作业备份，不是备份数据库，是备份作业。
我的方法是把作业导出成文件备份起来，因为当你服务器维护的多了的时候很多你的作业 就很成问题，很麻烦。
最好能够作业实现同步，这个也是第一步，保存成文件，之后个人设想使用powershell 来把作业同步起来
复制代码代码如下:
DECLARE @jobname VARCHAR(30),@category_calss_i INT ,@category_calss VARCHAR(50),@category_name VARCHAR(50)
,@category_type VARCHAR(30),@category_id int
,@category_type_i int
SELECT @jobname = 'powershell',@category_calss = '',@category_name='',@category_type = ''
SELECT @category_calss = CASE WHEN tshc.category_class = 1 THEN 'JOB'
WHEN tshc.category_class = 2 THEN 'ALERT'
else 'OPERATOR'
END
, @category_type = CASE WHEN tshc.category_type = 1 THEN 'LOCAL'
WHEN tshc.category_type = 2 THEN 'MULTI-SERVER'
else 'NONE'
END
,@category_name = tshc.name
,@category_type_i = category_type
,@category_calss_i = tshc.category_class
