Is OneDrive Actually a Backup? What Small Businesses Need to Know

At its core, OneDrive is a cloud storage and synchronisation service. Save a document into OneDrive on your laptop and it can become available on your other devices. Change that document and the change is synchronised. Delete it and that change can also be synchronised.

Microsoft can also protect common folders such as Desktop, Documents and Pictures using OneDrive Folder Backup, helping those files remain available when a user signs into another computer.

For a small business, that is already a massive improvement over keeping the only copy of an important spreadsheet on one laptop. But synchronisation and independent backup are not quite the same thing.

It would be wrong to suggest that OneDrive gives you no protection. It does. OneDrive supports previous file versions, deleted-file recovery and whole-OneDrive restore features.

For Microsoft work or school accounts, deleted items are normally kept in the OneDrive recycle bin for up to 93 days, unless an administrator has changed the setting. Microsoft 365 users can also restore an entire OneDrive to an earlier point following deletion, corruption or malware activity, with the restore feature covering activity from the previous 30 days.

These features are genuinely useful. In many everyday situations, they can save the day. But they are still recovery mechanisms inside the same Microsoft 365 environment. That is where the difference matters.

Imagine somebody arrives at work and their laptop simply refuses to start. The drive has failed.

If their business documents were stored only on that laptop, you may now have a serious problem. If the files were correctly synchronised with OneDrive, the situation is completely different.

Give the user another computer, sign them back into Microsoft 365 and their OneDrive files can become available again. This is one of the areas where OneDrive is excellent, and one of the reasons we strongly prefer businesses not to keep important files only on individual PCs.

Now imagine somebody accidentally deletes an entire customer project folder. Because OneDrive synchronises changes, that deletion can also appear in the cloud.

Luckily, OneDrive has its recycle bin and recovery tools. If the mistake is discovered soon enough, restoring the files may be simple.

But what happens if nobody notices for months? Or somebody permanently deletes the files? Microsoft notes that a file permanently deleted from the OneDrive recycle bin cannot then be recovered through the normal whole-OneDrive restore process.

An independent backup gives you another place to look.

This is where we become much more cautious about relying only on OneDrive.

Imagine an attacker gains control of a Microsoft 365 administrator account. The concern is no longer simply whether one employee accidentally deleted a spreadsheet. The attacker may have access to the same environment where both the live data and its built-in recovery mechanisms exist.

Microsoft has protections and OneDrive has recovery features, but good backup planning assumes that things can go badly wrong. The UK National Cyber Security Centre advises organisations not to rely solely on cloud-service versioning or deleted-file recovery for critical information and recommends keeping an independent copy in another safe place or service.

That independent separation is the important part.

This is another common misunderstanding. A user looks at File Explorer, sees green ticks next to their files and assumes: “The computer is backed up.”

Not necessarily. It means those particular files are synchronised or available locally, depending on their OneDrive status. There may still be information stored somewhere else on the machine. Desktop or Documents may not have been included in OneDrive Folder Backup. A business application may store data somewhere completely different.

And OneDrive does not mean the whole Microsoft 365 environment is backed up. Email normally lives in Exchange Online. Shared company documents may live in SharePoint. Teams relies on several Microsoft 365 services. OneDrive primarily deals with a user’s own files and files they can access.

So the question should never simply be “Do we have OneDrive?” The better question is: “If something important disappears tomorrow, exactly what can we restore?”

In real business environments, the word backup is sometimes used far too loosely. We are less interested in whether somebody can point at an application and say, “yes, we have backup”. We want to know what the business can actually recover.

That last point matters more than people realise. A backup that has never been tested is partly an assumption. The NCSC similarly recommends regularly testing and monitoring backup health and making sure organisations know how to restore their information.

Not necessarily. This is where IT advice needs to remain practical. There is no point selling every three-person business a complicated backup platform simply because one exists.

It depends on what the business would actually lose. If OneDrive contains a handful of documents that could easily be recreated and the business understands the recovery limitations, the built-in Microsoft protections may be acceptable for that risk.

But the conversation changes when OneDrive, SharePoint, Teams and Microsoft 365 contain the information the company needs to operate: customer documents, contracts, financial records, project information, years of business correspondence and shared company files.

At that point, having an independently managed Microsoft 365 backup becomes much easier to justify. Not because OneDrive is bad. Quite the opposite. OneDrive is very good at the job it was designed to do.

The mistake is expecting one service to solve every possible recovery problem.

Our answer would be: OneDrive can form an important part of your backup and recovery strategy, but for business-critical information it should not automatically be considered your only backup.

Its synchronisation, version history, recycle bin and restore capabilities give businesses valuable protection. But an independent backup provides something different: another recovery route when the original Microsoft 365 environment is the thing you cannot rely on.

And that distinction is what matters.

You do not need to buy anything to find out. As part of the Liugo Free IT Health Check, we can review how your Microsoft 365 data, devices and backups are currently configured and explain what protection you already have.

If everything looks sensible, we will tell you. If there is a gap, we will explain what it is and whether it is actually worth fixing.

No unnecessary complexity and no obligation to change anything.
