REM 取当前系统时间,可能因操作系统不同而取值不一样 
set CURDATE=%date:~0,4%%date:~5,2%%date:~8,2%
set CURTIME=%time:~0,2%
REM 小时数如果小于10，则在前面补0 
if "%CURTIME%"==" 0" set CURTIME=00 
if "%CURTIME%"==" 1" set CURTIME=01 
if "%CURTIME%"==" 2" set CURTIME=02

REM 设置所有者、用户名和密码 
set OWNER=owner
set USER=user

REM 创建备份用目录，目录结构为backup/YYYYMMDD/ 
if not exist "oracle_backup"                     mkdir oracle_backup
if not exist "oracle_backup\%CURDATE%"          mkdir oracle_backup\%CURDATE%
set CURDIR=oracle_backup\%CURDATE%
set FILENAME=%CURDIR%\%OWNER%_%CURDATE%_%CURTIME%.dmp
set EXPLOG=%CURDIR%\%OWNER%_%CURDATE%_%CURTIME%_log.log
REM 调用ORACLE的exp命令导出用户数据 
exp %USER%/%PASSWORD%@sid log='%EXPLOG%' file='%FILENAME%' owner=(%OWNER%)
