File and Data Storage: AFS

AFS (Andrew File System) is a distributed, networked file system that enables efficient file sharing between clients and servers. AFS files are accessible via the Web or through file transfer programs such as OpenAFS or Fetch (Macintosh) and SecureFX (Windows).

Currently all users with a full-service SUNet ID are granted 5 GB of AFS file space. Additional disk space is available by request for faculty-sponsored research including dissertations.

Features and benefits

  • File sharing —  easily and securely share documents and files over the network with colleagues, workgroups, and even other institutions.
  • File backup and restore —  all data is backed up nightly. Backups are kept for 30 days.
  • File access — easily and securely access your files from other computers.
  • File permissions —  use AFS file permissions to provide access to individuals or groups.
  • Websites — store and serve web pages directly and securely.
  • File security —  files are protected by the Kerberos authentication system.
  • Mobile access — a mobile client is available for the iPhone and iPad. The iYFS app is available from the iTunes store for purchase.
