sqlserver 自动备份，压缩，删除多余备份文件

在D盘建立文件夹bak

--第一步： 创建自动备份作业脚本代码如下（可以直接跑）：

USE msdb--管理sqlserver作业

GO

/****** Object:  Job [备份JSTMBS]    Script Date: 2016/8/22 16:08:29 ******/

BEGIN TRANSACTION

DECLARE @ReturnCode INT

SELECT @ReturnCode = 0

/****** Object:  JobCategory [Database Maintenance]    Script Date: 2016/8/22 16:08:29 ******/

IF NOT EXISTS (SELECT name FROM msdb.dbo.syscategories WHERE name=N'Database Maintenance' AND category_class=1)

BEGIN

EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'Database Maintenance'

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

END

DECLARE @jobId BINARY(16)

EXEC @ReturnCode =  msdb.dbo.sp_add_job @job_name=N'备份JSTMBS', 
@enabled=1, 
@notify_level_eventlog=0, 
@notify_level_email=0, 
@notify_level_netsend=0, 
@notify_level_page=0, 
@delete_level=0, 
@description=N'每天上午数据库备份', 
@category_name=N'Database Maintenance', 
@owner_login_name=N'jstmbsuser', @job_id = @jobId OUTPUT

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

/****** Object:  Step [每天备份]    Script Date: 2016/8/22 16:08:29 ******/

EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'每天备份', 
@step_id=1, 
@cmdexec_success_code=0, 
@on_success_action=1, 
@on_success_step_id=0, 
@on_fail_action=2, 
@on_fail_step_id=0, 
@retry_attempts=0, 
@retry_interval=0, 
@os_run_priority=0, @subsystem=N'TSQL', 
@command=N'declare @strDate nvarchar(max);

set @strDate = REPLACE( N''D:\bak\JSTMBS_backup_'' + Convert(nvarchar(10),getdate(),23) + N''.bak'',''-'',''_'')

 

BACKUP DATABASE [JSTMBS] TO  DISK = @strDate WITH NOFORMAT, NOINIT,  NAME = N''JSTMBS_backup-完整 数据库 备份'', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

GO', 
@database_name=N'JSTMBS', 
@flags=0

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

EXEC @ReturnCode = msdb.dbo.sp_update_job @job_id = @jobId, @start_step_id = 1

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

EXEC @ReturnCode = msdb.dbo.sp_add_jobschedule @job_id=@jobId, @name=N'每天备份', 
@enabled=1, 
@freq_type=4, 
@freq_interval=1, 
@freq_subday_type=1, 
@freq_subday_interval=0, 
@freq_relative_interval=0, 
@freq_recurrence_factor=0, 
@active_start_date=20160822, 
@active_end_date=99991231, 
@active_start_time=50000, 
@active_end_time=235959, 
@schedule_uid=N'f90cfdc3-cb5d-4e19-9e93-99b8921d36c1'

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

EXEC @ReturnCode = msdb.dbo.sp_add_jobserver @job_id = @jobId, @server_name = N'(local)'

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

COMMIT TRANSACTION

GOTO EndSave

QuitWithRollback:

    IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION

EndSave:

GO

第二步：压缩 

1.下载WinARA解压程序默认安装在c盘；

2.建立.bat文件，bak.bat 内容如下：

c:\Progra~2\WinRAR\WinRAR.exe a D:\bak\JSTMBS_backup_%date:~0,4%_%date:~5,2%_%date:~8,2% d:\bak\JSTMBS_backup_*%date:~0,4%_%date:~5,2%_%date:~8,2%.bak 

3.建立计划：控制面板——所有控制面板项——管理工具——任务计划——创建基本任务——操作——新建——程序或脚本——浏览——bak.bat

第三步：删除多余的压缩文件和备份文件：

1.创建vbs文件：autoDeleteOldBak.vbs ，内容如下：

const reMainCount = 1           '保留几day

Dim fso,dc,file,files,folder,subfolders,subfolder

set fso=createobject("Scripting.FileSystemObject")

set folder=fso.getfolder("D:\bak")

Dim today

today=Now

for each tempFile in folder.files

    dim arr

    arr=Split( tempFile,"_backup_")

    if UBound(arr)>0 then

        dim tempDate,diff

        tempDate=Cdate( Replace( Left(arr(1),10),"_","-"))

        diff= DateDiff("d",tempDate,today)

        if (diff>reMainCount) then

            fso.deleteFile(tempFile),true

        end if

    end if

next

set fso=nothing

2.创建autoDeleteOld.bat 文件，内容如下：

cscript D:/bak/autoDeleteOldBak.vbs

3.建立windows计划，防第二步。
