Point-in-time recovery (PITR) in PostgreSQL uses WAL archiving to restore your database to a specific moment. You configure WAL archiving with pg_basebackup to capture physical changes, enabling recovery to any desired timestamp before a corruption incident occurred.

Use pg_dump for logical backups when you need flexibility and selective data restoration. Use pg_basebackup for physical backups when you require faster recovery times and point-in-time recovery capabilities, as it creates a complete binary copy of the database cluster.

Yes, you can execute a full logical backup of a specific PostgreSQL database using pg_dump. The process supports custom formats, allowing you to create a comprehensive backup file of your chosen database for reliable data restoration.

Yes, this PostgreSQL backup and recovery approach supports PostgreSQL 13 and later versions. It manages backup strategies using pg_dump, pg_basebackup, WAL archiving, and PITR for environments running PostgreSQL 13+.

The best way to design a PostgreSQL backup strategy is to choose between logical and physical backups based on your Recovery Point Objective (RPO) and Recovery Time Objective (RTO), combining pg_dump for logical snapshots with WAL archiving for continuous physical protection.

You restore a PostgreSQL database to a pre-corruption state by utilizing point-in-time recovery (PITR) with WAL archives. This allows you to specify the exact moment before the critical incident occurred, minimizing data loss and ensuring business continuity.
