No, cloud storage platforms do not automatically back up your files the way most firms assume. Most cloud platforms operate under a "shared responsibility model," meaning the platform protects its own infrastructure, but the firm remains responsible for backing up its own data. Many platforms also only offer a 30-to-60-day window to restore a file after it's deleted - after that, it's often gone for good. Here's what every engineering firm using cloud storage needs to understand.
What the Shared Responsibility Model Actually Means
When you store project files on a cloud platform, it's easy to assume "it's in the cloud, so it's safe." In reality, most cloud storage providers split responsibility into two parts:
- The platform's responsibility: Keeping its servers running, its infrastructure secure, and its service available
- Your responsibility: Protecting your own data, including backing it up, controlling who has access, and recovering it if something goes wrong
This distinction matters because it means the cloud platform is not your backup solution, even though it feels like one.
The 30-to-60-Day Restore Window Problem
Most cloud storage platforms allow you to restore a deleted file but only within a limited window, typically 30 to 60 days. After that window closes, the file is often permanently unrecoverable through the platform itself. For an engineering firm, that means a project file deleted by accident (or through a ransomware attack, a sync error, or a departing employee) could be unrecoverable if it isn't caught in time, and without a separate backup, there's no fallback.
A Real Example
A 10-person engineering firm kept all of their project files in a cloud platform but had no separate backup solution in place. Their former IT provider had never mentioned this, and like many firms, they assumed the cloud platform itself was providing that protection. Alexaur implemented a dedicated backup solution specifically to protect their project files giving them real peace of mind that critical firm files won't be lost, regardless of what happens on the cloud platform's side.
What Engineering Firms Should Do Instead
- Don't assume cloud storage equals backup. Confirm directly with your platform what their responsibility model actually covers.
- Implement a separate, automated backup solution for your project files, independent of your primary cloud storage.
- Test your ability to restore files periodically, don't just assume it will work when you need it.
- Extend protection beyond the platform's restore window, so a deleted or corrupted file from months ago is still recoverable.
Why This Matters More for Engineering Firms
Your project files represent months or years of work: designs, models, client deliverables. A missing file isn't a minor inconvenience; it can mean redoing work, missing a deadline, or damaging a client relationship. The cost of a proper backup solution is small compared to the cost of losing critical project data with no way to get it back.
