I know that by default, one backup set contains only one backup piece.
So, I wonder how can I change that default number to be greater than 1?
I ask, because, as below, you can see that for one time backup, RMAN created two backupset.
And I want it to create one backupset instead:
RMAN> list backup summary;
List of Backups
===============
Key TY LV S Device Type Completion Time #Pieces #Copies Compressed Tag
------- -- -- - ----------- --------------- ------- ------- ---------- ---

4 B F A DISK 06-NOV-10 1 1 YES TAG20101106T182618
Any help would be appreciated.
Thanks
