Backup function disappeared in AMS

Why has the backup function disappeared from the dashboard? I have been trying to make a backup to a USB SSD over the network for almost 24 hours now. The limiting factor is the slowness of the transfer over the network. Why can’t I connect my USB disk to the Antipodes so that a backup can be made directly via the Antipodes file manager?

I previously had a RheinZ1 where the backup function was 100 times faster than the backup I am trying to make now.
A real miss by Antipodes.
