Manual Method to Repair Corrupt SQL .bak File with SSMS

The manual method that we have is quite complex as mentioned earlier. However, users with advanced SQL knowledge can try this. But we do not recommend beginners to try this method as they might end up with data loss or other server issues.

Here, we are using the SSMS, SQL Server Management Studio method. So, Simply follow the below steps carefully.

Set the database in Emergency mode so that nobody else can make changes to it during the recovery task. Run the below command to do so. 


Once the database is set into the emergency mode, simpy run the DBCC command. The command is mentioned below:


After this, users need to simply choose the repair mode. There are three modes available for users as:

  • Repair_Allow_Data_Loss
  • Repair_Rebuild
  • Repair_Fast

None of these three commands complete the task exactly as users want. This is because, rebuild command takes 10 times longer than usual. Fast commands do not repair all the data objects. Lastly, the Allow Data Loss command possesses a risk of data loss & deletion of crucial elements.
