I think the asynchronous I/O part is a bit tricky. The question doesn't provide enough information to determine if that's the case, but the parallel backup is a clear giveaway.

True, the focus seems to be on the parallel backup rather than asynchronous I/O.

I think the asynchronous I/O aspect is not as clear in this scenario.

Haha, the SQL command at the end is a nice touch. Gotta love those RMAN commands that do a little bit of everything!

I'm not sure about the compressed backup sets, but the use of multiple channels suggests that it's taking advantage of parallel processing to speed up the backup process.

The command definitely uses parallelization for the backup set. It's allocating three separate channels to handle different sets of datafiles concurrently.
