Does your backup follow the 3-2-1 rule?
The 3-2-1 rule is a widely used, product-independent standard: keep at least three copies of your data, on two different kinds of storage, with one copy off-site. Check what you actually have today and see exactly what, if anything, is missing.
What do you currently have?
Your result
Three copies
You are short of three copies. One backup that fails or is deleted could still leave you with nothing to restore.
Two kinds of storage
If every copy is on the same kind of storage as the original, one failure of that storage type can take all of them out together.
One copy off-site
Without an off-site copy, anything that destroys the original location — theft, fire, flood — can take every copy with it.
Tested restore (not part of the 3-2-1 rule itself, but worth doing)
A backup that has never been restored is unproven. Try restoring one file you do not otherwise need, to confirm it actually works.
How this works
Nothing you check here is saved or sent anywhere — the whole result is calculated in your browser and disappears when you leave the page.
Questions about the 3-2-1 rule
Where did the 3-2-1 rule come from?
It predates any single backup product and is widely taught in IT and data-protection practice generally — it is not specific to Backora.
Does Backora count as more than one of my three copies?
No. Backora is naturally a strong candidate for the off-site copy, but the rule is about having independent copies — a single backup destination, however good, is still only one of the three.
Is 3-2-1 enough on its own for ransomware?
It is a strong foundation, but ransomware readiness has a few extra considerations, such as whether a backup can itself be reached and encrypted by an infection — see the ransomware readiness checklist.
