Shared File Services

On This Page

Shared File Services (SFS) provide file storage which enables sharing of files between groups of users and computers.

  • Support either the CIFS or NFS (v3) protocols.
  • Off-site Disaster Recovery copy of the data maintained for protection against an Ithaca campus disaster. (No extra fee.)
  • Optional snapshots of the data within the share itself (usable for restoring individual files).
  • Replication of the data across two physical sites on campus. (Requires extra fee.)

Colleges, units, departments, and individuals can order shares of varying sizes. 

An Organizational Unit (OU) Primary Admin must approve requests for new shares (login required).

Shares are centrally provided, monitored, and have an offsite disaster recovery (DR) copy.

The following protocols and operating systems are supported.

Windows X
Macintosh X
Unix X

For research data or data that requires archival services, you may also want to consider the storage services from the Center for Advanced Computing.

Terms and Conditions

Fees are billed monthly to your Kuali Account as listed under Fees and Billing.

Computers accessing Shared File Services must comply with the Technical Requirements.

Computers accessing shares configured for high-risk (formerly “confidential”) data must be configured and managed in compliance with Policy 5.10 Information Security by the technical support provider.

What to use a share for? See the Appropriate Uses for Shares page.

Service Details:

Best For:

  • University (mission data) that needs to be stored in a secure, central location. 
  • Files you want to share within your department or with other departments at the University.


  • Low velocity data. Less than a 20% daily change rate. Examples: Microsoft Office documents; small databases (with a very small number of users); disk-image storage (ISO, DMG); files without excessive updates/downloads.
  • If daily change rate is higher than 20%, but data does not require DR-backups, Shared File Services may still be appropriate.  Examples: Data composed of temporary files from a data conversion process (no possible DR restoration) or duplicate data files whose master copy is elsewhere.
