Cloud-based computer file transfer service for remote stations connected to narrowband Internet

Data transfer is an important task in any scientific activity. Concordia Station in Antarctica does not have a reliable satellite Internet service and the IT facilities are not easy to use for some of the staff. This work describes the implementation of a file transfer system, so simple to allow anyone its use. With this system Concordia staff were able to transmit, easily, digital content to their collaborators in the rest of the world in full autonomy. Since the system is based on a technological infrastructure managed by staff belonging to National Research facilities, storage and confidentiality of data is also kept without having to transfer it to third party companies.
