We are working on a DR process. I notice that the defaults for a Hidro backup include the PACK option which tells Hidro to pack, or condense in some fashion, its output. The output is being written to 3590E drives. It appears that there are three choices we can make for condensing the data: software only, hardware only, or a combination of the two (uncompacted was purposely omitted from the list). Which is likely to give the best results? Does software compaction produce consistently lower output volumes than letting the drive do it? Is there anything to be gained by using both h/w and s/w? Obviously, software compaction costs in terms of cpu time. The question is, is it worth the time spent?
