Beste script om meerdere databases te herstellen met SQL Server 2012?

Script van Collet met enkele aanpassingen werkte voor mij.

Schakel eerst xp_cmdshell in door de volgende SQL-opdrachten uit te voeren:

-- 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 

Werk vervolgens het onderstaande script bij om de databases te herstellen vanuit de back-upbestanden. Vervang C:\Backup\ met uw lokale map met uw .BAK-bestanden en vervang C:\Microsoft SQL Server\SQLINSTANCE\MSSQL\DATA\ met uw SQL Server-gegevensmap. Dit script gaat er ook van uit dat de .BAK-bestandsnamen overeenkomen met de databasenamen, anders zal het script waarschijnlijk fouten veroorzaken over logische bestandsnamen die niet overeenkomen.

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 Server\SQLINSTANCE\MSSQL\DATA\' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '.mdf'',  MOVE N''' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '_log'' TO N''C:\Microsoft SQL Server\SQLINSTANCE\MSSQL\DATA\' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '_log.ldf'', NOUNLOAD,  STATS = 10'
