# Assign AWS Backup resources through CloudFormation
<a name="assigning-resources-cfn"></a>

This end-to-end CloudFormation template creates a resource assignment, a backup plan, and a destination backup vault:
+ 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/`.
