Backups vs OneDrive: why they are not the same thing

"It is all in OneDrive, so it is backed up." We hear this weekly, and it is one of the most expensive misunderstandings in small business IT. OneDrive, SharePoint and Teams keep your files available and synced. That is not the same as backed up.

What OneDrive actually protects you from

Hardware failure, a lost laptop, a spilt coffee. Because files live in Microsoft's cloud, the death of one device does not take your data with it. It also gives you version history and a recycle bin, which cover small everyday accidents, for a while.

What it does not protect you from

• Ransomware: sync is a two-way street. When malware encrypts files on a PC, the encrypted versions sync to the cloud within minutes.
• Deletion, malicious or accidental: recycle bins empty on a schedule, typically 93 days. Discover the loss in month four and it is gone.
• A compromised or disgruntled account holder deleting content across sites and mailboxes.
• Microsoft's own shared responsibility line: Microsoft keeps the service running; protecting your data in it is explicitly your job.

What a real backup adds

An independent copy, outside the tenant, on a separate schedule, with long retention and, critically, restore testing. If ransomware syncs poison into OneDrive, the backup from last night is untouched. If a mailbox is deleted and the retention window has passed, the backup still has it. If the whole tenant is compromised, your data exists somewhere the attacker's credentials do not reach.

The test that settles it

Ask one question of your current setup: if every file changed to gibberish at 2am, could you get yesterday's versions back, all of them, and how long would it take? If the answer involves guessing, that is the gap. Our managed backup includes scheduled restore tests, because an untested backup is a hope, not a plan. Book a free IT review and we will check yours.
