OneDrive is NOT a Backup. Here's Proof

Deleted files, ransomware sync, and departing staff: 3 ways OneDrive fails when you need it most. What real backup looks like.

We hear it weekly: “We have OneDrive, so we are backed up.” Until:

Case 1 - Deleted: Admin deleted a user, OneDrive deleted 3 years of files 30 days later. No recycle bin. Our cloud backup restored in 20 minutes.

Case 2 - Ransomware: Crypto-locker encrypted local files, OneDrive synced encrypted files to cloud. Version history only kept 30 days. Our immutable backup kept 90 days.

Case 3 - Staff leaving: Sales rep left, deleted client folder before exit. No audit log. Our backup has legal hold.

Real 3-2-1 backup: 3 copies, 2 media, 1 off-site immutable. Automated daily Email, OneDrive, SharePoint, Teams. Tested restore every month. That is what we set up in Managed Support.
