Just released v2.35.0 which should allow backup over RSD

Also, please note that using the backup doesn't require a tunnel and will work much faster without.

For the first problem, you'll have to first remove your old pair record:

# delete it
pymobiledevice3 remote delete-pair

As for the second, the backup process works in DIFF. meaning, you'll have to create a full backup first for it to work.

pymobiledevice3 backup2 backup --full /path/to/backup/directory
