ops(#35): database backup & restore scripts + DR guide - #61
Merged
Conversation
- scripts/backup.sh: timestamped, compressed pg_dump (custom format) with retention pruning; scripts/restore.sh: pg_restore with --clean --if-exists. Both wrap the standard PG client tools and validate DATABASE_URL / tool presence. - make backup target; 'Backups & disaster recovery' section in the deployment guide (nightly cron, Docker Compose variant, restore drill, off-host reminder). - Backup+restore flow validated end-to-end against a real Postgres. All state is in Postgres (the binary is stateless), so a DB dump is a full backup.

Closes #35 — the main ops gap for a self-hosted deployment.
Since the app is stateless (templates/assets embedded in the binary) and all state lives in PostgreSQL, a database dump is a full backup.
