Gotcha!
Do me a favor please … take a look at /home/user-data/backup/encrypted/ and also your backup directory … make a note of what is there, and then look again in a few days.
People are seeing and reporting oddities such as the backups saving each file in a directory and duplicating themselves, etc.
Personally, I don’t trust the rsync built into MiaB. I much prefer pulling myself via a cron job and rsync from the backup server.
