I want to learn and explore SolidWorks PDM. I got PDM Standard with my SW Professional licence. I have two questions:

1. Is PDM useful for single user?

2. At the moment I am using Dropbox for my cloud storage - very important for me to have cloud storage/backup as I don't want to rely on my local storage device just in case if something goes wrong. And I don't have money for a server. What cloud storage platform works best with PDM?

Thanks in advance
