CMD常用命令02定期备份Oracle – Neohope的网络笔记

项目实施后，为了以防万一，决定每天夜里备份数据库
虽然Oracle本身就有自动备份的功能，但我仍然不放心于是用bat和windows的任务计划进行了备份

set FilePath=S:/Backup/
set UserName=user
set PassWord=pwd
set ServiceName=orcl

if not exist "%FilePath%" (exit)

set FileName=%DATE:~0,10%-%TIME:~0,8%
set FileName=%FileName::=-%

set FileName=%FileName: =0%
set DBFile=%FilePath%%FileName%.dmp
set LogFile=%FilePath%%FileName%.log

echo ORACLE数据库备份开始
echo %DATE:~0,10% %TIME:~0,8%
echo ORACLE数据库备份数据保存到%DBFile%
echo ORACLE数据库备份日志保存到%LogFile%

exp %UserName%/%PassWord%@%ServiceName% file=%DBFile% log=%LogFile% compress=y direct=n rows=y 
owner='%UserName%' consistent=n constraints=y grants=y indexes=y triggers=y

另外又加了个定期删除的bat，但这个有些问题的，就是只考虑了备份文件的创建时间，并没有考虑到要保留几个备份
换句话说，当连续7天备份失败后，就没有备份了，所以请修改一下再用
