Why the error 3183 occur in SQL Server?

The most likely cause for this error is that a SQL Server database page is corrupted. This can happen due to various reasons, such as hardware failure, software problems, operating system issues, etc. For example, if the hard drive sectors are damaged, then the pages get damaged. A power outage can also damage the hardware, thus corrupting the SQL Server database pages. If your operating system fails, it can also damage the database pages. Viruses and malware can also affect the database backup.

Solutions to Fix the Error 3183 in SQL Server

You can follow the below solutions to fix the SQL Server error 3183 and restore the database.

But before that, first check if your database backup is corrupt. For this, you can use the RESTORE command in T-SQL with the VERIFYONLY option (see the below example).

 RESTORE VERIFYONLY FROM DISK = 'C:\Path\To\YourBackup.bak';

This command helps check the integrity of backup file.

Solution 1: Use the CONTINUE_AFTER_ERROR Option

You can try to restore the database with the CONTINUE_AFTER_ERROR option. This option will restore the database but some data may be lost. This option tries to ignore the errors and continue to restore the database.

The following example shows how to restore the database using the CONTINUE_AFTER_ERROR option.

 RESTORE DATABASE [stellar]FROM  DISK = N'e:\Backup\stellar.bak'
 WITH  FILE = 2,
 NOUNLOAD,
 STATS = 5,
 CONTINUE_AFTER_ERROR;

Once restored, you can check the database status by running the DBCC CHECKDB command see the below example).

 DBCC CHECKDB('stellar') WITH NO_INFOMSGS;
