- Mei Sun
Analytics
ITIL Standard
Assumptions
•Data backup and restore requests are fulfilled by the City’s TSD
•Data backup refers to backups at the database or OS level
•Data backup and restore requests must follow the request management process
•Data backup:
•Automated process based on a set schedule
•Application admins can request on-demand backups during new changes, system upgrades, and configuration changes
•Data restore:
•Can be used to baseline lower environments
•Only application admins can request data restoration due to loss of data, infrastructure failures or backouts of new changes
Goal
The primary goal of the data backup and restore process is to protect valuable data by making periodic backups to a separate location. Backups can be used during disaster recovery to restore the system back to operational state and to minimize downtime.
Objectives
Maintain the data integrity by having backups of data that can be used in the event of data corruption or data loss.
2. Maintain a production copy that can be used in the event of a failed implementation and the need to roll back changes.
3. The ability to use production copy to re-base lower environments.
4. Backups are made on a scheduled basis to insure no loss of data between each backup.
