Postgres Cluster and Database Backup
摘要
The identification of backup requirements for critical data recovery in the event of an outage or disaster is a collaborative effort involving project managers, business application owners, and database administrators (DBAs). The key aspects in designing backup solutions are determining the amount of data that can be lost in case of a failure or disaster, as well as the time it takes to recover the system to make it operational again. Project managers, business application owners, and DBAs work together to understand the criticality of the data and the impact of downtime. Backups are essential for restoring user data, before database upgrades, for cloning databases on other systems, to set up replicas, and to implement high availability.
