Antonio, At this point, you may wish to open an ETR to IBM to identify why your files are growing so quickly. I would not think it should grow that fast unless there is a lot of backup functions running.
How many volumes/datasets do you do HSM backup for? It maybe that 4320 Cylinders is insufficient for your DFHSM Backups. We do not do many. We have daily full volume dumps for our critical system/application files. We typically use DFHSM backups for TSO and Roscoe pools. Not much else. I am not sure if there is a rule of thumb as to what makes good candidate volumes for backup. Maybe others might have a suggestion.
