MSSQL 自动备份

1、创建一个作业

 2、维护步骤

 3、步骤脚本

declare @filename varchar(1024)
declare @path varchar(1024)
set @path = N'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\';
declare @extension_name varchar(16)
set @extension_name = N'bak';
set @filename = 'YourDataBase_'+convert(varchar(1024), getdate(), 120)
set @filename = replace(@filename, ':', '')
set @filename = replace(@filename, '-', '')
set @filename = replace(@filename, ' ', '')
set @filename = @filename + '_' + convert (varchar(3), datepart(ms, getdate())) + N'.' + @extension_name
-- 得到完整目标文件，数据库将备份到这个中
set @filename = @path + @filename
-- select @filename

-- 开始备份, MYDB 是需要备份的数据库, COMPRESSION 参数表示压缩，可节省磁盘空间
backup database YourDataBase to disk = @filename with noformat, noinit, name = N'YourDataBase', skip, norewind, nounload, stats = 10, COMPRESSION

-- 删除15天前的备份文件
declare @olddate datetime
select @olddate=getdate()-15
-- 执行删除 (SQL 2008 具备)
execute master.dbo.xp_delete_file 0, @path, @extension_name, @olddate, 1
go

 4、计划设定
