MY Cloud PR4100 - Installing a Dropbox into the NAS


I have My Cloud PR4100. I want to install a dropbox in there. I want to synchronize my cloud PR4100’s data to Dropbox. I would like to know-how this process works?. I want all my cloud PR4100’s data to synchronize with the Dropbox.

Please guide me that how this process works and also is it safe to install the apps like Dropbox into the NAS?

If I install the Dropbox on NAS. Does it make changes or modifications to any existing data ?

Thank you.
