Ubuntu系统下的Oracle数据库备份策略主要依赖于Oracle提供的备份和恢复工具,如RMAN(Recovery Manager)和导出/导入(EXP/IMP)工具。以下是一些常见的备份策略和步骤:
RUN {
ALLOCATE CHANNEL ch1 DEVICE TYPE disk;
BACKUP AS COMPRESSED BACKUPSET DATABASE PLUS ARCHIVELOG;
RELEASE CHANNEL ch1;
}
RUN {
ALLOCATE CHANNEL ch1 DEVICE TYPE disk;
BACKUP INCREMENTAL LEVEL 1 DATABASE PLUS ARCHIVELOG;
RELEASE CHANNEL ch1;
}
RUN {
ALLOCATE CHANNEL ch1 DEVICE TYPE disk;
BACKUP DIFFERENTIAL DATABASE PLUS ARCHIVELOG;
RELEASE CHANNEL ch1;
}
