Data Management in the RDMS

Data can be uploaded or downloaded from the RDMS in multiple ways. In the RDMS web interface, you can upload one file at a time as long as it is not bigger than 50 MB, but for multiple files, it is easier to use other applications. This page provides a general overview of the offered solutions. Please refer to the separate Wiki pages that explain the data transfer options in more detail.

Note Only UG members with a personnel number (P-number) or student number (S-number) can log in to the RDMS directly. Please contact us if other UG accounts, for example, functional accounts (F-number), need access.

The RDMS is only accessible from the RUG network; only with an IP-address from the UG can you log in. On UG premises, an Eduroam connection will give you an internal IP-address. On other machines/locations, you can use a VPN connection or the virtual Windows or virtual Linux environment of the UG.

In general, the RDMS is accessible via the following methods and interfaces that allow for data transfer/management.

• RDMS web interface
  Via the RDMS web interface, it is possible to transfer files directly as long as they are not bigger than 50 MB.

• WebDAV
  The WebDAV protocol is a major way to access the RDMS from all of the common OS (Windows, MacOS, Linux). There are multiple clients to use for WebDAV, for example, WinSCP, Cyberduck, or NextCloud. It is also possible to incorporate the RDMS drive directly in the file explorer of your OS.
  The general configuration for WebDAV access to the RDMS uses the following parameters:
  • Username: <username>@rug.nl or <username>@student.rug.nl (equal to your UG mail adress)
  • Server: webdav.data.rug.nl
  • We made separate pages with the instructions about configuring a WebDAV client for Windows, MacOS, and Linux.

• Command-line
  Using the command-line interface is currently only available to Linux users. To log in via the command-line, you need to have iCommands installed and create a profile in your Linux home directory. The more advanced Windows users can install WSL2, a virtualization of the Linux kernel in the Windows OS, and then use it to work via the command-line using iCommands. This option is for advanced Windows users who need to upload huge amounts of data (>100Gb). Please also take a look at the Wiki page on file sizes on the RDMS.
