The usage and quota information for your group and the users in the group are stored in a filed named "disk_usage.txt" in your group's directory (
/attic/<groupname>). You can use either Globus Connect or scp to download it. Your usage and expiration is also shown in the web interface (see below).
Use the web interface
For convenience, a web interface is also provided. Simply go to https://attic.unl.edu and login with your HCC credentials. Using this interface, you can see your quota usage and expiration, manage files, etc. Please note we do not recommend uploading/downloading large files this way. Use one of the other transfer methods above for large datasets.
