If your SaaS runs on a single VPS, try this thought experiment.
It’s 2:17am.
Your app is down.
You log in and see:
Disk at 100%.
Nginx failing to start.
Users emailing.
Now ask yourself:
Can I fully restore production in 30 minutes?
Not “probably.”
Not “I think so.”
Actually restore it.
Most founders can’t.
Not because they’re careless —
because they’ve never tested recovery under pressure.
Here’s the simple 30-minute test:
If you’ve never done this once, you don’t have a backup.
You have a hope.
The difference between stable SaaS and stressful SaaS isn’t scaling.
It’s recoverability.
When was the last time you actually tested a full restore?
