| SESSION_KEY | NUMBER | Session identifier. Use in joins with RC_RMAN_OUTPUTandRC_RMAN_BACKUP_JOB_DETAILS. | 
| SESSION_RECID | NUMBER | Together with SESSION_STAMP, uniquely identifies output for this backup job fromRC_RMAN_OUTPUT. | 
| SESSION_STAMP | NUMBER | Together with SESSION_RECID, uniquely identifies output for this backup job fromRC_RMAN_OUTPUT. | 
| DB_KEY | NUMBER | The primary key for this database in the recovery catalog. Use this column to join with almost any other catalog view. | 
| DB_NAME | VARCHAR2(8) | The DB_NAMEof the database incarnation to which this record belongs. | 
| BS_KEY | NUMBER | The primary key of the backup set to which this record belongs in the recovery catalog. Use this column to join with RC_BACKUP_SETorRC_BACKUP_PIECE. | 
| RECID | NUMBER | The backup set RECIDandSTAMPform a concatenated primary key that uniquely identifies this record in the target database control file. | 
| STAMP | NUMBER | The backup set RECIDandSTAMPform a concatenated primary key that uniquely identifies this record in the target database control file. | 
| SET_STAMP | NUMBER | The SET_STAMPvalue fromV$BACKUP_SET.SET_STAMPandSET_COUNTform a concatenated key that uniquely identifies this record in the target database control file. | 
| SET_COUNT | NUMBER | The SET_COUNTvalue fromV$BACKUP_SET.SET_STAMPandSET_COUNTform a concatenated key that uniquely identifies this record in the target database control file. | 
| BACKUP_TYPE | VARCHAR2(1) | The type of the backup: D(full backup or level 0 incremental),I(incremental level 1),L(archived redo log). | 
| CONTROLFILE_INCLUDED | VARCHAR2(7) | Possible values are NONE(backup set does not include a backup control file),BACKUP(backup set includes a normal backup control file), andSTANDBY(backup set includes a standby control file). | 
| INCREMENTAL_LEVEL | NUMBER | The level of the incremental backup: NULL,0, or1. | 
| PIECES | NUMBER | The number of backup pieces in the backup set. | 
| START_TIME | DATE | The time when the backup began. | 
| COMPLETION_TIME | DATE | The time when the backup completed | 
| ELAPSED_SECONDS | NUMBER | The duration of the backup in seconds. | 
| BLOCK_SIZE | VARCHAR2 | The block size used when creating the backup pieces in the backup set. | 
| KEEP | VARCHAR2(3) | Indicates whether this backup set has a retention policy different from the value for CONFIGURE RETENTION POLICY. Possible values areYESandNO. | 
| KEEP_UNTIL | DATE | If the KEEP UNTIL TIMEclause of theBACKUPcommand was specified, then this column shows the date after which this backup becomes obsolete. If the column isNULLandKEEP OPTIONSis notNULL, the backup never becomes obsolete. | 
| KEEP_OPTIONS | VARCHAR2(11) | The KEEPoptions specified for this backup set. Possible values areNOLOGS,BACKUP_LOGS,LOGS, andNULL.NOLOGSindicates a consistent backup made when the database was mounted.BACKUP_LOGSindicates that the backup was made in open mode, so archived log backups must be applied to make it consistent.LOGSindicates a long-term backup made with theLOGSkeyword, which is now deprecated.NULLindicates that this backup has noKEEPoptions and becomes obsolete based on the retention policy. | 
| DEVICE_TYPE | VARCHAR2(255) | Device type on which the backup is stored. If the backup set is stored on multiple types of devices (for example, if a backup set created on disk and still present on disk has also been backed up to tape using BACKUP BACKUPSET), then this column contains an asterisk (*). Values areDISKorSBT_TAPE. | 
| COMPRESSED | VARCHAR2(3) | YESif RMAN's binary compression was used in creating the backup set.NO, otherwise. | 
| NUM_COPIES | NUMBER | Number of identical copies of this backup set created during the backup, for example if duplexing was used. | 
| OUTPUT_BYTES | NUMBER | Sum of sizes of all output pieces generated by this job. | 
| ORIGINAL_INPUT_BYTES | NUMBER | Sum of sizes of all input files backed up for this job. | 
| COMPRESSION_RATIO | NUMBER | Compression ratio for this backup. | 
| STATUS | CHAR(1) | The status of the backup set: always A(all backup pieces available), because this view only reflects available backup sets. | 
| ORIGINAL_INPRATE_BYTES | NUMBER | Number of bytes read each second when the backup set was initially created. | 
| OUTPUT_RATE_BYTES | NUMBER | Number of bytes written each second when the backup set was initially created. | 
| ORIGINAL_INPUT_BYTES_DISPLAY | VARCHAR2(4000) | Same value as ORIGINAL_INPUT_BYTES, but converted to a user-displayable format, for example, 798.01M or 5.25G. |

| ORIGINAL_INPRATE_BYTES_DISPLAY | VARCHAR2(4000) | Same value as ORIGINAL_INPRATE_BYTES, but converted to a user-displayable format, for example, 798.01M or 5.25G. | 
| OUTPUT_RATE_BYTES_DISPLAY | VARCHAR2(4000) | Same value as OUTPUT_RATE_BYTES, but converted to a user-displayable format, for example, 798.01M or 5.25G. | 
| TIME_TAKEN_DISPLAY | VARCHAR2(4000) | Same value as ELAPSED_SECONDS, but converted to a user-displayable format in hours, minutes and seconds. |
