Regla 0: backup sin restore probado = no tenés backup.

| Métrica | Significado | Target Educabot |
|---|---|---|
| RPO | Cuánto dato podés perder | 5 min (PITR) |
| RTO | Cuánto tardás en volver | 1h (crítico), 4h (general) |
Definir antes de diseñar. Acordar con producto/legal.
| Capa | Qué | Retention |
|---|---|---|
| Managed snapshots (Cloud SQL) | Snapshot diario + PITR | 7-30d snapshots, 7d WAL |
| pg_dump lógico | Export off-provider a GCS multi-region | 30d daily, 3m weekly, 1y monthly |
| WAL archiving | Continuo a GCS (si RPO <1h) | 7d |
Bucket: versioning + object lock + multi-region + IAM write-only para job.
pg_restore --jobs=4Mismas tres capas que Postgres: backups del proveedor con PITR (binlogs en MySQL, continuous backup en Atlas), una copia lógica fuera del proveedor y restore mensual. En MongoDB sharded, mongodump no es consistente entre shards.

| Escenario | Estrategia | RTO |

| Corrupción por bug | PITR → cutover | 1h |

| Account comprometido | Rebuild desde IaC + backups off-provider | 24-48h |
