Retention should follow business risk
Not every system needs the same retention period. Financial systems, customer data, and production databases may require longer retention periods than caches, temporary files, or test environments.
Define retention policies by data type, business requirement, and potential impact. This avoids unnecessary costs and gaps that might otherwise become apparent only during an incident.
RPO and RTO make requirements concrete
RPO defines the maximum acceptable data loss. RTO defines how quickly a service must be restored. Without these objectives, backup can become an isolated technical feature that is disconnected from business priorities.
Set these objectives for each system. A public customer portal and an internal archive rarely have the same requirements.
Test recovery before you need it
A recovery test confirms that data, permissions, documentation, and responsibilities work together. A successful backup job alone is not enough.
Schedule regular recovery tests and document the results. This turns backup into a proven recovery process, rather than simply storing copies.
