Hi Daniel, TYPE=AUTO is not a necessity. The majority of sites control when the full-volume vs. incremental backups are done by having two sets of control statements. One specifying TYPE=FDR to get the full-volume backups and the other specifying TYPE=ABR to get the incremental backups. This method gives the sites control as to when they want the full-volume backups to be done. TYPE=AUTO forces a full-volume dump whenever the cycle number reaches a specified value. TYPE=AUTO works for this as well except when a new volume is added and it is added midweek or if a rerun needs to be done for volumes due to some error.
For automated restores at a DR site, you probably want to look at FDRDRP to manage and multiple full-volume recovery tasks in parallel. FDRDRP manages the backup tapes and can pass allocated tapes to the other tasks as needed and will process all the files from a given tape before demounting it. Normal process of FDRDRP will also process the incremental based on what it in the ICF catalog at the time of the restore. If there are questions, please feel free to contact us at Innovation to discuss any of these questions.

We stack up to 15 volumes per 3590 in that process. Another EXEC generates restore JCL for use at DR. Now the DR maven wants us to look at FDRABR for incrementals and for the whole backup scenario in general. This would more than likely be a TYPE=AUTO with a weekly full dump and incrementals during the week. He is also interested in FDRAPPL to replace DRManager in use now. OK, here is my confusion. In my current process I have around 60 jobs to run at DR on the floor system. I simply restore the PDS containing those jobs and send them in. Now if we switch to FDRABR (AUTO) what is my course of action at DR? I've been combing through the manual but it's only opened up this type of question.
