This step-by-step guide will show you how to log into Globus and use it to transfer files reliably and securely. You will become familiar with basic Globus concepts and interfaces, and begin to experience how Globus can help you spend more time on your research and less time on data management.
1. Log in with an existing identity
Visit www.globus.org and click "Login" at the top of the page. On the Globus login page, choose an organization you’re already registered with, such as your school or your employer. (Try typing a few letters of your organization’s name to narrow the list.) When you find it, click "Continue."" If you can’t find your organization in the list, you can use Google, ORCID, or GlobusID, all three of which allow you to create new accounts if you don’t already have one.
You’ll be redirected to your organization’s login page. Use your credentials for that organization to login. (The example below shows the University of Michigan’s login page.)
Some organizations will ask for your permission to release your account information to Globus.
Once you’ve logged in with your organization, Globus will ask if you’d like to link to an existing account. If this is your first time logging in to Globus, click "Continue." If you’ve already used another account with Globus, you can choose "Link to an existing account."
You may be prompted to provide additional information such as your organization and whether or not Globus will be used for commercial purposes. Complete the form and click "Continue."
Finally, you need to give Globus permission to use your identity to access information and perform actions (like file transfers) on your behalf.
2. The File Manager
After you’ve signed up and logged in to Globus, you’ll begin at the File Manager.
The first time you use the File Manager, all fields will be blank.
A collection is a named location containing data you can access with Globus. Collections can be hosted on many different kinds of systems, including campus storage, HPC clusters, laptops, Amazon S3 buckets, Google Drive, and scientific instruments. When you use Globus, you don’t need to know a physical location or details about storage. You only need a collection name. A collection allows authorized Globus users to browse and transfer files. Collections can also be used for sharing data with others, for data publication, and for enabling discovery by other Globus users. Globus Connect is used to host collections.
3. Access a collection
Click in the Collection field at the top of the File Manager page and type "globus tutorial end". Globus will list collections with matching names. The collections
Globus Tutorial Endpoint 1 and
Globus Tutorial Endpoint 2 are collections administered by the Globus team for demonstration purposes and are accessible to all Globus users without further authentication.
Globus Tutorial Endpoint 1. Globus will connect to the collection and display the default directory,
/~/. (It will be empty.) Click the "Path" field and change it to
/share/godata/. Globus will show the files in the new path: three small text files.
4. Request a file transfer
Transfer or Sync to… in the command panel on the right side of the page. A new collection panel will open, with a "Transfer or Sync to" field at the top of the panel.
Globus Tutorial Endpoint 2 collection and connect to it as you did with the
Globus Tutorial Endpoint 1 above. The default directory,
/~/ will again be empty. Your goal is to transfer the sample files here. Click on the left collection,
Globus Tutorial Endpoint 1, and select all three files. The
Start> button at the bottom of the panel will activate.
Between the two Start buttons at the bottom of the page, the
Transfer & Sync Options tab provides access to several options. By default, Globus verifies file integrity after transfer using checksums. Click the information icons for explanations of the other transfer settings. Globus gives you powerful control over the behavior of the transfer with a simple mouse click. Change the transfer settings if you’d like. You may also enter a label for the transfer, but this isn’t required.
Start> button to transfer the selected files to the collection in the right panel. Globus will display a green notification panel—confirming that the transfer request was submitted—and add a badge to the Activity item in the command menu on the left of the page.
After you request a file transfer, Globus takes over and does the work on your behalf. You can navigate away from the File Manager, 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 collection downtime.
The Globus service routinely achieves high availability, providing nearly uninterrupted oversight of data transfers taking place on much less reliable networks and collection hosts. When a problem is encountered part-way through the 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 don’t complete within the authentication expiration period of a collection (which is controlled by the collection administrator). If your credentials expire before the transfer completes, Globus will notify you to re-authenticate on the collection, after which Globus will continue the transfer from where it was paused.
These wide-ranging capabilities make data transfer with Globus truly "fire-and-forget."
5. Confirm transfer completion
Only three small files were transferred in our simple example, so the transfer will complete quickly. Click
Activity in the command menu on the left of the page to go to the Activity page. On the Activity page, click the arrow icon on the right to view details about the transfer. You will also receive an email with the transfer details.
File Manager in the command menu on the left of the Activity page to return to the File Manager. The collections you were viewing before will reappear. You may notice that the transferred files are not listed in the right panel with the
Globus Tutorial Endpoint 2 collection and the
/~/ path, even though the transfer has completed. Click the refresh icon (circular arrows) at the top of the collection panel to see the updated contents.
Globus Tutorial Endpoint 1and
Globus Tutorial Endpoint 2demonstration collections, so if you return later these files may be gone.
6. Move beyond getting started
At this point you’ve mastered the basic Globus data transfer capabilities by copying files between two collections accessible to all Globus users. You know how to specify additional transfer options (such as encryption), understand how Globus manages the transfer on your behalf, and are familiar with Activity notices that let you find out about transfer task progress. You are well on your way to letting Globus simplify your research data management.
Follow the next steps suggested here or explore globus.org on your own to understand and experience more of what Globus has to offer.
Before proceeding, there’s one final concept you should learn: the endpoint.
An endpoint is a server that hosts collections. If you want to be able to access, share, transfer, or manage data using Globus, the first step is to create an endpoint on the system where the data is (or will be) stored.
Globus Connect is used to create endpoints. An endpoint can be a laptop, a personal desktop system, a laboratory server, a campus data storage service, a cloud service, or an HPC cluster. As explained below, it’s easy to set up your own Globus endpoint on a laptop or other personal system using Globus Connect Personal. Administrators of shared services (like campus storage servers) can set up multi-user endpoints using Globus Connect Server. You can use endpoints set up by others as long as you’re authorized by the endpoint administrator or by a collection manager.
