| 摘 要： | 数据备份是防范数据库灾难的重要手段,也是防止Oracle数据库发生介质故障的惟一方式.校园数据中心采用Oracle 10G RAC架构和主/备数据库异地冗灾的方式进行部署,由备数据库对主数据库实施备份操作,探索了Oracle10G数据泵做逻辑备份与RMAN工具进行归档模式下的增量备份相结合的备份策略,通过Unix的cron进程自动快速备份Oracle数据库,保证了数据备份的可靠性和可用性.

| Abstract: | Data backup is very important measure to keep database away from calamity,and it is the only way to prevent the medium failure of Oracle database.The campus data center adopts Oracle 10G real application cluster fabric and primary/standby database data guarding lay in different place,standby database backup the primary database.Discussed the backup policies that logical backup database by Oracle 10 data pump and incremental backup in archiving mode by recovery manager.Automatic and fast backup database by Unix cron process,ensure the dependability and usability of data backup. |
