Subject: Virtual tape
To back up 100G of DASD to virtual tape, would you need 100G of DASD for the
virtual tape? Or possibly a better question: Does virtual tape utilize
compression, thus not requiring quite as much space as if data was simply
copied disk to disk?
How would the size be calculated?
How does virtual tape compare to using a save file or multiple save files?
