In my understanding the space requirements are the same. It takes a little longer to process because each day's incremental is injected into the full backup from the day before, creating a new full backup. The full backup from the day before is then deflated into an incremental.
It looks like this:
incr → incr → incr → full
Where normal incremental looks like this
full → incr → incr → incr
We're running reverse incrementals because restores usually happen to be from the latest backup available. If that's a full then the restore time is pretty quick.
Also files to tape is definitely still an option because we're using it in 9.5
