failed restoring points in the appdata directory

i've had problems with my 100GB disk filling up, while only having 20GB of files.
tonight my nextcloud docker instance got auto-upgraded over night and was defunct in the morning.
i restarted the containers, the disk usage went from 97% to 84% (i guess logs that didn't survive the restart?)

i noticed the backup app folder

34G     data/appdata_xxxxxxxxxxxx/backup

is bigger than my files + db

20G     data/username
8.5G    db

so i had a peek into the backup folder and found:

i configured the backup app via the web gui, and set

Limit restoring points creation to the following hours interval: 01:00 and 06:00

Time interval between two full restoring points: 3 days
Time interval between two partial restoring points: 1 day

the web gui also shows me the same as this command:

so is this normal? can i provide more logs from somewhere? i did turn off automatic backup creation for now...

i originally configured everything with external storage (in v1.0.0), after the upgrade to v1.0.3 i configured the appdata to be stored locally. i guess something got messed up? can i just remove & reinstall the app and start fresh?

PS: thanks for the app, i finally backed my stuff up. i dont only want to complain, i really appreciate the work that goes into creating this, thank all of you!

Review the web GUI backup settings and the ./occ backup:point:list output, comparing local and external restoring points after the v1.0.0-to-v1.0.3 storage change. Gather backup-app logs for the failed or incomplete points; done means explaining whether the extra local points and storage growth are expected and documenting a safe supported recovery path.
