In this article, we shall discuss how to Repair a Corrupt SQL Server Database Without Data Loss. Just imagine yourself as a database administrator. After opening your laptop and checking your database, you receive a message no DBA wants to see: “Database is in suspect mode.” Before you know it, users are already complaining, your manager is already calling, and somewhere inside that inaccessible MDF file are months of critical business data that must not be lost. Please see Azure Application Gateway: Practical Configuration Guide, and Azure Arc for SQL Server PAYG: Installation, Connectivity Requirements and Operational Best Practices.

Sometimes corruption does not result in data loss; many things may cause file corruption, things like sudden power outages, hardware failures, or improper system shutdown.

The first thing that may come to your mind as first troubleshooting steps will be to run DBCC CHECKDB with REPAIR_ALLOW_DATA_LOSS, which most online guides usually recommend. But what those guides usually don’t tell you could happen is that the command can permanently delete entire data pages to force the database back online. The file corruption issue may be fixed, but the data is lost.

In this guide, we will be showing you how to use a tool like Stellar Repair for MS SQL to diagnose and repair a corrupt SQL Server database.
