We restored from backup. It was three weeks old.

The backup job had been green for months. Every morning, a tick. Everyone slept fine. Then the day came that they needed it, and the most recent restorable backup was three weeks old.

Here is how that happens, and it is more common than you would think. The full backup ran weekly and worked. The smaller, more frequent backups that should have filled the days in between had been quietly failing, for a reason nobody noticed, because nobody was looking at those, only at the big green tick on the weekly. So when they restored, they could go back to the last good full backup. Three weeks ago. Everything since was gone.

For this business that was three weeks of orders, invoices, and changes, vanished, to be reconstructed by hand from emails and memory. Not a total disaster. Just an expensive, miserable fortnight that should never have happened, caused by trusting a green light that was only telling half the story.

A backup job reporting success is not the same as a backup you can actually restore to the point you need.

We check the whole chain, for free, read-only: not just whether the job ran, but how far back you could actually recover, and whether the restore works at all. The green tick was telling you something. It just was not telling you everything.
