ITS backs up to tape data on all servers it manages on a daily basis. The backup tapes are retained for a period of three weeks. This is to insure that ITS will be able to restore services running on the servers with minimal loss of information in the event of a disaster. A file that is stored on any ITS server will remain there indefinitely, provided it is not deleted by a user or removed when a user account is closed. If a user deletes a file, either purposely or accidentally, the file can be recovered, in most cases*, from backup tapes if a request for recovery is made 21 days or less after the file is deleted.
This tape retention policy was established with the assistance of the Office of the President, Office of the Provost, and University Counsel. It was designed to protect institutional data while complying with national and state laws and mandates pertaining to e-discovery, data retention, and file retention.
- Back up to tape occurs during the evening and early morning hours during the week. A file created and saved during the day and deleted before being backed up to tape cannot be recovered.
