sql server 数据库的备份脚本（转）

由于工作需要我需要编写一个sql server 数据库的备份脚本.需要实现的功能是:
1. 能根据计划进行数据库的完全备份/增量备份.
2. 将不同的备份内容存放在不同的备份设备上.(例如每天备份的内容单独存放在一个备份设备上).
3.将备份的内容在其他的机器上面保存一份.
在网络上找了一些资料但是大多数都没有人写过类似的东西.经过我两天的编写和测试现在终于搞定了.
实现的功能是:
1.将需要执行的脚本放到计划任务当中.根据需要调整运行的时间.
2.每次的备份内容生成单独的设备名称用日期文件名进行判断.
3.将备份完的内容ftp到其他计算机上.这样也算是搞一个小的"异地容灾"不至于在一个机器完蛋后.数据库的备份没有了.
下面就是这两个脚本的内容.欢迎大家提供意见也建议.
另外就是本人不负责任何运行这些脚本的后果.但是有任何技术问题欢迎交流.如果是在我有时间和我知道的前提下.
脚本分为两部分1个是完全备份的.另外一个是差异备份的.
