i have dropped many objects (tables and indexes ) of the total size of approx 10 GB.
However the size of the RMAN backup has not decreased. It is still the same. I am not using compress option as it takes a lot of time. Any other way to reduce the rman backup size.Please help..
Thanks in advance.

- Move your objects in new tablespaces and drop old ones.
- Export/drop objects/shrink files/import
