Hi
@janbu, thanks for joining the Community!
While we can't assist with a third party service like rsync, it is possible to see if your Dropbox Business plan is using unlimited version history.
You can check this from the admin console, and using
this specific link, or just search for 'Accepted/opted out of extended version history'.
Bear in mind, you'll need to change the dates to when this occurred, so I would go back to the beginning of 2017, which is when the changes were announced.and the option to keep UVH was made.
I'll leave the thread open so other users can assist with the rsync settings.
