Microsoft 365 keeps your email, files and collaboration tools running in the cloud—but it doesn't guarantee you can get your data back if something goes wrong. That's the uncomfortable truth many businesses discover too late. Microsoft's infrastructure is reliable, yes, but their responsibility ends at keeping the service available. Protecting your data from accidental deletion, ransomware, or a disgruntled employee? That's on you.
What does Microsoft actually protect?
Microsoft runs a world-class infrastructure. They handle hardware failures, power outages at their data centres, and network issues. If their servers go down, they restore service. But here's the catch: they're protecting their systems, not your specific files, emails, or Teams conversations.
The Microsoft Services Agreement is pretty clear about this. It recommends you "regularly backup Your Content and Data." They even capitalise it, which tells you they mean it.
What Microsoft covers:
- Data centre uptime and redundancy
- Hardware and network failures on their end
- Geo-redundant replication (copies of data across regions)
What Microsoft doesn't cover:
- Accidental or malicious deletion by your users
- Ransomware that encrypts your files (synced to OneDrive, it encrypts there too)
- Data retention beyond their standard policies
- Easy recovery of individual items from months ago
Can't I just use the Recycle Bin?
You can—for a while. Deleted emails sit in Recoverable Items for 14 days by default (up to 30 if configured). OneDrive and SharePoint keep deleted files for 93 days. After that? Gone.
Here's where it gets messy. Say your finance manager accidentally deletes an entire folder of contracts in SharePoint. They don't notice for four months. By then, Microsoft's retention window has closed. Without a third-party backup, those files are unrecoverable.
Or consider this: an employee leaves, their account gets deleted, and 30 days later IT realises they needed something from that mailbox. Microsoft's native tools won't help you.
What about ransomware?
This one catches people out. OneDrive has version history, which is genuinely useful. But ransomware is getting smarter. Some variants sit dormant for weeks, encrypting files gradually. By the time you notice, your version history might be full of encrypted copies.
A proper backup solution stores your data separately, with its own retention policies. You can restore from a point before the infection started—not just roll back individual files and hope for the best.
What should a Microsoft 365 backup actually do?
A decent backup solution for Microsoft 365 should:
- Back up everything that matters – Exchange mailboxes, OneDrive, SharePoint sites, Teams (including chat history and channels), and ideally Groups and Planner data.
- Run automatically – Multiple times per day, without someone having to remember.
- Keep data for as long as you need – Years, if your industry requires it.
- Allow granular recovery – Restore a single email, a specific folder, or an entire mailbox. Your choice.
- Store data independently – Separate from your Microsoft 365 tenant, so a compromise there doesn't wipe out your backups.
How does this fit with compliance?
If you're in a regulated industry—healthcare, finance, legal—you likely have data retention requirements. Microsoft's native retention policies can help, but they're designed for compliance holds, not backup and recovery.
There's a difference between "we must keep this data for seven years" and "we need to restore last Tuesday's version of this spreadsheet." Backup solutions handle both scenarios more flexibly than relying on litigation holds and retention labels alone.
Frequently asked questions
Doesn't Microsoft 365's geo-redundancy count as backup?
No. Geo-redundancy protects against Microsoft's infrastructure failing—it copies your data across their data centres. But if you delete a file, that deletion replicates too. It's not a backup; it's high availability.
How often should Microsoft 365 data be backed up?
Most businesses back up at least once daily. Some backup solutions offer multiple snapshots per day, which reduces how much data you'd lose in a worst-case scenario.
Can I back up Microsoft 365 myself without third-party software?
Technically, you could export PST files and download OneDrive contents manually. In practice, this doesn't scale, misses Teams data entirely, and creates a management headache. Purpose-built backup tools exist for good reason.
What happens to backed-up data if we change Microsoft 365 plans?
Your backup data remains intact—it's stored separately from your Microsoft tenant. You can still restore even if you downgrade or switch providers.
