[gpfsug-discuss] mmbackup against snapshot backup failing

[Ahmed Nasr]

Good Day,

this is my first time posting. it is great to talk to everyone here.
so i have an issue where mmbackup is not working properly and i don't know why.
Problem: mmbackup doesn't find any files that are eligible for backup. i used to work with dsmc and it is working fine but i want to employ the snapshot option within mmbackup.
here are my steps:

  1.  backup to tsm with mmbackup using the full backup option . that took around one month
  2.  tried to do an incremental backup with mmbackup against a snapshot (Failed)
  3.  tried to rebuild shadow database then backup but that failed as well
  4.  tried dsmc incremental which found eligible files and worked

i want to use snapshots which seems to be problematic

please let me know if you have any recommendations or ideas

command used:

mmbackup /gpfs/mariana/home/ -S home_snapshot_2024-01-25-09-23 -t incremental -L 2 -d --scope inodespace -v

Do the TSM include/exclude rules exclude all contents of /gpfs/mariana/home for TSM server gv-backup ?
