritten by an attacker. Backup is not. The distinction matters because the failure mode of relying on retention is silent until the recovery event happens.
Does Microsoft 365 Business Premium include backup?
No. Microsoft 365 Business Premium includes Microsoft Purview retention features, eDiscovery and litigation hold. None of those are backup. Backup is a separate product category provided by third-party vendors that integrate with Microsoft Graph (examples include Veeam, AvePoint, Keepit, Barracuda Cloud-to-Cloud Backup, Druva).
Why does the Essential Eight require backup?
ASD Essential Eight Strategy 8 (Regular Backups) requires regular and tested backups of important data, software, and configuration settings. Importantly it requires the backups to be tested and to be retained for an appropriate period. ML2 introduces requirements around restore frequency and protection from modification or deletion by privileged accounts.
Is OneDrive Files Restore the same as a backup?
Files Restore is a self-service recovery feature that lets a user roll back their entire OneDrive to a point in the last 30 days. It is useful for ransomware that encrypts files within that window. It is not a backup because it is bound to the OneDrive itself, has a 30-day ceiling, and does not survive a deleted user account. A long-dwell ransomware attack or a malicious deletion of a user account both defeat Files Restore.
Which services does Frontrow recommend protecting?
All four core Microsoft 365 services: Exchange Online (mailboxes), OneDrive for Business, SharePoint Online (sites), and Microsoft Teams (chats, channel messages, channel files, Loop). The pattern Frontrow runs across Australian mid-market clients is Microsoft Purview retention as the first layer plus a third-party Microsoft 365 backup as the second layer, with quarterly tested restores documented in the operations runbook.
How is this self-assessment validated?
Every scoring threshold cites a primary source: Microsoft Learn for retention and recovery features, the Microsoft Service Agreement and Shared Responsibility Model for the responsibility split, and ASD Essential Eight Strategy 8 for the Australian baseline. The methodology is authored by Daniel Brown (5x Microsoft MVP), Graeme Lodge (Managing Director), and Sam Williams (Investor & Executive Consultant).
What does Frontrow's verified in-tenant backup review include?
A direct review of the customer's tenant configuration via Microsoft Graph and admin console (rather than self-reported answers), test restore drills across mailbox, OneDrive, SharePoint and Teams, gap report against ASD Strategy 8, and a remediation plan with effort estimates. Indicative pricing on request.
