Replace simple pg_dumpall with pgBackRest PITR backup system. This enables recovery to any second, not just the last daily dump. Configuration: - docker/postgres/postgresql.conf: WAL archiving + performance tuning (shared_buffers=512MB, effective_cache_size=2GB for 16GB Mac Mini) - docker/postgres/pgbackrest.conf: stanza config + retention policy Docker (docker-compose.macmini.yml): - postgres: mount custom config, enable WAL archiving - postgres-backup: new pgBackRest container - Storage: /Volumes/ManaData/backups/pgbackrest - Retention: 4 full + 14 differential (~4 weeks) - Compression: Zstandard (zst) Backup Schedule: - 03:00 daily: Full backup - Every 6h: Differential (changes since last full) - Every hour: Incremental (changes since last backup) - Continuous: WAL archiving (every 60s) Documentation (docs/POSTGRES_BACKUP.md): - Complete restore procedures (full, PITR, single DB) - First-time setup instructions - Monitoring and alerting integration Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
