    D. CONFIGURE DEVICE TYPE DISK BACKUP TYPE COMPRESS

    E. BACKUP DATABASE COMPRESS

    Answer: C

    答案解析:

    参考:http://docs.oracle.com/cd/E11882_01/backup.112/e10643/rcmsynta010.htm#RCMRF90087



    BACKUP TYPE TO
       [[COMPRESSED]
       BACKUPSET | COPY]
    Configures the default backup type for disk or tape backups. For SBT devices the COPY option is not supported. The default for disk is BACKUPSET.

    If BACKUP TYPE is set to BACKUPSET, then the BACKUP command always produces backup sets regardless of which media the backup is created on. With the COMPRESSED option, the backup sets produced use binary compression.

    The default location for disk backups is the fast recovery area, if one is configured; otherwise, RMAN stores backups in a platform-specific location. The default format for backup file names is %U.
