Re: Compression/Compaction on Save to Virtual Tape

[Kirk Goins <kirkgoins@xxxxxxxxx>]

I'm not so concerned on what happens when it goes to tape as I am about the
amount of disk I need in the partition to support the initial save. I will
see how well *YES performs shortly.  In the past I have used CLs that
Create/used savefiles to do the first save and found *MEDIUM was a good
combo of resources needed and the resulting amount of disk needed.
