SQL Server下利用vbscript 实现数据库月备份自动清理并发邮件提醒
---Summary---
这份文档其实主要是讲vbscript的文件处理和在vbscript 下如何发邮件。大至分为三个部分。
一．Sql Server 数据库备份
二．Sql Server 调用vbs对数据库备份文件夹进行扫描，清理以前旧的数据库备份，只保留当前月的数据库备份。
三．将清除的数据库备份文件以附件的形式通知数据库管理员。
---Detailes---
1. Sql Server 数据库备份，以Job 的方式来实现，数据库备份文件名以日期的格式命名。
Step Name: Bakup Training DB
Type: Transact-SQL Script(T-SQL)
Database: ASATTraining
Command:
declare @filename nvarchar(100)
set @filename='D:/TRSYS_DB_BAK/'+convert(char(10),getdate(),112)
print @filename
BACKUP DATABASE [ASATTraining] TO DISK = @filename WITH NOINIT , NOUNLOAD , NAME = N'ASATTraining', NOSKIP , STATS = 10, NOFORMAT
2. Sql Server 调用vbs实现清理上个月的备份文件，写清理日志，发邮件。
1).数据库文件和清理日志文件夹
2).清理数据库日志的程序文件夹,下面就分别讲讲这个文件夹内每个文件的具体用途。
i)Email 里有一个Email_List.txt 的文件，它是记录邮件接受者的用件地址。
每行显示一个邮件地址，具体如下：
Email_List.txt
lilo.zhu@gmail.com
lilo.zhu@ymail.com
lilo.zhu@qq.com
ii)Log 内是清除数据库备文件时记录的日志文件，文件以系统日期.log 形式命名。
iii) Backup_Clear.bat 文件是供Sql Server 在job 是调用的。
Step Name: Run Clear Last Month Backup Database Data
Type: Operation System (CmdExec)
Run as: SQL Agent Service Account
Command: D:/TRSYS_DB_BAK_CLEAR/Backup_Clear.bat
Backup_Clear.bat
d:
cd d:/TRSYS_DB_BAK_CLEAR
Backup_Clear.vbs D:/TRSYS_DB_BAK
iv) Backup_Clear.vbs 是实现在清除非本月数据库备份文件，写清除日志，发送邮件的具体脚本程序,内容如下：
Backup_Clear.vbs

End Function
---Remark---
1. vbs 中发邮件是使用CDO.Message 这个对象。
2. Sql Server 调用带参数的bat 批处理容易出问题，最好将参数都写在bat 文件内，Sql Server 只需调用这个bat 批处理文件就行了。
