如何在sql server中创建具有唯一名称的每日备份

Question

我想每天使用唯一名称对我的服务器的所有数据库进行完整的数据库备份.为此我有一个想法,保持时间戳,使数据库副本分开.假设服务器上有一个名为ABCD的数据库,那么它应该被备份为:

ABCD_21_03_2013
ABCD_22_03_2013

我怎样才能做到这一点.我对这些类型的SQL备份JOBS了解不多.

Answer 1

要使用诸如Filename_MM_DD_YYYY之类的名称创建每日备份:

1. 在SSMS中,右键单击要备份的数据库
2. 选择任务| 备份
3. 在对话框中,选择备份的类型和位置
4. 在此对话框的顶部,在" 脚本"下拉菜单中选择" 脚本操作到作业"选项
5. 将打开" 新建作业"对话框,第一步创建数据库备份转到第一步,然后单击" 编辑"

现有代码如下:

BACKUP DATABASE [AdventureWorks2012] TO  DISK = N'E:\Test\AdventureWorks.bak' WITH NOFORMAT, NOINIT,  NAME = N'AdventureWorks2012-Full Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10
GO

替换它

DECLARE @SQLStatement VARCHAR(2000) 
SET @SQLStatement = 'E:\Test\AdventureWorks_' + CONVERT(nvarchar(30), GETDATE(), 110) +'.bak' 
BACKUP DATABASE [AdventureWorks2012] TO  DISK = @SQLStatement

6保存作业

数据库备份将命名为:

AdventureWorks_07-29-2013

AdventureWorks_07-30-2013

AdventureWorks_07-31-2013

现在你所要做的就是制定正确的时间表

Answer 2

自动备份服务器上的所有数据库.

关于工作:

查询:

SET NOCOUNT ON;

DECLARE 
      @FileName NVARCHAR(1024)
    , @DBName NVARCHAR(256)
    , @PathName NVARCHAR(256)
    , @Message NVARCHAR(2048)
    , @IsCompressed BIT

SELECT 
      @PathName = 'D:\BACKUP\'
    , @IsCompressed = 1 

DECLARE db CURSOR LOCAL READ_ONLY FAST_FORWARD FOR  
    SELECT
          sd.name
        , file_path = @PathName + FileDate + '_' + name + '.bak'
    FROM sys.databases sd
    CROSS JOIN (
        SELECT FileDate = 'ABCD_' + REPLACE(CONVERT(VARCHAR(10), GETDATE(), 103), '/', '_')
    ) fd
    WHERE sd.state_desc != 'OFFLINE'
        AND sd.name NOT IN ('master', 'model', 'msdb', 'tempdb')
    ORDER BY sd.name 

OPEN db

FETCH NEXT FROM db INTO 
      @DBName
    , @FileName  

WHILE @@FETCH_STATUS = 0 BEGIN 

    DECLARE @SQL NVARCHAR(MAX)

    SELECT @Message = REPLICATE('-', 80) + CHAR(13) + CONVERT(VARCHAR(20), GETDATE(), 120) + N': ' + @DBName
    RAISERROR (@Message, 0, 1) WITH NOWAIT

    SELECT @SQL = 
    'BACKUP DATABASE [' + @DBName + ']
    TO DISK = N''' + @FileName + '''
    WITH FORMAT, ' + CASE WHEN @IsCompressed = 1 THEN N'COMPRESSION, ' ELSE '' END + N'INIT, STATS = 15;' 

    EXEC sys.sp_executesql @SQL

    FETCH NEXT FROM db INTO 
          @DBName
        , @FileName 

END   

CLOSE db   
DEALLOCATE db

输出:

BACKUP DATABASE [AdventureWorks2008R2]
    TO DISK = N'D:\BACKUP\ABCD_24_05_2013_AdventureWorks2008R2.bak'
    WITH FORMAT, COMPRESSION, INIT, STATS = 15;

BACKUP DATABASE [AdventureWorks2008R2_Live]
    TO DISK = N'D:\BACKUP\ABCD_24_05_2013_AdventureWorks2008R2_Live.bak'
    WITH FORMAT, COMPRESSION, INIT, STATS = 15;

BACKUP DATABASE [AdventureWorks2012]
    TO DISK = N'D:\BACKUP\ABCD_24_05_2013_AdventureWorks2012.bak'
    WITH FORMAT, COMPRESSION, INIT, STATS = 15;

结果:

2013-05-24 09:54:34: AdventureWorks2008R2
