Those aren’t “Folders,” they’re Shares. :)
I don’t remember having two different Timemachine shares, but I am not sure.
I would recommend you download the User Manual and get familiar with the functions, as well as the different Mobile Access options, before comitting yourself to a specific path.
I would also recommend you create your OWN share, make sure the access rights are secure, and use that for your workflow.
Public: Is visible and changable by anyone who can access your drive through any means.
TimeMachine: That’s for Apple backups.
Smartware: That’s for use with WD Smartware backup software.
If your photographs are important to you, then you also need to spend time thinking about how you’re going to back up all of your stuff in case of failure or disaster.
