Windows下oracle自动备份，编写1.bat批处理文件
set year=%date:~0,4%
set month=%date:~5,2%
set day=%date:~8,2%
set dbback=%year%%month%%day%
exp hbskjt_oa_0121/password file=d:\temp\%dbback%.dmp owner=hbskjt_oa_0121 log=d:\temp\%dbback%.log
cd \
cd Program Files\WinRAR\
Rar.exe a -k -r -s -m3 d:\back\db_%dbback%.rar  d:\temp\%dbback%.*
Rar.exe a -k -r -s -m3 d:\back\web_%dbback%.rar d:\gx\tomcat-6.0.26\webapps\oa
del /f/s/q d:\temp\%dbback%.*
然后用计划任务执行1.bat文件。
