@David_Music , i assume you are making reference to your other post BUG - ZFS with virtual sub client - Manual incorrect
To be honest, i have not been affected by that. My screenshots above shows the folder structure that urbackup creates on my system and it doesn’t have square brackets.
Now, i only do image backups. Maybe the square brackets problem is exclusive of file backups and that would be why it is not affecting me. But that is pure speculation on my end.
Anyway, so far, urbackup is working properly on my Truenas Scale system with ZFS snapshots.
