¿El mejor script para restaurar múltiples bases de datos con SQL Server 2012?

Esta es la solución más válida que te podemos dar, sin embargo mírala pausadamente y analiza si es compatible a tu trabajo.

Solución:

Guión de Collet con algunas adaptaciones me funcionó. Asegúrese de habilitar xp_cmdshell antes.

DECLARE @FilesCmdshell TABLE (
    outputCmd NVARCHAR (255)
)   
DECLARE @FilesCmdshellCursor CURSOR 
DECLARE @FilesCmdshellOutputCmd AS NVARCHAR(255)

INSERT INTO @FilesCmdshell (outputCmd) EXEC master.sys.xp_cmdshell 'dir /B  C:Backup*.bak'    
SET @FilesCmdshellCursor = CURSOR FOR SELECT outputCmd FROM @FilesCmdshell

OPEN @FilesCmdshellCursor
FETCH NEXT FROM @FilesCmdshellCursor INTO @FilesCmdshellOutputCmd
WHILE @@FETCH_STATUS = 0
BEGIN   
    DECLARE @sqlRestore NVARCHAR(MAX) = 'RESTORE DATABASE [' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '] FROM  DISK = N''C:Backup' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '.bak'' WITH  FILE = 1,  MOVE N''' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + ''' TO N''C:Microsoft SQL ServerSQLINSTANCEMSSQLDATA' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '.mdf'',  MOVE N''' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '_log'' TO N''C:Microsoft SQL ServerSQLINSTANCEMSSQLDATA' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '_log.ldf'', NOUNLOAD,  STATS = 10'
    EXEC(@sqlRestore)

    FETCH NEXT FROM @FilesCmdshellCursor INTO @FilesCmdshellOutputCmd
END

Cómo habilitar xp_cmdshell:

-- To allow advanced options to be changed.  
EXEC sp_configure 'show advanced options', 1;  
GO  
-- To update the currently configured value for advanced options.  
RECONFIGURE;  
GO  
-- To enable the feature.  
EXEC sp_configure 'xp_cmdshell', 1;  
GO  
-- To update the currently configured value for this feature.  
RECONFIGURE;  
GO  

Si los nombres de sus archivos coinciden con los nombres de su base de datos, puede hacer algo como esto:

DECLARE @FilesCmdshell TABLE (
    outputCmd NVARCHAR (255)
)   
DECLARE @FilesCmdshellCursor CURSOR 
DECLARE @FilesCmdshellOutputCmd AS NVARCHAR(255)

INSERT INTO @FilesCmdshell (outputCmd) EXEC master.sys.xp_cmdshell 'dir /B  C:folder*.bak'    
SET @FilesCmdshellCursor = CURSOR FOR SELECT outputCmd FROM @FilesCmdshell

OPEN @FilesCmdshellCursor
FETCH NEXT FROM @FilesCmdshellCursor INTO @FilesCmdshellOutputCmd
WHILE @@FETCH_STATUS = 0
BEGIN   
    DECLARE @cmd NVARCHAR(MAX) = 'RESTORE DATABASE [' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '] FROM  DISK = N''C:folder' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '.bak'' WITH  FILE = 1,  NOUNLOAD,  STATS = 10'
    EXEC(@cmd)

    FETCH NEXT FROM @FilesCmdshellCursor INTO @FilesCmdshellOutputCmd
END
