Redundancy: Backups: What is backed up and how often?
Options:Option 1: Never backup anything.
Option 2: Backup critical information when you feel concerned about losing it.
Option 3: Backup everything periodically.
Option 4: Create and maintain different backup processes and schedules for different information based on its criticality.
Option 5: Continuously and automatically backup everything all the time.
Basis:Never backup anything.
Some things should not be backed up because they unnecessarily consume space. This includes standard distributions of operating environments where there are many existing backups and a standard regeneration process and other similar collections that are readily recreated. Other things not to backup include data that is for temporary use only, like authentication codes used on specific transactions (e.g., credit card present digits), cookies for systems where there is no desire to retain long-term state information, temporary files such as those used in processing other data, data on kiosk machines in lobby areas, and other content that has little or no utility after its initial use. In the forensics arena, there are also cases where backup is not permitted, for example under court orders relating to making copies of certain content, and in cases where old copies may create confusion or legal issues associated with discovery limited backups or automatic overwrite of backups with newer data may be used.
