Cloud storage like OneDrive, SharePoint or Dropbox keeps your files available and in sync. Cloud backup keeps separate, protected copies you can restore after a deletion, a ransomware attack or a bad sync. Storage is not backup: if a file is deleted, overwritten or encrypted in OneDrive, that change syncs everywhere, and Microsoft's recycle bins only hold deleted files for a limited time.
The dirty secret of IT support is how many businesses find this out the hard way. "It's all in the cloud" feels safe until someone deletes a client folder in March and nobody notices until July, or ransomware encrypts a laptop and OneDrive faithfully syncs the encrypted files.
Key takeaways
Cloud storage is where your team works: OneDrive, SharePoint, Google Drive, Dropbox. Files sync across devices and are easy to share. That's exactly the problem during a disaster: every change syncs, including the bad ones.
Cloud backup takes point-in-time copies of your data and stores them somewhere separate. If today's version is deleted, corrupted or encrypted, you restore yesterday's, last week's or last month's. The backup doesn't change when your live files do.
Microsoft keeps its service running and gives you recycle bins, but those are designed for quick undo, not long-term recovery:
If nobody notices a problem inside those windows, the data is gone. Microsoft sells a separate Microsoft 365 Backup product for exactly this reason. We back up Microsoft 365 for our clients so email, OneDrive, SharePoint and Teams data can be restored long after the recycle bin has emptied.
The same goes for other cloud apps. Intuit doesn't back up your QuickBooks Online data for you either.
Microsoft's own ransomware guidance is blunt: attackers "invest heavily in neutralizing backup applications," and backups they can reach "can be rendered unusable." Protecting the backup matters as much as having one:
At least quarterly, and after any major change. A backup job that says "success" only proves the job ran. A test restore proves you can get a real file back, and tells you how long a full recovery would take. Microsoft recommends regularly practicing your recovery plan, including recovering "from zero" when every system is down.
This is how we've kept a 100% ransomware recovery rate: we've never failed to restore a client from a ransomware attack. It's also what kept the Women's Resource Center working through the 2025 storms.
Backup is part of the "Secured" foundation of our cybersecurity framework, alongside a business-grade firewall, MFA, endpoint protection and email security. See how our backup and disaster recovery works, or take our cybersecurity tier quiz.
No. OneDrive is cloud storage that syncs your files. If a file is deleted, overwritten or encrypted, that change syncs too. Deleted files stay in the recycle bin for 93 days, and then they're gone. A separate backup keeps independent copies you can restore long after that.
SharePoint and OneDrive keep deleted items for 93 days. Exchange Online keeps permanently deleted email for 14 days by default, and an admin can extend that to 30 days. After that, Microsoft can't restore them.
Keep 3 copies of your data (the original plus 2 backups), on 2 different types of storage, with 1 copy offsite or offline. Microsoft recommends it as part of its ransomware protection guidance.
It can if the backups are reachable from your network with the same credentials. That's why backups should be immutable or offline, stored separately, and protected with MFA so an attacker with a stolen admin account can't delete them.
Most businesses back up key systems at least daily, and more often for data that changes constantly. The right answer depends on how much work you can afford to redo, so we set it system by system.
Test restores. Pick real files and systems, restore them on a schedule and time how long it takes. A backup that has never been restored is a guess, not a plan.
We get it. Backups are invisible until the day you need them. We'll look at what you're backing up today, what's missing and how fast you could really recover, with local engineers in Sarasota and same-day on-site help when you need it. Talk to our team.
