Backup and retention
Microsoft replicates your data, but it does not back it up the way most businesses assume. A separate backup for Microsoft 365 is now table stakes for almost every organisation.
In plain English
What is Backup?
Backup is the Microsoft 365 capability that handles backup and retention. It sits inside the wider microsoft 365 support stack, so it shares identity, licensing and admin with the rest of your Microsoft 365 estate rather than living off to one side.
In practice, microsoft replicates your data, but it does not back it up the way most businesses assume. A separate backup for Microsoft 365 is now table stakes for almost every organisation.
Day to day, it covers third-party backup for exchange, sharepoint, onedrive and teams, granular restore for items, sites, mailboxes and chats, long-term retention beyond native limits, and more besides. Most teams use a mix of out-of-the-box configuration and a handful of tailored policies, rather than a bespoke build.
Capabilities
What Backup does
The core capabilities that come with Backup, and the practical difference each one makes to a business running on Microsoft 365.
Third-party backup for Exchange, SharePoint, OneDrive and Teams
Captures and retains data with point-in-time restore, so accidental deletes, ransomware and audit requests stop being a crisis and become a routine recovery.
Granular restore for items, sites, mailboxes and chats
Grounded AI works on your own content with your existing permissions, so people get useful answers and drafts without exposing data they shouldn't see.
Long-term retention beyond native limits
Captures and retains data with point-in-time restore, so accidental deletes, ransomware and audit requests stop being a crisis and become a routine recovery.
Ransomware-resilient, immutable storage
Replication across regions and tested failover keep critical services running through outages, protecting revenue and customer trust on the bad days.

Business benefits
Why teams invest in Backup
The outcomes businesses typically point to when Backup earns its place in the Microsoft 365 estate.
Lower operational cost
Consolidating into Backup usually replaces several point tools and the people-time spent stitching them together, with measurable savings in licensing and admin effort.
Reduced risk
Native controls, audit trails and Microsoft's own security investment raise the floor on protection and make compliance evidence much easier to produce.
Faster productivity
Because Backup is already wired into Microsoft 365, users get the value through tools they already use, instead of learning yet another system.
Scalable foundations
Capacity, regions and features grow with the business, so the platform you choose now still fits when headcount, data volume or geography change.
Better visibility
Centralised reporting across users, devices and workloads gives leadership a clear, current picture of what's happening instead of monthly snapshots.
Future-ready
Microsoft ships new Microsoft 365 capabilities into Backup continuously, so the investment compounds rather than ages out.
Watch out for
Common pitfalls
Backup is powerful out of the box, but a few patterns reliably cause it to under-deliver. Worth checking your current setup against these.
- Assuming Microsoft will restore data from years ago
- No regular restore testing
- Backup admin accounts without MFA or privileged access controls
- Retention policies built around licence cost, not legal need
Is it a fit
How to know Backup is right for you
Backup tends to earn its place when one or more of these signals show up. If several feel familiar, it's usually worth a proper conversation rather than another round of internal debate.
- Recovering from accidental or malicious deletion
- Meeting regulatory retention windows that exceed Microsoft defaults
- Restoring after a ransomware or account compromise event
- Producing historical content for legal or HR matters
