Microsoft 365 provides resiliency and retention features, and Microsoft also offers a separate Microsoft 365 Backup service. However, Microsoft 365 does not automatically provide a dedicated backup for every organization by default, and many businesses still choose third-party backup for independent recovery and simplified restores.

Data stored in Microsoft 365—such as Exchange Online email, OneDrive files, SharePoint sites, and Microsoft Teams content—benefits from Microsoft’s built-in redundancy and high availability. However, redundancy is not the same thing as a dedicated backup designed for straightforward recovery after ransomware, accidental deletion, malicious activity, or long-delayed discovery of missing data.

Microsoft operates under a shared responsibility model. In practical terms, that means your organization is responsible for protecting your data and ensuring it can be recovered when needed. Many businesses assume Microsoft automatically backs up everything in a way they can easily restore, and they only discover the gap after an incident occurs.

Backup vs Redundancy in Microsoft 365

Microsoft’s cloud is engineered for uptime. If a server or component fails, Microsoft can fail over to keep services available. That is redundancy—it helps keep the platform running.

A backup, however, is designed for restoration. Backups typically provide the ability to restore specific data (a mailbox, a folder, a file, a SharePoint library, etc.) from a known point in time, even after events like:

• Ransomware or malicious encryption

• Permanent deletion (intentional or accidental)

• Compromised accounts deleting or altering content

• Retention misconfiguration or unexpected policy behavior

• Discovery of missing data weeks or months later

This is why many organizations implement Microsoft 365 backup from a third-party provider: it adds a separate recovery layer specifically designed for restore scenarios.

What Data Should You Back Up in Microsoft 365?

A comprehensive Microsoft 365 backup plan should cover, at minimum:

• Exchange Online (email, calendars, contacts)

• OneDrive (user files and folders) — often searched as one drive backup

• SharePoint Online (sites, document libraries, lists) — commonly referred to as sharepoint backup

• Microsoft Teams (channel data and files, which commonly reside in SharePoint/OneDrive)

If your organization depends on Microsoft 365 for daily operations, these are not “nice to have” protections—they are core business continuity safeguards.

Common Data-Loss Scenarios: Ransomware, Deletion, and Compromise

Most organizations think of data loss as a hardware failure. In Microsoft 365, the more common causes are operational and security related.

Here are the scenarios we see most often:

• Accidental deletion: A user deletes a folder or mailbox content and does not realize it until much later.

• Delayed discovery: Data disappears, but no one notices for weeks—often beyond typical recycle bin or retention windows (or beyond what was configured).

• Account compromise: A bad actor gains access and deletes emails/files or modifies data to cause disruption.

• Ransomware impacts: While ransomware may begin on a workstation, the damage can spread through synced content—especially if large volumes of files are rapidly modified or encrypted.

This is where third-party backup becomes part of Microsoft 365 ransomware protection. It gives you restore points that help you recover business data cleanly and quickly.

How Third-Party Microsoft 365 Backup Works

Most modern third-party backup solutions are:

• Cloud-to-cloud (no appliance or local infrastructure required)

• Automated (backups run on a schedule without manual effort)

• Designed for granular restore (restore a single message, folder, user, or site)

• Capable of running multiple times per day (commonly 4–6 times daily, depending on vendor and plan)

In short, it is a “set it and forget it” safety net—until the day you need it.

What to Look for in a Microsoft 365 Backup Solution

Not all solutions are equal. When evaluating Microsoft 365 backup, consider these practical features:

1. Coverage

   • Ensure it includes Exchange, OneDrive, SharePoint, and Teams at a minimum.

2. Restore flexibility

   • Can you restore a single file, folder, mailbox item, or entire user quickly?

3. Retention options

   • Can you retain backups for the length of time your business needs (and not just a short default period)?

4. Security and access controls

   • Look for strong admin controls, auditing, and separation of duties to reduce insider risk.

5. Storage and pricing clarity

   • Understand whether storage is capped or unlimited, and what happens as data grows.

Why “Backing Up Somewhere Else” Matters

You may wonder why third-party backup matters if your data is already in Microsoft’s cloud.

A strong backup strategy reduces “single point of failure” risk. In practice, a backup is most resilient when it is isolated from the production environment and stored independently. If everything lives in one place, a worst-case scenario can become a total-loss scenario.

A third-party backup adds a separate layer of protection and recovery options.

Cost Typically Is Not Prohibitive

For most businesses, the cost of third-party Microsoft 365 backup is modest compared to the financial and operational impact of data loss.

As an example, our Microsoft 365 backup service is $5 per user, backs all your data up six times a day and includes unlimited storage, making it a practical way to improve resilience without adding complexity.

Insurance and Governance Considerations

Cyber insurance providers increasingly ask whether corporate data is backed up both on-premises and in the cloud. Implementing third-party backup helps you confidently answer those questions, strengthens your security posture, and supports better outcomes during underwriting and renewals.

It also improves business governance by ensuring recoverability is not dependent on assumptions or undocumented settings.
