The idea is to create an app that would for an example take a standard USB or old laptop. And to turn it into a cloud that is similar to that of Google Drive. The difference would be, that instead of sending the files somewhere else or to the google center - everything is going to be within the home router - placed on the usb. What would be your software recommendations for a start? All help is greatly appreciated.
Options: If possible to make it encrypted or make it an option. Highly customize a specific distribution of open-source linux server just for this use only.
