Yes you can.
In Cumulus Configuration Internet under Weather Underground check 'Catch Up'.

Edit: Yes you can set Cumulus to do the catch up from whenever Cumulus is
shut down. But I likely misunderstood your question
. Cumulus does not retroactively upload when there has been a communication error or internet shut down and Cumulus was still running. I am not sure if it would by using one of the daily backup sets to roll back Cumulus, but that might duplicate uploaded data if more recent data has already been sent. Possibly someone else here will have an answer on this or perhaps asking the question on
http://sandaysoft.com/forum/index.php may get you a better answer. Sorry for my incomplete or incorrect initial reply
.
