Doing More with AFS

To increase security and reduce risk, Stanford is sunsetting its WebAFS service that is used to upload and download files to AFS.

To optimize AFS and make sure it is serving its intended functions, UIT has also taken these actions:

  • UIT no longer automatically provisions new faculty and staff members with AFS user volumes. New faculty or staff who need a personal user volume must submit a Help request.
    • This change does not impact existing AFS directories or the process for adding permissions for new individuals to those existing directories. Your existing space and everything in it remains intact.
    • This change does not impact auto-provisioning of new AFS user volumes for students and postdocs.
  • All user, department, and group AFS volumes must be renewed annually or they will be locked, archived, and permanently deleted as detailed in the AFS Volume Expiration Policy
  • Class volumes are exempt from expiration.

Once you've mastered the basics you'll want to learn more AFS tips, tricks, concepts and commands. This page should help you find practical information about working with AFS, including answers to common questions and problems.

Backup images: recovering your own files

Almost all AFS volumes have a backup image from the night before available. Here's how to find it and use it.

Tokens: your identity to the file system

Since AFS is a networked file system, you must establish your identity not only on your local machine, but also to all the machines in the AFS cell.
