导读:1建站知识这篇文章主要介绍了linux自动运行rman增量备份脚本，实现周日和周三凌晨1:00执行0级全库备份，周一、二、四、五、六企业网站建设网站seo优化培训。

一、增量备份脚本0级备份脚本：红色部分为自定义的备份文件放置的目录

复制代码 代码如下:

#script.:BackupFull.sh#creater:xyh#date:2014-03-08#desc:backup full database datafile in archive with rman#connect databaseexport ORACLE_BASE=/u01/app/oracleexport OR百度seo网站优化ACLE_SID=orclexport ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1export PATH=$ORACLE_HOME/bin:$PATHrman target/ << EOF_RMANrun{allocate channel c1 type disk;backup incremental level 0 tag 'db0' format'/home/oracle/RmanBackup/db0_%d_%T_%s' database include current controlfile;sql 'alter system archive log current'; backup filesperset 5 format '/home/oracle/Rm建设网站anBackup/cf0_%d_%T_%s' archivelog all delete input; #filesperset 5表示备份集里面最多包含5个文件  delete noprompt obsolete;release channel c1;}# end

1级备份脚本

复制代码 代码如下:

#script.:Incrl.sh#creater:xyh#date:2014-03-08#desc:backup full database datafile in archive with rman#connect databaseexport ORACLE_BASE=/u01/app/oracleexport ORACLE_SID=orclexport ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1export PATH=$ORACLE_HOME/bin:$PATHrman target/ << EOF_RMANrun{allocate channel c1 type disk;backup incremental level 1 tag 'db1' format'/home/ora网站建设cle/RmanBackup/db1_%d_%T_%s' database include current controlfile;sql 'alter system archive log current'; backup filesperset 5 format '/home/oracle/RmanBackup/cf1_%d_%T_%s' archivelog all delete input; #filesperset 5表示备份集里面最多包含5个文件  delete noprompt obsolete;release channel c1;}#end

二、使用linux的crontab设置自动执行备份

复制代码 代码如下:

crontab -e

按Enter后，可以像vi编辑器一样输入下面内容

复制代码 代码如下:

0 1 * * 0 /home/oracle/BackupFull.sh >>/home/oracle/BackupFull.log0 1 * * 3 /home/oracle/BackupFull.sh >>/home/oracle/BackupFull.log30 1 * * 1-2 /home/oracle/Incrl.sh >>/home/oracle/Incr.log30 1 * * 4-6 /home/oracle/Incrl.sh >>/home/oracle/Incr.log

查看crontab内容：crontab -l注：上面意思是把全库备份日志写到/home/oracle/BackupFull.log文件中，而增量备份日志写到/home/oracle/Incr.log中周日和周三凌晨1:00执行0级全库备份，周一、二、四、五、六凌晨1:30执行增量备份
