This policy defines the backup policy for computers within the organization which are expected to have their data backed up. These systems are typically servers but are not necessarily limited to servers. Servers expected to be backed up include the file server, the mail server, and the web server.
This policy is designed to protect data in the organization to be sure it is not lost and can be recovered in the event of an equipment failure, intentional destruction of data, or disaster.
This policy applies to all equipment and data owned and operated by the organization.
- Backup - The saving of files onto magnetic tape or other offline mass storage media for the purpose of preventing loss of data in the event of equipment failure or destruction.
- Archive - The saving of old or unused files onto magnetic tape or other offline mass storage media for the purpose of releasing on-line storage room.
- Restore - The process of bringing off line storage data back from the offline media and putting it on an online storage system such as a file server.
