Hi

Total Data files size is 485 GB but from Legato Networker tape backup, the size is around 420 GB!

The RMAN backup is not a compressed backup. So, then what makes this huge difference?

Thanks in advance.

RMAN does not backup blocks that have never been used (that is above the HWM of each file).
