RE: question on rman backup incremental level 0

- Is this because RMAN level 0 backup only backs up the blocks that have been written, and escapes empty blocks in data files?
2. How does RMAN determine which datafiles to group together, to create different backupsets?
>>> I'm not positive on this, but IIRC it tries to size them evenly,
e.g. if you have 2 backup sets and have one 100GB datafile and 4 25GB datafiles, it will put the 100GB datafile in one backupset and the other 4 files in the other backupset.
