Script for auto backup restore on SQL server 2000?

[Shane]

Hello All,

One can use below mentioned script to restore all databases from available backup:

----------------------------------------------
USE Master;
GO
SET NOCOUNT ON

-- 1 - Variable declaration
DECLARE @dbName sysname
DECLARE @backupPath NVARCHAR(500)
DECLARE @cmd NVARCHAR(500)
DECLARE @fileList TABLE (backupFile NVARCHAR(255))
DECLARE @lastFullBackup NVARCHAR(500)
DECLARE @lastDiffBackup NVARCHAR(500)
DECLARE @backupFile NVARCHAR(500)

-- 2 - Initialize variables
SET @dbName = 'Customer'
SET @backupPath = 'D:\SQLBackups\'

-- 3 - get list of files
SET @cmd = 'DIR /b ' + @backupPath

INSERT INTO @fileList(backupFile)
EXEC master.sys.xp_cmdshell @cmd

-- 4 - Find latest full backup
SELECT @lastFullBackup = MAX(backupFile)
FROM @fileList
WHERE backupFile LIKE '%.BAK'
AND backupFile LIKE @dbName + '%'

SET @cmd = 'RESTORE DATABASE ' + @dbName + ' FROM DISK = '''
+ @backupPath + @lastFullBackup + ''' WITH NORECOVERY, REPLACE'
PRINT @cmd

-- 4 - Find latest diff backup
SELECT @lastDiffBackup = MAX(backupFile)
FROM @fileList
WHERE backupFile LIKE '%.DIF'
AND backupFile LIKE @dbName + '%'
AND backupFile > @lastFullBackup

-- check to make sure there is a diff backup
IF @lastDiffBackup IS NOT NULL
BEGIN
SET @cmd = 'RESTORE DATABASE ' + @dbName + ' FROM DISK = '''
+ @backupPath + @lastDiffBackup + ''' WITH NORECOVERY'
PRINT @cmd
SET @lastFullBackup = @lastDiffBackup
END

-- 5 - check for log backups
DECLARE backupFiles CURSOR FOR
SELECT backupFile
FROM @fileList
WHERE backupFile LIKE '%.TRN'
AND backupFile LIKE @dbName + '%'
AND backupFile > @lastFullBackup

OPEN backupFiles

-- Loop through all the files for the database
FETCH NEXT FROM backupFiles INTO @backupFile

WHILE @@FETCH_STATUS = 0
BEGIN
SET @cmd = 'RESTORE LOG ' + @dbName + ' FROM DISK = '''
+ @backupPath + @backupFile + ''' WITH NORECOVERY'
PRINT @cmd
FETCH NEXT FROM backupFiles INTO @backupFile
END

CLOSE backupFiles
DEALLOCATE backupFiles

-- 6 - put database in a useable state
SET @cmd = 'RESTORE DATABASE ' + @dbName + ' WITH RECOVERY'
PRINT @cmd
----------------------------------------------

Re: Script for auto backup restore on SQL server 2000?

Well, We dont see a point why you are doing this, when you see the data is being lost in the Temporary Database and there is sure some mistake in the process. I have also done these things in Windows 2000 and the data stays there in the Temporary Database and you were asking in SQL Server 2005 and that is the topic of this thread and I told you its not the way and you can just use Backup & Restore option in SQL Server 2005 and its straight forward.

If you dont plan to find whats the problem and say you are doing the same mistake for so many years, you are free to go with it

Thanks.
