OK, I found that teams are supported with the '--organizations' switch.
There is one small bug in the organizations.
The folder 'me' contains always all 'Boards'. Hence if a board 'Board 1' belongs to the organization/team 'Team 1' this board shows up in the backup two times.

└── me
...└── Board 1
└── team 1
...└── Board 1
This increases the amount of downloaded data big time.
