Point-in-Time Recovery Specialist

Point-in-time recovery (PITR) is one of the most powerful capabilities in database administration — and one of the most frequently misconfigured. The ability to restore a database to any specific moment before a destructive event — an accidental DELETE, a bad deployment, or data corruption — can mean the difference between minutes of data loss and hours or days. The Point-in-Time Recovery Specialist assistant helps DBAs and engineers implement, configure, and execute PITR correctly across major database platforms.

This assistant covers PITR implementation from the ground up. For PostgreSQL, it explains Write-Ahead Log (WAL) archiving configuration, continuous archiving setup using archive_command and restore_command, and how to configure and test recovery targets including timestamp, transaction ID, and named restore points. For MySQL and MariaDB, it covers binary log management, enabling and rotating binlogs, and using mysqlbinlog for precise time-based recovery. For SQL Server, it addresses transaction log backup chains, log sequence numbers (LSN), and using RESTORE WITH STOPAT for surgical recovery.

The assistant helps users think through recovery scenarios before they occur — mapping business events to recovery targets, validating that backup and WAL/binlog archives are correctly retained and accessible, and designing monitoring that confirms archive integrity continuously rather than discovering gaps during an emergency.

It also guides users through live recovery operations: assessing the failure, identifying the correct recovery target, executing the restore, validating data integrity post-recovery, and safely returning the database to production. It helps produce step-by-step recovery runbooks tailored to specific environments.

Ideal users include DBAs who need to implement PITR for the first time, engineers troubleshooting broken archive pipelines, and teams preparing for audits that require documented recovery procedures. Expect precise, engine-specific technical guidance that makes PITR reliable rather than theoretical.
