Disaster recovery basics for small teams
Small teams often skip disaster recovery — it feels like enterprise overkill until the day a database is accidentally wiped or a server fails and there's no plan. The truth is that a little preparation, maintainable by a small team, is the difference between a bad afternoon and an existential crisis. Here are the basics.
Back up — and actually test the backups
Backups are the foundation, but a backup you've never restored is just a hope. The most common and painful failure is discovering, mid-crisis, that the backups were incomplete, corrupted, or never actually ran. So: automate your backups, keep copies somewhere separate from the live system, and — most importantly — regularly practise restoring from them. A tested restore is the only backup you can trust.
Write a simple plan
You don't need a hundred-page document. You need a short, written answer to a few questions:
- What are the likely disasters? Server failure, data deletion, a key service going down.
- How do we recover from each? The concrete steps to restore service.
- Who does what? So there's no confusion when everyone's stressed.
- How do we communicate? To your team and to users, if they're affected.
Writing it down turns panic into a checklist.
Set realistic recovery goals
Two simple questions frame everything: how much data can you afford to lose (which sets how often you back up), and how quickly do you need to be back (which sets how much recovery capability you invest in)? A tighter answer costs more, so be honest about what your business actually needs. For many small teams, "we can lose at most an hour of data and be back within a few hours" is a perfectly good, affordable target.
You will have a bad day eventually. Disaster recovery decides whether it's a hiccup or a headline.
- Automate backups, store them separately, and test restores regularly.
- Write a short plan: likely disasters, recovery steps, roles, communication.
- Set realistic goals for acceptable data loss and recovery time.
- Prepare before the incident — that's the whole point.
Frequently asked questions
What's the difference between a backup and a disaster recovery plan?
A backup is a copy of your data. A disaster recovery plan is the whole process for getting back up and running after something goes wrong — which includes backups, but also how you'd restore them, who does what, and how long it takes. Backups without a tested plan can give false confidence.
How often should we test our backups?
Regularly — and 'test' means actually restoring from them, not just checking they ran. An untested backup is a guess. Many teams only discover their backups are incomplete or broken at the worst possible moment, during a real incident.
Do small teams really need disaster recovery?
Yes. Small teams are often the least prepared and the most hurt by data loss or extended downtime. You don't need an elaborate plan — just tested backups and a simple, written process — but you do need something.
