Snapshot Pro and Doubled Snapshots

Hello,

So, this may be an easy answer. I have snapshot pro installed and backing up various sites. They're not updated hourly, maybe bi monthly so have them set up to back up twice a month. I have the snapshots going to AWS, however, I noticed they're also on my web server as well. Is this what's suppose to happen? Example below.

image 1 is AWS

image 2 is on my web server

Can y'all explain? Thank you.
