Depending on the environment, that might not be a requirement. For my work config, I've got plenty of holdingdisk space, and my main need is a short backup window, and the time to tape is not really a concern (although I don't want it to run ALL day). On my home systems I don't really care if it takes all day, as long as it finishes. YMMV, of course. I realize that many people using vtapes may not be using a holding disk due to possible I/O contention issues, but if you are using slow 'disks' then perhaps a holdingdisk would make sense.
