A 100-bed critical access hospital was hit by ransomware that infected 140 workstations. The recovery team still restored every system, with no data loss, as described in the case study.

Microsoft 365 Backup
Your email, files, and Teams data, restorable when Microsoft's built-in features are not enough.
Our Microsoft 365 backup service keeps backups of your tenant data, including email, SharePoint, Teams, and OneDrive, so it can be restored after user error, ransomware, or a compromised account. Microsoft provides retention and service continuity features, but it does not, on its own, provide recovery from those events. It is built for regulated organizations that need to restore data, prove they can, and meet retention requirements.
What Microsoft 365 backup covers
The same tenant data your people use every day.
Mailboxes, including messages, calendars, and contacts, so a deleted or encrypted mailbox can be brought back.
SharePoint and OneDrive
Document libraries and personal files, so overwritten, deleted, or ransomware-encrypted files can be restored to an earlier version.
Teams
Teams data, so a deleted team or channel content is not lost for good.
Tested restores
Restores are tested, so you know a restore works before you need one and can explain it to an auditor or insurer.
How this fits your recovery plan
Tenant backups are one part of a wider backup and disaster recovery program.
Endpoint and server backups
Encrypted backups of workstations and on-premises servers, covered on our backup and disaster recovery page.
Written, tested DR plan
Defined recovery time and recovery point objectives, with tests, so the plan is not just a document.
Retention requirements
Backups support the data retention and backup expectations in rules like the HIPAA Security Rule's contingency plan standard.
Government tenants
For defense contractors moving to GCC High, backup is planned around the migration, not added later.
Who this is for
Microsoft 365 backup is built for regulated organizations that run their business on Microsoft 365.
Case studies
This published case study shows a full system recovery after ransomware. It describes server and workstation recovery, not a Microsoft 365 tenant restore.
