  • oracle全量、增量备份

    采用0221222增量备份策略,7天一个轮回

    也就是周日0级备份,周1 2 4 5 6 采用2级增量备份,周3采用1级增量备份

    打开控制文件自动备份

    CONFIGURE CONTROLFILE AUTOBACKUP ON; 

    配置控制文件备份路径

    CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/file/backup/rman/controlfile_%F'; 

    将过期天数设为7天

    RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS; 

    ---全备
