  • A backup vault named CloudFormationTestBackupVault.

  • A backup plan named CloudFormationTestBackupPlan. This plan will run two contains two backup rules, both of which take backups daily at 12 noon UTC and retain them for 210 days.

  • A resource selection named BackupSelectionName.

    • The resource assignment backs up the following resources:

      • Any resource tagged with the key-value pair backupplan:dsi-sandbox-daily.

      • Any resource tagged with the value prod or values beginning with prod/.

    • The resource assignment does not back up the following resources:

      • Any RDS, Aurora, Neptune, or DocumentDB cluster.

      • Any resource tagged with the value test or values beginning with test/.
