Snapshot not copying /wp-uploads under multisite installation

Hello: I am using snapshot to make a backup of all of my multisite installations and send it to my google drive. Everything looks to be working well (I have it scheduled to do the backup weekly) other than the fact that the wp-uploads folders are not being zipped and copied.

I've looked through the settings and I think I have it installed and configured correctly.

Is there something I'm missing?

Thank you,
