====== RDS Automated Backups ======

**What it is:** Managed backups for RDS that allow point-in-time recovery within a retention window.

**What it’s for:**
  * Restore the DB to a specific time (within retention).
  * Reduce operational overhead for backups.

**Key ideas:**
  * Includes:
    * Daily snapshots
    * Transaction logs
  * Retention period can be configured (within allowed limits by engine/service).

**Exam cues:**
  * “restore DB to 2 hours ago” → automated backups + point-in-time restore.

**Hard words:**
  * *retention* /rɪˈtenʃn/: thời gian lưu giữ
  * *transaction log* /trænˈzækʃn lɔːɡ/: log giao dịch
  * *point-in-time recovery* /ˌpɔɪnt ɪn ˈtaɪm rɪˈkʌvəri/: khôi phục theo thời điểm
