Goal
In this document, I will list some methods for deleting rman backupset.
NOTE: In the images and/or the document content below, the user information and environment data used
represents fictitious data from the Oracle sample schema(s),Public Documentation delivered with an
Oracle database product or other training material. Any similarity to actual environments, actual
persons, living or dead, is purely coincidental and not intended in any manner.
For the purposes of this document, the following fictitious environment is used as an example
to describe the procedure:
Database/Instance Name = orcl11204
Directory = /refresh/home/app/11.2.0.4 and all subdirectories
Solution
For example, we have some backup, which can be confirmed via "list backup" command:
RMAN> list backup;

Please allow me to list the following methods:
Method 1:
delete backupset <backupset number>;
eg:
RMAN> delete backupset 1;
Method 2:
delete backupset tag <tag number>;
eg:
RMAN> delete backupset tag=TAG20181024T085438;
Method 3:
You can also delete backupset those backed up before a particular time:
delete completed before "TO_DATE('Date String','MM/DD/YYYY HH24:MI:SS')";
For example:
delete backup completed before "TO_DATE('09/23/2018 08:00:00','MM/DD/YYYY HH24:MI:SS')";
And also, if backupset file is deleted by OS command, then you can delete related information via RMAN by using "force".
eg:
RMAN> delete force backupset 1;
RMAN> delete force backupset tag=TAG20181024T085438;
RMAN> delete force noprompt backup completed before "TO_DATE('09/23/2018 08:00:00','MM/DD/YYYY HH24:MI:SS')";
Please note if recovery catalog is configured please ensure you connect to the recovery catalog when running the above commands
In your scenario you can use RMAN command "backup" to copy or move the backups/logs to any other location.See RMAN reference on BACKUP BACKUPSET
http://docs.oracle.com/cd/E11882_01/backup.112/e10643/rcmsynta007.htm#RCMRF90026
For example:
-- to copy backupset to FS according to TAG
backup backupset from tag 'TAG' to destination '/disk/BKP_COPY';
backup backupset from tag 'TAG' format '/disk/BKP_COPY/%U';
-- to copy according to TIME
backup device type disk backupset completed after "sysdate-1" format '/disk/BKP_COPY/%U';
-- to move backupset from ASM to FS
backup backupset from tag 'TAG' format '/disk/BKP_COPY/%U' delete input;
-- to move back to ASM
backup backupset from tag 'TAG' format '+BKP_DG' delete input;
-- monitor # of copies
list backupset summary;
-- monitor location
list backupset;
list backupset tag 'TAG';
