Hello Wayne,
What was the total size for the 222,000 IFS objects ? Our 3.8 million objects take up about 100gb.
If your 222,000 objects are only about 11gb, I would have expected just a few minutes to back them up if the tape drive was running at close to rated speeds.
I think it's the large number of small objects that is killing performance because the tape drive probably never gets into streaming mode.
However this is pure speculation since I'm still learning the 3581 :-)
Regards,

Our last backup of 222,000 IFS objects took 37 minutes with a 3582 tape library HVD-attached to a Model 740, so 8 to 9 hours sounds right. One suggestion, if you have enough DASD, is to try saving the images to a save file and then saving the save file to tape.
