Backup and Recovery | Agent Skills Atlas

About this skill

PostgreSQL's backup + point-in-time recovery — pgbasebackup + WAL archiving (archivecommand / archivelibrary) + restorecommand + pgwalreplay targets + the pgbackupstart/stop API + pgreceivewal. Covers src/backend/backup/ (basebackup server code) + src/backend/postmaster/pgarch.c (archiver aux process) + src/backend/access/transam/xlogrecovery.c (recovery driver). Loads when the user asks about how base backups work, WAL archiving vs streaming replication, PITR targets (recoverytarget), pgbackupstart/pgbackupstop low-level API, .backup files, restorecommand semantics, or incremental backup (PG 17+ with WALSUMMARIZED). Skip when the ask is about pgdump (logical dump — different tool) or about physical replication streaming (physical-replication — related but sibling).

Original description

PostgreSQL's backup + point-in-time recovery — `pg_basebackup` + WAL archiving (archive_command / archive_library) + `restore_command` + `pg_wal_replay_*` targets + the pg_backup_start/stop API + `pg_receivewal`. Covers `src/backend/backup/` (basebackup server code) + `src/backend/postmaster/pgarch.c` (archiver aux process) + `src/backend/access/transam/xlogrecovery.c` (recovery driver). Loads when the user asks about how base backups work, WAL archiving vs streaming replication, PITR targets (`recovery_target_*`), `pg_backup_start`/`pg_backup_stop` low-level API, `.backup` files, restore_command semantics, or incremental backup (PG 17+ with `WAL_SUMMARIZED`). Skip when the ask is about `pg_dump` (logical dump — different tool) or about physical replication streaming (`physical-replication` — related but sibling).
