采用0221222增量備份策略,7天一個輪回

也就是周日0級備份，周1 2 4 5 6 采用2級增量備份，周3采用1級增量備份

打開控制文件自動備份

CONFIGURE CONTROLFILE AUTOBACKUP ON;

配置控制文件備份路徑

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

將過期天數設為7天

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