Dataset backup process not updating LBACKUP date in catalog entry It is showing zeros.

Products

• Disk Backup and Restore - MVS

Issue/Introduction

1) Users are backing up datasets, and the LBACKUP date in the catalog entry is zeros, indicating no backup done. Is there a Disk Backup configuration option set incorrectly? Or is this working as designed?

2) Does Disk check management class ADMIN OR USER COMMAND BACKUP attribute? We're thinking of changing those for another product.

Resolution

1) Yes, it is normal to have zeros. (Additionally, LISTCAT will provide LBACKUP details only for SMS managed datasets). Refer to the LISTD report if backup details are needed for any particular dataset from DISK.

Also the technical reason for leaving LBACKUP date as zeros is because it's an IBM used field. This way Disk will be able to work with both Disk and HSM in the same environment.  Disk won't change it in case HSM does.

2)See section SMS and BACKUP in the USING Guide which has a section that states as following:

Admin or User Command Backup (MC)

This required field can be defined BOTH, ADMIN, or NONE. The default is BOTH. When this field is defined BOTH, both the Storage Administrator and the user can explicitly back up a data set. When this field is defined ADMIN, only the Storage Administrator can explicitly back up a data set. When this field is defined as NONE, neither can explicitly back up. To define a Storage Administrator to Disk, use the SMSSTGAD sysparm.
