[galaxy-dev] Data upload from a server

Dear Galaxy developers, I have installed a Galaxy local instance on our university's server and I am going to use it to analyze data also uploaded on the same server. Nevertheless the access to the server (and the data) is limited only to those involved with the project so making public urls for them is not an option. Downloading the data to my pc is also not an option as its volume is much greater than my hard drive. Is there another way for Galaxy to access those data? Thank you, Efthymios Ladoukakis
