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.

Hello All,

We are starting to use a 3581 LTO-2 tape drive to back up 100gb of image files (3.7 million 50-60kb images) for a customer and we have noticed that this process takes about 8-9 hours. Backing up a small number of large files is much faster.

Does anyone here know if there is a way to tune the 3581 so that it will stream even when backing up large amounts of small files ?

Any input is appreciated.
