Cloud Sync Is Not a Backup - Here's the Difference

The cloud did exactly what it was supposed to

Google Drive. Microsoft 365. The cloud. The owner checked - same encrypted files, synced perfectly, replicated to every connected device within minutes of the infection. The cloud did exactly what it was supposed to do. And now the business had nothing.

Why this happens more than people realize

Most people think cloud sync is the same as backup. It isn't. Sync replicates everything in real time - whatever happens to your files happens everywhere, instantly, including disasters. Backup creates point-in-time snapshots: separate copies that can't be touched by the same attack that hits your main systems. One mirrors the problem. The other lets you go back in time.

The number that should change how you think about this

According to Veeam's 2025 Ransomware Trends Report, 40% of organizations hit by ransomware on their cloud platforms couldn't fully restore their data. They had cloud storage. They just never had a real backup - the two aren't the same thing, and the gap only becomes visible during an actual incident.

What actually protects you

The 3-2-1 rule still holds: three copies of your data, on two different storage types, with one stored offsite. Immutable backups - copies that can't be altered even with admin credentials - protect against an attacker who's already inside and trying to delete your recovery point along with everything else. And monthly recovery tests are the only real way to know any of it actually works when you need it to.

If you're not 100% sure whether your cloud storage is actually backed up separately from itself, it's worth asking the question now. Because when sync works perfectly in the wrong moment, you're out of options.
