Microsoft 365 Backup: Why OneDrive and SharePoint Are Not a Full Backup

Microsoft 365 Backup: Why OneDrive and SharePoint Are Not a Full Backup

“We use Microsoft 365, so our data is backed up.”

It’s a very common belief, and an understandable one. Microsoft 365 provides highly resilient cloud services and includes useful recovery features such as recycle bins, version history and retention capabilities.

But storing your business files in OneDrive or SharePoint is not, by itself, the same as having a complete backup strategy.

If an important file is accidentally deleted, an employee account is removed, data is overwritten or ransomware affects synchronised files, you need to know exactly how that information can be recovered, how far back you can go and what happens if the recovery options within Microsoft 365 are not enough.

In this guide, we explain the difference between cloud storage, retention and backup, what protection Microsoft 365 already provides and why many businesses choose to add a dedicated Microsoft 365 backup solution.

Is OneDrive a Backup?

OneDrive protects business files in several important ways, but it should not automatically be treated as a complete backup solution.

OneDrive is primarily a cloud storage and synchronisation service. It allows users to store files online, access them from different devices, collaborate and synchronise changes between their computer and Microsoft 365.

That synchronisation is extremely useful, but it is also an important distinction from backup.

If somebody changes, deletes or corrupts a synchronised file, that change may also be reflected in the cloud environment. Microsoft provides recovery features that can help in many situations, but businesses should understand the limits of those features rather than assuming every version of every file will always be recoverable.

Is SharePoint a Backup?

SharePoint provides centralised cloud storage and collaboration for teams and organisations. Like OneDrive, it includes useful resilience, versioning and recovery capabilities.

However, SharePoint itself should not automatically be considered the business's backup.

A backup strategy should answer questions such as:

  • How far back can we recover a deleted or changed file?
  • Can we recover an entire folder or SharePoint site?
  • What happens if data is deliberately deleted?
  • Can we recover information after a ransomware incident?
  • What happens to data belonging to an employee who leaves?
  • Where is our backup data stored?
  • How quickly could we restore important information?

If you don't know the answers, it is worth reviewing how your Microsoft 365 data is currently protected.

What Does Microsoft 365 Already Protect?

It is important not to give the impression that Microsoft 365 provides no protection. It does.

Microsoft is responsible for operating and maintaining the underlying Microsoft 365 cloud services, including the infrastructure and service resilience required to keep those platforms available.

Microsoft 365 also provides features that can help organisations recover from common problems, depending on the service, configuration and licensing in use.

These can include:

  • Recycle bins for deleted content.
  • File version history.
  • Retention policies and retention labels.
  • Deleted-item recovery features.
  • Administrative and compliance controls.

These are valuable protections, and they can solve many everyday recovery problems.

However, service resilience and data recovery features are not necessarily the same thing as the backup strategy your individual business requires.

Understanding the Shared Responsibility Model

With cloud services, responsibility for protecting business information is shared between the service provider and the organisation using the service.

Microsoft is responsible for operating the Microsoft 365 platform and maintaining the infrastructure behind services such as Exchange Online, OneDrive and SharePoint.

Your business still needs to consider how its own information is managed and protected, including:

  • Who has access to business data.
  • How users and permissions are managed.
  • How long information needs to be retained.
  • What happens when employees leave.
  • How accidental or malicious deletion is handled.
  • How data would be recovered following a cyber incident.
  • Whether your recovery arrangements meet the needs of the business.

Moving information to Microsoft 365 therefore does not remove the need for a data protection and recovery plan.

Where Can Businesses Get Caught Out?

Data loss is not always caused by a major technical failure. In many cases, it begins with ordinary day-to-day activity.

Accidental File Deletion

Someone deletes the wrong file or folder and does not realise immediately.

If the mistake is discovered quickly, built-in Microsoft 365 recovery options may be enough. The difficulty comes when the deletion is only noticed much later or when the required data is no longer available through the expected recovery route.

Files Being Overwritten or Changed

Cloud collaboration means several people can work with the same information.

Version history can be extremely useful when something is changed accidentally, but organisations should still understand how long the versions they require are available and whether their configuration meets their recovery needs.

Ransomware and Synchronised Files

OneDrive synchronisation can mean that changes made to files on a device are reflected in cloud storage.

If ransomware encrypts files that are being synchronised, encrypted or damaged versions may also be synchronised.

Microsoft provides recovery and security capabilities that can help in ransomware scenarios, but a business should have a defined recovery process rather than discovering its options during an incident.

A separate backup can provide another recovery point that is isolated from the affected production data.

Employee Accounts Being Deleted

When somebody leaves a business, their Microsoft 365 account should be dealt with as part of a proper offboarding process.

OneDrive is associated with the individual user's account, so businesses need to ensure important company information is retained or transferred appropriately before the account and its associated data reach the end of their retention lifecycle.

This is particularly important where employees have stored business-critical documents in their personal OneDrive rather than an appropriate shared SharePoint location.

Malicious or Intentional Deletion

Not every deletion is accidental.

A compromised account or a disgruntled user with sufficient permissions may deliberately delete or alter information. A good recovery strategy should therefore consider both accidental mistakes and intentional actions.

What Is the Difference Between Retention and Backup?

Retention and backup can both help protect information, but they are designed for different purposes.

Retention determines how information should be kept or disposed of over a defined period and is particularly important for records management, governance and compliance.

Backup is focused on creating recoverable copies of information so that data can be restored when the production copy is lost, damaged, deleted or otherwise unavailable.

A dedicated backup solution may provide capabilities such as:

  • Point-in-time recovery.
  • Longer recovery periods according to the organisation's backup policy.
  • Granular recovery of individual files, folders, mailboxes or sites.
  • Backup copies stored separately from the live Microsoft 365 data.
  • Recovery following accidental deletion or malicious activity.

Retention and backup can therefore complement each other rather than being treated as interchangeable.

Does Microsoft Have Its Own Microsoft 365 Backup?

Yes. Microsoft offers a dedicated service called Microsoft 365 Backup, alongside the recovery, retention and versioning capabilities already available within Microsoft 365.

There are also third-party Microsoft 365 backup platforms available.

The important question for a business is therefore not simply “Does Microsoft 365 have backup?” but:

“Do we have a backup and recovery solution configured that meets our business requirements?”

The answer will depend on what information the organisation needs to protect, how long it needs to be retained, how quickly it needs to be recovered and the Microsoft 365 services being used.

What Should a Microsoft 365 Backup Protect?

A Microsoft 365 backup strategy should be based on where the organisation actually stores its important information.

Depending on the business and backup platform being used, this may include:

  • Exchange Online – business email, calendars and mailbox information.
  • OneDrive – files belonging to individual users.
  • SharePoint – shared company documents, sites and libraries.
  • Microsoft Teams – relevant Teams-related information and the Microsoft 365 services where Teams content is stored.

The organisation should also decide how long backups need to be retained and how easily individual items or larger sets of data can be restored.

What Should You Look for in a Microsoft 365 Backup?

A backup product is only useful if it supports the recovery the business actually needs.

When reviewing a Microsoft 365 backup solution, consider:

  • Which Microsoft 365 services are protected.
  • How frequently backups are taken.
  • How long recovery points are retained.
  • Whether individual files, folders, mailboxes and sites can be restored.
  • Where backup copies are stored.
  • How access to the backup platform itself is secured.
  • How quickly important data could be recovered.
  • Whether restores are tested.

The objective is not simply to say that a backup exists. It is to know that the right information can actually be recovered when the business needs it.

Should You Test Microsoft 365 Backups?

Yes. A backup should not be assumed to work simply because a dashboard says the backup job completed successfully.

Businesses should periodically test that information can actually be restored.

A restore test can help confirm:

  • The expected data is being protected.
  • Recovery points are available.
  • The restore process works as expected.
  • The people responsible know what to do during a real incident.

This turns backup from something the business hopes will work into a recovery process it has actually checked.

How Telanova Helps with Microsoft 365 Backup

At Telanova, we help businesses understand how their Microsoft 365 data is currently protected and whether their existing recovery arrangements meet their needs.

Rather than assuming OneDrive or SharePoint provides everything required, we can help review:

  • Where important business information is stored.
  • Microsoft 365 retention and recovery settings.
  • OneDrive and SharePoint usage.
  • User lifecycle and offboarding processes.
  • Microsoft 365 backup requirements.
  • Restore and recovery procedures.

This forms part of a wider approach to protecting business systems and making sure important information can be recovered when something goes wrong.

Frequently Asked Questions

Does Microsoft 365 automatically back up my data?

Microsoft 365 includes resilience and a range of recovery, versioning and retention capabilities, but simply using Microsoft 365 does not mean your organisation automatically has a complete backup strategy. Businesses should decide what data needs protecting, how long recovery points are required and how information would be restored following data loss.

Is OneDrive enough for backup?

OneDrive is primarily a cloud storage, synchronisation and collaboration service. It includes useful recovery features, but businesses should not assume that storing a file in OneDrive provides every backup and recovery capability they may require.

Do I need to back up SharePoint?

That depends on your organisation's recovery requirements. SharePoint provides built-in resilience, versioning, recycle bins and other recovery capabilities, but organisations should consider whether those features provide the recovery periods, granularity and separation they require for important business data.

Can ransomware affect OneDrive files?

Yes. If ransomware encrypts files on a device and those changes are synchronised with OneDrive, affected versions can also be reflected in cloud storage. Microsoft provides recovery and security capabilities that can help, but businesses should have a defined recovery strategy before an incident occurs.

What happens to OneDrive files when an employee leaves?

OneDrive is linked to the user's Microsoft 365 account. When an employee leaves, the organisation should follow a proper offboarding process to identify, retain or transfer important business information before the account and associated data reach the end of their configured retention period.

Is Microsoft 365 retention the same as backup?

No. Retention and backup have different purposes. Retention is primarily concerned with keeping or disposing of information according to organisational or compliance requirements, while backup provides recoverable copies of information for restoration following data loss or damage.

Does Microsoft offer a Microsoft 365 backup service?

Yes. Microsoft offers Microsoft 365 Backup as a dedicated backup service. Businesses can also use third-party Microsoft 365 backup solutions. The appropriate approach depends on the organisation's data, retention and recovery requirements.

How often should Microsoft 365 backups be tested?

Backups should be tested periodically as part of the organisation's recovery procedures. The appropriate frequency depends on how critical the data is and the organisation's recovery requirements, but the important point is to verify that data can actually be restored rather than relying solely on successful backup notifications.

The Bottom Line

Microsoft 365 is a highly capable productivity and collaboration platform, and OneDrive and SharePoint include valuable protection and recovery features.

But cloud storage is not automatically the same as backup.

A business should know what information it needs to protect, where that information is stored, how far back it may need to recover it and what recovery options would be available following accidental deletion, ransomware, account removal or another data-loss event.

The most important question isn't simply whether your files are “in the cloud”.

It's whether you know you can get them back when you need them.
