How do I restore a batch of transaction logs rather than one by one
There is no ways to specify bunch of transaction log backups (oк folder) to restore in SQL Server Management studio.
But you can find all information about SQL Server backup operations in database MSDB (table backupset and related).
Here is script to generate SQL Server commands for restore database from backup and applying all transaction logs backups performed from last full database backup. I think it should help you.
DECLARE @databaseName sysname
DECLARE @backupStartDate datetime
DECLARE @backup_set_id_start INT
DECLARE @backup_set_id_end INT
-- set database to be used
SET @databaseName = '<your_database_name_here>'
SELECT @backup_set_id_start = MAX(backup_set_id)
FROM msdb.dbo.backupset
WHERE database_name = @databaseName AND type = 'D'
SELECT @backup_set_id_end = MIN(backup_set_id)
FROM msdb.dbo.backupset
WHERE database_name = @databaseName AND type = 'D'
AND backup_set_id > @backup_set_id_start
IF @backup_set_id_end IS NULL SET @backup_set_id_end = 999999999
SELECT backup_set_id, 'RESTORE DATABASE ' + @databaseName + ' FROM DISK = '''
+ mf.physical_device_name + ''' WITH NORECOVERY'
FROM msdb.dbo.backupset b,
msdb.dbo.backupmediafamily mf
WHERE b.media_set_id = mf.media_set_id
AND b.database_name = @databaseName
AND b.backup_set_id = @backup_set_id_start
UNION
SELECT backup_set_id, 'RESTORE LOG ' + @databaseName + ' FROM DISK = '''
+ mf.physical_device_name + ''' WITH NORECOVERY'
FROM msdb.dbo.backupset b,
msdb.dbo.backupmediafamily mf
WHERE b.media_set_id = mf.media_set_id
AND b.database_name = @databaseName
AND b.backup_set_id >= @backup_set_id_start AND b.backup_set_id < @backup_set_id_end
AND b.type = 'L'
UNION
SELECT 999999999 AS backup_set_id, 'RESTORE DATABASE ' + @databaseName + ' WITH RECOVERY'
ORDER BY backup_set_id
Here is an example on how you can auto generate SQL Server restore script from backup files in a directory using TSQL:
Auto generate SQL Server restore script from backup files in a directory
Auto generate SQL Server database restore scripts
you just need a list of sql statements like...
RESTORE LOG AdventureWorks FROM DISK = 'C:\AdventureWorks_1.TRN' WITH NORECOVERY
GO
RESTORE LOG AdventureWorks FROM DISK = 'C:\AdventureWorks_2.TRN'
GO
So you can make a VB script which easily generates this SQL for you from a given folder. Here is an example http://blogs.lessthandot.com/index.php/DataMgmt/DBAdmin/MSSQLServerAdmin/restoring-multiple-transaction-log-backu
Once it has created the SQL you just need to check that it looks right and run it.
I didn't want to use the SQL based approach of the accepted answer, because I didn't want to enable extended stored procedures. So I wrote a powershell script to do it.
You point it at a folder, and it generates a script based on the most recent full backup, and all subsequent transaction log backups.
[System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms")
$foldername = New-Object System.Windows.Forms.FolderBrowserDialog
$foldername.rootfolder = "MyComputer"
$foldername.ShowNewFolderButton = $false
$foldername.SelectedPath = "E:\DatabaseBackups"
if($foldername.ShowDialog() -eq "OK") {
$backupPath = Get-Item($foldername.SelectedPath)
$databaseName = $backupPath.Name
Write-Host($backupPath)
Write-Host($databaseName)
$transactionLogFiles = New-Object System.Collections.ArrayList;
$outputFile = "Restore Database - Script.sql"
$backupFile;
foreach ($file in get-childitem ($backupPath) | sort-object LastWriteTime -descending)
{
if ($file.Extension -eq '.trn')
{
[void]$transactionLogFiles.Add($file);
}
elseif ($file.Extension -eq '.bak')
{
$backupFile = $file;
break;
}
}
Set-Content $outputFile ""
Add-Content $outputFile "USE master"
Add-Content $outputFile "ALTER DATABASE $databaseName SET SINGLE_USER WITH ROLLBACK AFTER 5"
Add-Content $outputFile "RESTORE DATABASE $databaseName FROM DISK = '$($backupFile.FullName)' WITH NORECOVERY";
foreach ($file in $transactionLogFiles | sort-object LastWriteTime)
{
Add-Content $outputFile "RESTORE LOG $databaseName FROM DISK = '$($file.FullName)' WITH NORECOVERY";
}
Add-Content $outputFile "RESTORE DATABASE $databaseName WITH RECOVERY";
Add-Content $outputFile "ALTER DATABASE $databaseName SET MULTI_USER";
Add-Content $outputFile "USE $databaseName"
Write-Host("Script generated at $outputFile");
Write-Host "Press any key to continue ..."
$host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
Invoke-Item $outputFile
}
