hello Sagar
when you use RMAN for backup you can set RETENTION POLICY for window of day or redundancy for example
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS;
or
RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 3;
and when you backup use "BACKUP ... PLUS ARCHIVELOG" for example
BACKUP DEVICE TYPE sbt
DATABASE PLUS ARCHIVELOG;
it cause that RMAN when backup your database , backup your archived logs too ;
and about that two first CONFIGURE command
first command cause backupfiles and archived log files that backuped up before than 3 days signed obsolete in V$BACKUP_FILES view
(you can query the V$BACKUP_FILES view and check the OBSOLETE column)
second command cause backupfiles and archived log files that backuped up 3 times signed obsolete in V$BACKUP_FILES view
and if you use "DELETE OBSOLETE ..." command in RMAN it delete obsolete files
and your archived logs that backued up and are obsolete will be delete
AND you can use DBMS_SCHEDULER for synchronize this routine
