备份SQL Server中的所有数据库


13

我有一台Microsoft SQL Server 2005数据库服务器。在数据库服务器中,我大约有250个用户数据库。我必须备份所有这些数据库。由于手动进行备份会花费大量时间,因此我正在寻找可以自动对所有250个数据库进行备份的Batch脚本或DB脚本。有人可以帮忙吗?

注意:首先在D:驱动器上创建一个文件夹。(例如D:\User_DataBackup\

步骤1:创建下面给出的过程。

Create PROCEDURE [dbo].[UserDataBaseBackUp]
AS

BEGIN
SET NOCOUNT ON;

DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
SET @path = 'D:\User_DataBackup\' -- as same as your created folder' 
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),104)
DECLARE db_cursor CURSOR FOR
  SELECT name
  FROM MASTER.dbo.sysdatabases
  WHERE name NOT IN ('master','model','msdb','tempdb','ReportServer','ReportServerTempDB')
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
  SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
  BACKUP DATABASE @name TO DISK = @fileName
  FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor
END

步骤2:执行上述步骤。

 EXEC [UserDataBaseBackUp]

您也可以安排此过程。对该程序进行了测试,希望会对您有所帮助。


做个好事,也许可以通过改进路径来改善?

制定维护计划

SQL Server具有此惊人的功能,它将为您创建脚本和作业

  • 第1步:
    右键点击Maintenance PlanManagement

    右键单击管理

  • 步骤2:为
    您的计划命名

    命名计划

  • 步骤3:
    选择数据库备份任务

    数据库备份任务

  • 步骤4:
    配置任务,选择数据库,文件夹位置,备份类型(完整,差异,事务日志)连接等。

    配置备份任务

  • 步骤5:
    配置作业计划

    配置作业计划


我建议为系统数据库和您的用户数据库制定一个单独的计划,以避免出现任何类型的问题

注意:快速版本的SQL Server不提供维护计划功能。

我知道,使用SSMS维护许多数据库可能会有些混乱,但这很简单。

我可以推荐一种更有效的方法,即使用Ola Hallengren的维护脚本。它非常酷,非常有效。您不仅可以备份所有数据库,还可以执行所有类型的维护过程。

例如,您可以使用以下命令来备份所有数据库,对其进行压缩并使用您选择的证书对它们进行加密(它们都是可选的,并且加密和压缩在SQL Server 2005上将不起作用,但我认为它将可以显示Ola脚本的灵活性和强度):

EXECUTE dbo.DatabaseBackup @Databases = 'USER_DATABASES',
@Directory = 'C:\Backup',
@BackupType = 'FULL',
@Compress = 'Y',
@Encrypt = 'Y',
@EncryptionAlgorithm = 'AES_256',
@ServerCertificate = 'MyCertificate'

根据JP的答案,我添加了一个参数来传递目标目录(并且很可能会添加更多选项):

Create PROCEDURE [dbo].[UserDataBaseBackUp] (
  @OutputDir varchar(255)
) AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @name VARCHAR(50) -- database name
    DECLARE @path VARCHAR(256) -- path for backup files
    DECLARE @fileName VARCHAR(256) -- filename for backup
    DECLARE @fileDate VARCHAR(20) -- used for file name
    SET @path = @OutputDir
    SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),104)
    PRINT 'Starting Backups'
    DECLARE db_cursor CURSOR FOR
        SELECT name FROM MASTER.dbo.sysdatabases
            WHERE name NOT IN ('master','model','msdb','tempdb','ReportServer','ReportServerTempDB')
        OPEN db_cursor
            FETCH NEXT FROM db_cursor INTO @name
            WHILE @@FETCH_STATUS = 0 BEGIN
                SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
                    PRINT 'Starting Backup For ' + @name
                    BACKUP DATABASE @name TO DISK = @fileName WITH FORMAT
                FETCH NEXT FROM db_cursor INTO @name
            END
        CLOSE db_cursor
    DEALLOCATE db_cursor
    PRINT 'Backups Finished'
END
GO

因此:

EXEC UserDataBaseBackUp @OutputDir = 'F:\Backups\SQL Databases\'

1

您可以像这样使用SELECT语句或CURSOR:

DECLARE @PathForBackUp VARCHAR(255)
SET @PathForBackUp = 'F:\Backup\User DB\'

SELECT 'BACKUP DATABASE [' + name + '] TO  DISK = N''' + @PathForBackUp + '' + name + '.bak''
WITH NOFORMAT, NOINIT,  NAME = N''' + name + '_FullBackUp'', SKIP, NOREWIND, NOUNLOAD, COMPRESSION,  STATS = 5'
FROM sys.databases
WHERE database_id > 4

要么

DECLARE @DBName VARCHAR(255)  
DECLARE @PathForBackUp VARCHAR(255) 
DECLARE @FileName VARCHAR(255)  
DECLARE @DateFile VARCHAR(255)
DECLARE @SQL NVARCHAR(2048) 
SET @PathForBackUp = 'F:\Backup\User DB\'  
SET @DateFile = REPLACE(REPLACE(CONVERT(VARCHAR(20),GETDATE(),120) ,' ','T'), ':','') 

DECLARE BACKUPING CURSOR FOR   
SELECT name  
FROM master.dbo.sysdatabases WHERE dbid > 4 

OPEN BACKUPING    
FETCH NEXT FROM BACKUPING INTO @DBName    
WHILE @@FETCH_STATUS = 0    

BEGIN    
        SET @FileName = @PathForBackUp + @DBName + '_' + @DateFile + '.BAK'  
    SET @SQL = 'BACKUP DATABASE '+@DBName+ ' TO DISK = '''+@FileName+''' WITH COMPRESSION ' 
    PRINT @SQL 
    EXECUTE sp_executesql @sql   
    FETCH NEXT FROM BACKUPING INTO @DBName  

END    

CLOSE BACKUPING    
DEALLOCATE BACKUPING

您还可以按Buck Woody的“ 使用PowerShell备份所有用户数据库”中所示使用PowerShell

# Performs a Full backup followed by a transaction log backup on all user databases

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO")  | out-null
$s = new-object ('Microsoft.SqlServer.Management.Smo.Server') 'BWOODY1\SQL2K8'
$bkdir = $s.Settings.BackupDirectory
$dbs = $s.Databases
$dbs | foreach-object {
    $db = $_

    if ($db.IsSystemObject -eq $False -and $db.IsMirroringEnabled -eq $False) {
        $dbname = $db.Name
        $dt = get-date -format yyyyMMddHHmmss
        $dbbk = new-object ('Microsoft.SqlServer.Management.Smo.Backup')
        $dbbk.Action = 'Database'
        $dbbk.BackupSetDescription = "Full backup of " + $dbname
        $dbbk.BackupSetName = $dbname + " Backup"
        $dbbk.Database = $dbname
        $dbbk.MediaDescription = "Disk"
        $dbbk.Devices.AddDevice($bkdir + "\" + $dbname + "_db_" + $dt + ".bak", 'File')
        $dbbk.SqlBackup($s)
        if ($db.DatabaseOptions.RecoveryModel -ne 'Simple') {
            $dt = get-date -format yyyyMMddHHmmss
            $dbtrn = new-object ('Microsoft.SqlServer.Management.Smo.Backup')
            $dbtrn.Action = 'Log'
            $dbtrn.BackupSetDescription = "Trans Log backup of " + $dbname
            $dbtrn.BackupSetName = $dbname + " Backup"
            $dbtrn.Database = $dbname
            $dbtrn.MediaDescription = "Disk"
            $dbtrn.Devices.AddDevice($bkdir + "\" + $dbname + "_tlog_" + $dt + ".trn", 'File')
            $dbtrn.SqlBackup($s)
            }
        }     
    }
