Backup

Production Compose includes a backup profile service.

What it does

• pg_dump of PostgreSQL → gzip on the backup_data volume
• MinIO mirror via mc (image includes both pg_dump and mc)
• Retention: 7 days on-volume (BACKUP_KEEP_DAYS, default 7)
• Interval: BACKUP_INTERVAL_SEC (default 86400)

Enable

Remote deploy already starts backup:

docker compose -f docker-compose.yml -f docker-compose.prod.yml --profile backup up -d backup

One-shot:

BACKUP_ONCE=1 docker compose … run --rm backup

Offsite

Copy /backups (or the named volume) to object storage / another host regularly. Volume retention alone is not disaster recovery.
