AFS (Andrew File System) is a distributed file system that enables cooperating hosts (clients and servers) to efficiently share file system resources across local and wide area networks. At Stanford, AFS is easily accessed via the Web and serves as the campus-wide file system. AFS is distributed among eleven servers and provides two terabytes of usable disk space, which is backed up nightly. This stable, distributed system is where the University's main web site and linked files are hosted. It supports storing public data on “AFS at Stanford” or restricted or prohibited data on “Secure AFS at Stanford”.
Backup and Storage
All full-service SUNet ID account holders receive a base amount of disk storage. Services that support university requirements for data encryption of laptop and desktop machines, and a variety of for-fee, encrypted backup and storage solutions, are also available.
A variety of file and data backup solutions are available for desktop computers and servers. AFS is backed up daily, free-of-charge. Backup for other services is by subscription. Charges apply.
See Disk-Based Replication.
Data backup and recovery services (BaRS) for desktop machines. Your local IT support staff or a CRC consultant (for a fee) will install and configure the client software on your computer. Once configured, the software will automatically back up your system at a specified time each workday. If you accidentally overwrite or delete a file, you can recover it yourself using the client software. File recovery is available 24 hours a day, seven days a week.
CrashPlan PROe is a centrally-managed, automatic backup solution for desktops and laptops. CrashPlan PROe is simple to use, highly efficient, and very secure. It allows you to take control of your backups, accessing your data anytime via mobile device, web browser, or desktop client.
Custom storage can be set up for high-performance computing and large research data files. University IT will work with clients, vendors, and other Stanford IT organizations to create and/or coordinate the fastest, most secure, and most cost-effective solutions for emerging technology solutions.
Disk Based Replication uses an active storage disk system to back up and recover files.
Stanford provides document management and collaboration through a partnership with box. com. Box is an easy-to-use platform that is integrated into Stanford's infrastructure.
File Storage provides standard ways to share files across intranets and the Internet. By using a remote file-access protocol that is compatible with the way applications already share data on local disks and network file servers, this service enables collaboration on the Internet.
The Media Storage service fills the needs of a post-production video editing workflow. The service is a complete shared-storage solution that supports collaboration across Linux, Windows, and Mac OS X operating systems while supporting the broadest range of applications.
Shared AFS file storage space for non-public data.
Secure File Storage provides a method of transmitting and storing Moderate and High Risk Data. Individual and group accounts are available to faculty and staff. Anyone using the Secure File Storage service must have Stanford Whole Disk Encryption (SWDE) installed and encrypt their laptop or desktop computer, and must use the Stanford Virtual Private Network (VPN) or Stanford Network Access Control (SUNAC) while transmitting files.
Server Disk Storage is a set of offerings designed for server-class computers. The service balances performance and reliability with cost.
Data storage services that meet Stanford’s needs at all levels — individual, departmental, and institution-wide (enterprise). Solutions range from high throughput and highly-available storage for production databases, to low-cost storage for web content, text files, images, computer programs, and other shared or archived data.
