使用 Azure Resource Graph (ARG) 來查詢您的備份

  • 發行項

您可以使用 Azure Resource Graph (ARG) 來查詢 Azure 資源的備份資訊，而不需額外付費。 ARG 是一項 Azure 服務，其設計目的是要延伸 Azure 資源管理。 它的目標是提供有效率的資源探索，讓您能夠在一組指定的訂用帳戶中大規模查詢。 以下是使用 ARG 來查詢您的備份中繼資料的主要優點：

  • 能夠根據資源屬性，使用複雜篩選、群組和排序來大規模查詢資源。
  • 能夠取得備份即時資訊，包括進行中的備份工作。
  • 能夠聯結備份相關資料與相關 Azure 資源 (例如 Azure 虛擬機器和儲存體帳戶) 的實用資訊。

開始使用

若要開始使用 ARG 來查詢您的備份，請遵循下列步驟：

  1. 在 Azure 入口網站中，搜尋 Resource Graph Explorer。 選取相同的項目，以重新導向至 ARG 查詢編輯器。

    Search Azure Resource Group

    左窗格會顯示可供查詢的所有資料表 (和其相關聯結構描述)。

    • RecoveryServicesResources 資料表包含大部分的備份相關記錄，例如工作詳細資料、備份執行個體詳細資料。 依此類推。
    • Resources 資料表包含所有最上層 Azure 資源的資訊，例如復原服務保存庫、Azure 虛擬機器、儲存體帳戶等。

    Available tables and associated schemas for query

  2. 若要探索所有這些資料表中的資料，請在查詢編輯器中撰寫 Kusto 查詢，然後按一下 [執行查詢]。

    您可以從 Resource Graph Explorer 將這些查詢的輸出下載為 CSV。 您也可以使用 ARG 所支援的任何自動用戶端 (例如 PowerShell、CLI 或 SDK)，在自訂自動化中使用這些查詢。 您也可以使用 ARG 作為資料來源，在 Azure 入口網站中建立自訂活頁簿。

注意

  • 最多有 14 天的備份/還原工作可用於 ARG 以進行查詢。 如果您想要查詢歷程記錄，則建議您使用 Azure 監視器記錄。
  • ARG 可讓您查詢您具有適當 RBAC 權限的資源。

範例查詢

下列一些範例 ARG 查詢是針對您可以在自訂儀表板和自動化中使用的備份資料。
