Hello biallas, (Mark?)
Just from the top of my head ...
- I believe, that the "... commenced... " message is NOT a respond to the BACKUP command, and therefore does not appear in the SDSF output. You might have to check the LOG.
- If you are running more than one z/os system, which share the same SECFILE, and you want more than one BACKUP per day, you might set different BACKUP times for each z/os system. Ensure that the backups do not overlap!
- consider to backup RECFILE more frequently, several times per day, or even create the recovery commands several times per day depending from your backup time.
- consider to copy the backups to a different device type apart from / additional to dasd, for example to tape/vts.
best regards,
Josef
