Solutions to Fix SQL Server Error 3156 “Database Cannot Be Restored”

The error might showcase that you have taken the backup from the location: ‘D:\DB\LiveDB.mdf,’ and now you are attempting to restore the database at: ‘F:\ReportDB\ReportDB.mdf’

So, you can use the WITH MOVE command for relocating the database.

Use the Restore Database [ReportDB] command to copy FROM DISK = ‘xyz.bak’ WITH RECOVERY, and then type MOVE ‘LiveDB’ To ‘ F:\ReportDB\ReportDB.mdf.’ Finally, use the MOVE ‘LiveDB_Log’ TO ‘F:\ReportDB\ReportDB.mdf_Log.ldf’, followed by REPLACE, STATS = 10.

Note: In case you are not aware of user interface handling or do not like the method, you have the option for utilizing the T-SQL commands:

USE [master]
RESTORE DATABASE [databasename] FROM DISK = N’C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\Backup\aw.bak’ WITH FILE = 1,
MOVE N’filename’ TO C:\Program Files\Microsoft SQL Server\MSSQL.3\MSSQL\FTData\Name’.mdf’,
MOVE N’Logfile_log’ TO N’C:\sql\logfile_log.ldf’, NOUNLOAD, STATS = 5

In this code, MOVE clause is used for moving the files to a specified location.

After all these methods and efforts, if you are still not able to restore the database, then it is possible that the BAK file becomes corrupted. Hence, the SQL server won’t support SSMS and T-SQL methods to repair the damaged backup files.
