环境：windows Server 2003 oracle 10g,系统间备份
目标系统创建共享文件，原系统挂载共享目录
写批处理脚本，用任务计划定时调用
Rem * 由于系统实时性要求不是很高，数据量不大，且只有一块磁盘，考虑异地备份 *
Rem * 异地备份的时候使用expdp 出schema THUNIITSMUSER *
Rem * 使用windows命令的共享文件模式，将dump出来的文件copy到192.168.1.47上 *
Rem * create or replace directory dump_dir as 'E:\itsm_backup\dump_dir'; *
Rem * 'copy /y E:\itsm_backup\dump_dir*.* \\Shouhou47\itms_databak\'; *
Rem * 此脚本通过windows计划任务每个工作日23:05调用, *
Rem * 保留7天的备份，七天之前的备份删除掉 *
