Research Computing has several nodes dedicated to GridFTP file transfer for moving large amounts of data. This protocol addresses deficiencies in secure copy requests: the necessity to monitor large data transfers, the inability to resume failed transfers, and the requisite skill in tuning transfers between high performance computing centers.

Globus Online and GridFTP

Globus Connect is a web client and interface to and from GridFTP servers. RC's GridFTP servers support both the Globus Connect web environment and basic GridFTP via the command line. https://www.globus.org

Other Options

OIT also offers a file transfer service with a web interface which provides a good way to transfer files to collaborators. Files are uploaded to a server and a link to download the file can be emailed to an on, or off-campus, user: http://oit.colorado.edu/safe-transfer
