While you could query the BACKUPS or CONTENTS tables via SQL on the SP server-side, my experience is that this is no faster than QUERY BACKUP on the client-side, and a lot more resource-intensive for the SP server. An alternative would be to set these variables in your mmbackup shell environment:
export MMBACKUP_DSMC_BACKUP="-auditlogging=full -auditlogname=/var/log/dsm-audit-_node-name_-_fs-name_-backup.log" export MMBACKUP_DSMC_EXPIRE="-auditlogging=full -auditlogname=/var/log/dsm-audit-_node-name_-_fs-name_-expire.log" You'll get messages like this in those files: 09/09/22 05:26:51 ANS1651I Backed Up: /gpfs/foo/bar 09/09/22 05:26:51 ANS1651I Failed: /gpfs/foo/invalid_name 09/07/22 20:50:48 ANS1657I Expired: /gpfs/foo/deleted_file With a bit of work you can parse together what happened when as mmbackup runs.
