# 透過 指派 AWS Backup 資源 CloudFormation
<a name="assigning-resources-cfn"></a>

此end-to-end CloudFormation 範本會建立資源指派、備份計畫和目的地備份文件庫：
+ 名為 *CloudFormationTestBackupVault* 的備份文件庫。
+ 名為 *CloudFormationTestBackupPlan* 的備份計畫。此計畫會執行兩條備份規則，這兩條規則每天都會在 UTC 時間中午 12 點執行備份，且備份保留期為 210 天。
+ 選取的資源名為 *BackupSelectionName*.
+ 
  + 資源指派會備份下列資源：
    + 任何以鍵值對 `backupplan:dsi-sandbox-daily` 標記的資源。
    + 以值 `prod` 或開頭為 `prod/` 的多個值標記的任何資源。
  + 資源指派不會備份下列資源：
    + 任何 RDS、Aurora、Neptune 或 DocumentDB 叢集。
    + 以值 `test` 或開頭為 `test/` 的多個值標記的任何資源。
