The Common Misconception

Microsoft Keeps Your Data Safe. Doesn’t It?

This is one of the most dangerous myths in IT. Microsoft is responsible for the availability and uptime of the Microsoft 365 platform – not for backing up your data. Microsoft’s own documentation makes this clear, stating that users are responsible for protecting and restoring their own data.

Microsoft’s native retention policies are designed for compliance, not recovery. Deleted items are typically retained for just 30–93 days before they’re gone permanently. That’s not a backup – that’s a time-limited recycle bin.

Blowfish Technology protects your Microsoft 365 data properly – with frequent backups, long-term retention and granular restore so you can recover exactly what you need, exactly when you need it.

Microsoft’s Shared Responsibility Model

Microsoft is responsible for:

Platform uptime, physical security, infrastructure availability and native retention policies

You are responsible for:

Protecting your data from accidental deletion, ransomware, ex-employee actions, and long-term retention

That’s where Blowfish Technology comes in.

Compliance & Retention

Meet Compliance Requirements. Keep Data for Longer.

Many industries require long-term retention of business communications and documents – legal, financial, healthcare and public sector businesses often have obligations to retain data for 5–7 years or more.

Cove’s Microsoft 365 backup retains your data for up to 7 years, stored in SOC 1, SOC 2, ISO 27001 and ISO 9001 certified data centres – helping you meet regulatory requirements without complex and expensive archiving systems.

Common Questions

Microsoft 365 Backup FAQs

Why doesn’t Microsoft back up my data?

Microsoft operates a shared responsibility model. They are responsible for the availability of the platform itself, but protecting your data is your responsibility. Microsoft’s own service agreement states that they recommend customers back up their data using a third-party backup solution.

Can I recover an email that was deleted months ago?

Yes – with our Microsoft 365 backup, you can recover individual emails, folders, calendar items and contacts from any backup point within your retention period. Microsoft’s native retention is limited to 30–93 days; our solution retains data for up to 7 years.

What happens to data when a member of staff leaves?

With Microsoft 365 backup in place, you can retain and access the data from a departed user’s mailbox, OneDrive and Teams for as long as your retention policy requires – even after their licence has been removed. This is critical for compliance and business continuity.

Is Teams data backed up too?

Yes – Cove backs up Teams channels, private channels, posts, replies, messages, embedded content, roles, files and settings. Teams data can be backed up up to 6 times per day, giving you granular restore points for all your communications.

How much does Microsoft 365 backup cost?

Microsoft 365 backup is priced per user per month and is available as a standalone service or as part of our broader managed backup offering. Contact us for a tailored quote based on your user count and retention requirements.
