Ulrich, While I agree with you that backups to tape should be allowed, if a backup fails to ML1 due to lack of space won't the request fail and the next backup in the queue be executed? That is what I would expect.

IMHO ... Yes, but ... What if a dataset backup request exceeds 850MB or the max. space available on a single ML1 disk? Since you don't allow tape to be used for backups, this will cause an error and your dataset backups will be held again. My recommendation is to first change your configuration to allow one (or more) tape backup tasks and then release backup.

I will take a closer look at this option. Since the DATASET BACKUP option is held, can I assume if I issue the RELEASE BACKUP(DSCOMMAND), the datasets will be backed up to ML1 DASD since the TAPE(TASKS is set to (0). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
