Everyone knows they should back up their data. Far fewer businesses know whether their backups would actually work in a crisis, and that gap is exactly where ransomware and hardware failures do their damage. The good news is that a simple, well-tested rule removes most of the risk.
Why backups fail when you need them
The most common backup mistakes are surprisingly basic: the backup lives on the same computer or server as the original data (so a single failure or ransomware infection takes both), the backup quietly stopped running months ago and nobody noticed, or nobody has ever actually tried to restore from it. A backup you have not tested is really just a hope.
The 3-2-1 rule explained
The industry standard is easy to remember:
- 3 copies of your data (the original plus two backups).
- 2 different types of storage (for example a local drive and cloud storage).
- 1 copy kept offsite, away from your premises.
Follow it and no single event, be it a fire, a theft, a failed drive or a ransomware attack, can wipe out every copy at once.
Why offsite matters against ransomware
Modern ransomware deliberately hunts for connected backups and encrypts those too. An offsite, separated copy that the infection cannot reach is what lets you recover without paying a ransom. It is the difference between a bad afternoon and a business-ending event.
Test it, or it does not count
A backup is only proven when you have successfully restored from it. We periodically test restores for the businesses we look after, so there are no nasty surprises on the day it matters. Backups run automatically, are monitored, and are checked, rather than assumed.
Reliable, tested backups are a core part of our managed IT support, alongside the wider cyber security basics every business should have in place. If you are not completely sure your backups would save you, get in touch and we will check.
