Hallo Ahmend,
at first to understand mmbackup: you should know that mmbackup use a fs or independend fileset snapshots (--scope) to compare the content of shadow db with the generated snapshot. This compare generated filelist that are then used to make a selective backup over dsmc.
To generate these mentioned snapshot you must paramized mmbackup with -S. If you had trouble you should run at first a rebuild oft he shadowdb with --rebuild.
I think a backup over a snapshot itself doesnt work.

Betreff: [gpfsug-discuss] mmbackup against snapshot backup failing
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 ?
