After you initiate a data transfer through the Globus interface, UConn's Globus node takes over and does the work on your behalf. You can navigate away from the Globus web page, close the browser window, and even logout. Globus will optimize the transfer for performance, monitor the transfer for completion and correctness, and recover from network errors and endpoint resource downtime. The Globus service is highly reliable, providing nearly uninterrupted oversight of data transfers. If a problem is encountered part-way through a transfer, Globus resumes from the point of failure and does not retransmit all of the data specified in the original request. Globus can handle extremely large data transfers, even those that do not complete within the authentication expiration period of an endpoint. If your credentials expire before a transfer completes, Globus will notify you to re-authenticate on the endpoint so that it can continue the transfer. These wide-ranging capabilities make data transfer with Globus truly "fire and forget".
