For PostgreSQL administrators, DBAs, SREs, and platform teams, understanding how backup data moves through a system is just as important as knowing when a backup completed successfully. Questions about repository layout, WAL handling, metadata, integrity, and recovery usually surface when troubleshooting, validating a backup strategy, or preparing for recovery.
