The corruption you can't see until you need that page

· Adrian Sullivan

Databases rot quietly. A bad disk sector, a firmware bug, a power event at the wrong moment, and a page deep inside your database becomes unreadable. The database does not stop. It does not warn you. It keeps serving every other page perfectly, while the damaged one sits there, waiting for the day something tries to read it.

That day is usually the worst one. A year-end report. A restore. An auditor pulling a record. The query hits the bad page, the error finally surfaces, and now you are discovering corruption and trying to recover from it at the same time, under pressure, possibly from backups that copied the corruption faithfully every night for months.

The check that finds this exists, is built into the platform, and costs nothing to run. It is also, in a great many estates, never run. Not out of negligence. It is a job somebody was meant to schedule, and then there was always something louder, and the database never complained, so it slid down the list and off the bottom.

If a page in your most important database were quietly corrupt right now, when would you find out, and would your backups save you or just hand you a clean copy of the damage? If you cannot answer that with confidence, you are carrying a risk you cannot see and have never measured.

We run a free, read-only health check that looks for exactly this: the silent rot, the unchecked integrity, the backups nobody has proven. You get the answer in plain English before the bad page picks the moment for you.

Not sure who you need?

Tell us what is going on. A senior DBA reads every message and points you at the right next step, even when that is not us. A free read-only check will tell you whether this one is sitting in your estate.
