Should I shovel my deck and try to keep it clear of snow?

I have a deck that is probably 15 or a bit more years old. I’m sure it has been oiled and cared for, but when we moved in last year, it needed it again. It didn’t get done and now it is snowing. Is it better for the wood if I try to keep it clear of snow or should I just let the snow build up? My instinct tells me I should keep it as dry as possible and keep shovelling and sweeping away the snow. The temperature has been between freezing and melting, so I know it is wet under that snow mess. Any advice?
