Let’s take a closer look at SQL Server Fatal Error 9001 and some fixes available for the error. At Bobcares, with our Server Management Services, we can handle your SQL Server issues.

What Is An SQL Server Fatal Error 9001?

When the SQL server fails to open the database for long enough for the backup to be successfully taken, SQL backup error 9001 happens. If the AutoClose property on the database is ON, the database will automatically close when there is no activity. As a result, this error may occur if the database closes abruptly during the backup.

Corrupt databases or log files, a large SQL log file that requires a lot of storage space, and hardware problems are a few additional causes of this error. To get more details on the error, we can run the DBCC CHECKDB‘dbname’.

How To Fix SQL Server Fatal Error 9001?

Let’s discuss some of the following methods to fix the error.

• Turn off Auto Close if it’s currently set to on. With no action throughout the backup process, this will stop the database from closing.

  alter database [database_name] set AUTO_CLOSE OFF;

   
• If there is a storage issue, use DBCC CHECKDB.

  dbcc checkdb('database_name')

   
• If the error occurs due to the corruption of the SQL database or log file, then launch Emergency Mode Repair. This will also help in the completion of the backup operation and the repair of the log file. It is not advisable to use this method because it can result in the deletion of some log file sections.

  DBCC CHECKDB (N'database_name', REPAIR_ALLOW_DATA_LOSS) WITH ALL_ERRORMSGS, NO_INFOMSGS;

   
• Set SQL Server Database Offline and Online again.

  alter database [database_name] set offline with rollback immediate;

  and

  alter database [database_name] set online;

   
• For non-production instances, restarting the SQL Server is a good solution. Restarting SQL Configuration Manager through the Start menu, Windows Server’s Services, or Cmd via net start and net stop are all options.
