To design a disaster recovery strategy, define RPO/RTO tiers and implement continuous log archiving for point-in-time-recovery. This framework structures your data recovery plan to meet specific business continuity objectives and validate restore times.

The 3-2-1 backup layout uses immutable storage to protect data against ransomware and accidental deletion. This architecture maintains multiple copies across different media, ensuring at least one offline backup remains unalterable during an attack.

Point-in-time-recovery for stateful datastores like PostgreSQL and MongoDB requires continuous log archiving. This process captures granular database changes, allowing you to restore data to a specific moment before data loss or corruption occurs.

Yes, you can automate restore drills to validate database backup functionality. Automating these recovery tests ensures your backups are functional and actively meet your defined recovery time objectives during a real failure.

Configuring cross-region failover and split-brain fencing involves designing resilience architectures for stateful datastores. This setup prevents simultaneous primary nodes from causing data corruption during regional outages.

You need immutable retention for database backups when protecting against ransomware and accidental deletion. This approach secures continuous log archives, ensuring backup data cannot be modified or deleted before the retention period expires.
