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
