This is not true. You can backup the data fine even if it is activated on the BES. You cannot restore certain databases when the device is activated on the BES. As you said, they're grayed out.
There's a way around that as well. Delete the Desktop [SYNC] service book. Then all the items will be available. Once you restore, then undelete the service book or resend it from the server.
If the device has been wiped, there shouldn't be any issue restoring the data.
