Bob, I last ran applyincremental 4-5 years ago at DR so it's possible that changes in the intervening years caused us to have differing experiences. With newer tape, disk and Ficon I would expect today's performance to be much better, except we can't assume the latest and greatest in Ginnie's environment. I don't think she gave us that info.
Five years ago I also ran Autodump daily on my ML1 volumes and used Recover to restore them at DR. That was painful. Perhaps there was a maxrecover that I failed to change but while the apply incrementals ran 15 abreast, the volume recovers to my dismay were single threaded. It took 5 hours to restore 15 ML1 volumes. We quickly changed to daily DSS Backups for ML1.

I have not performed an applyincremental in over 10 years. It WAS painful then and it was HRECOVER volume *with* applyincremental. Maybe the current HSM, tape technology and ESCON/FICON channels have made part of the process less painful. If so, great! Running AUTODUMP is definitely a better idea if the requirement is strictly for DR.

I believe you indicated that the data was already in a separate Storage Group. Bob, Hrecover volume commands take waaayyy too long. I have used Hrecover applyincremental fromdate(dd/mm/yyyy) and found it quite efficient. Recovers ran 15 concurrent and finished relatively quickly. I suspect it depends on how much data you're trying to recover. Snipped.....
