Metadata about the RMAN backup jobs

Hi All,

Greetings of the day. Hope everyone are doing great.

Have a doubt similar to one in the thread https://forums.oracle.com/forums/thread.jspa?threadID=2521794

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time        integer     7

and

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 35 DAYS;



Trying to get historical view of the backups for the past two months from tables

V$BACKUP_SET
V$BACKUP_SET_DETAILS
V$RMAN_BACKUP_JOB_DETAILS
V$RMAN_OUTPUT

The tables have information about backups for past 38 days. 11 days backup information from last month and 28 days of backup information of this month.
