数据库自动备份并删除30天前的备份文件

1、创建备份数据库的存储过程 -- ============================================= -- Create basic stored procedure template -- ============================================= -- Drop stored procedure if it already exists IF EXISTS ( SELECT * FROM

1、创建备份数据库的存储过程

-- =============================================
-- Create basic stored procedure template
-- =============================================

-- Drop stored procedure if it already exists
IF EXISTS (
SELECT *
FROM INFORMATION_SCHEMA.ROUTINES
WHERE SPECIFIC_SCHEMA = N'dbo'
AND SPECIFIC_NAME = N'SP_BackUpPortal'
)
DROP PROCEDURE dbo.SP_BackUpPortal
GO

CREATE PROCEDURE dbo.SP_BackUpPortal
@backFolderPath varchar(256)='D:/BackUp/Portal'
as
declare @today datetime
declare @todayString varchar(50)
declare @bakfilePath varchar(256)
declare @datenameString varchar(50)
set @today=getDate()
set @todayString=convert(varchar(11),@today,120)
select @datenameString= datename(dw,getdate())
-----If today is Sunday then do a full backup
if(@datenameString='Sunday')
begin
set @bakfilePath=@backFolderPath+'/Portal'+@todayString+'Full.bak';
backup database WSS_Content
to disk=@bakfilePath
end
------Else do a increment backup
else
begin
set @bakfilePath=@backFolderPath+'/Portal'+@todayString+'Increment.bak';
backup database WSS_Content
to disk=@bakfilePath
with DIFFERENTIAL
end
GO

2、创建调用比处理文件

echo Backup database daily, if the day is sunday do a full back up else do a Increment backup
SQLCMD.EXE -S Server/Instance -d DataBaseName -Q "exec dbo.SP_BackUpPortal "

Echo delte the backfile which generated before 30 days

FORFILES /P D:/BackUp/Portal /D -30 /c "cmd /c del @path"

if %date:~0,3%==Sun goto BackByMossCmd
Exit
:BackByMossCmd
echo Backup by the mosscmd
cd C:/Program Files/Common Files/Microsoft Shared/web server extensions/12/BIN
C:
STSADM.EXE -o backup -url http://mossSite/ -filename D:/BackUp/Portal/MossCmdPortalBack%date:~10,4%-%date:~4,2%-%date:~7,2%.bak
Exit

3.在批处理中添加删除30天前的备份文件脚本

FORFILES /P D:/BackUp/Portal /D -30 /c "cmd /c del @path"

4.新建windows计划任务

不用我说了吧
