使用 Azure CLI 來還原 Azure Blob

  • 發行項

本文說明如何使用 Azure 備份還原 blob。

您可以透過 Azure CLI，使用操作備份和 Azure Blob 的保存庫備份，將 Azure Blob 還原至時間點。 在這裡，我們會在範例中使用資源群組 testBkpVaultRG 下現有的備份保存庫 TestBkpVault。

重要

使用 Azure 備份還原 Azure Blob 之前，請參閱重點。

擷取詳細資料以還原 Blob 備份

若要還原 Blob 備份，您必須 *擷取操作備份的有效時間範圍，並擷取保存庫備份的恢復點清單。

選擇備份階層：

因為 Blob 備份作業是連續的，所以沒有不同的還原點。 所以我們需要擷取有效的時間範圍，以將 Blob 還原至任何時間點。 在此範例中，讓我們檢查過去 30 天內的有效還原時間範圍。

首先，我們需要擷取相關備份執行個體識別碼。 使用 az dataprotection backup-instance list 命令列出保存庫內的所有備份執行個體，然後使用 az dataprotection backup-instance show 命令擷取相關執行個體。 或者，若為大規模的情況，可以使用 az dataprotection backup-instance list-from-resourcegraph 命令列出保存庫與訂閱之間的備份執行個體。

az dataprotection backup-instance list-from-resourcegraph --datasource-type AzureBlob --datasource-id "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx/resourcegroups/blobrg/providers/Microsoft.Storage/storageAccounts/CLITestSA"

準備還原要求

選擇備份階層：

您修正還原時間點後，就有多個選項可供還原。

將所有 Blob 還原至某個時間點

您可以還原儲存體帳戶中的所有區塊 Blob，方法是將 Blob 回復至選取的時間點。 包含大量資料或見證高度變換的儲存體帳戶所需的還原時間可能較長。 若要還原所有區塊 Blob，請使用 az dataprotection backup-instance restore initialize-for-data-recovery 命令。 還原位置和目標資源識別碼將會與受保護的儲存體帳戶相同。

az dataprotection backup-instance restore initialize-for-data-recovery --datasource-type AzureBlob --restore-location southeastasia --source-datastore OperationalStore --target-resource-id "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx/resourcegroups/blobrg/providers/Microsoft.Storage/storageAccounts/CLITestSA" --point-in-time 2021-06-02T18:53:44.4465407Z

  },
  "source_data_store_type": "OperationalStore"

還原所選容器

您可以瀏覽並選取最多 10 個要還原的容器。 若要還原所選取的容器，請使用 az dataprotection backup-instance restore initialize-for-item-recovery 命令。

az dataprotection backup-instance restore initialize-for-item-recovery --datasource-type AzureBlob --restore-location southeastasia --source-datastore OperationalStore --backup-instance-id "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx/resourceGroups/testBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/TestBkpVault/backupInstances/CLITestSA-CLITestSA-c3a2a98c-def8-44db-bd1d-ff6bc86ed036" --point-in-time 2021-06-02T18:53:44.4465407Z --container-list container1 container2

{
  "object_type": "AzureBackupRecoveryTimeBasedRestoreRequest",

        "object_type": "RangeBasedItemLevelRestoreCriteria"
      }
    ],
    "restore_location": "southeastasia"
  },
  "source_data_store_type": "OperationalStore"
}

az dataprotection backup-instance restore initialize-for-item-recovery --datasource-type AzureBlob --restore-location southeastasia --source-datastore OperationalStore --backup-instance-id "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx/resourceGroups/testBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/TestBkpVault/backupInstances/CLITestSA-CLITestSA-c3a2a98c-def8-44db-bd1d-ff6bc86ed036" --point-in-time 2021-06-02T18:53:44.4465407Z --container-list container1 container2 > restore.json

使用前置詞相符項目還原容器

您可以使用前置詞相符項目還原 Blob 的子集。 您可以在單一容器內或跨多個容器指定最多 10 個字典式的 Blob 範圍，讓這些 Blob 回復到過去的指定時間點狀態。 請牢記以下幾點：

  • 您可以使用正斜線 (/) 在 Blob 前置詞中劃定容器名稱。
  • 指定範圍的開頭包含在內，但指定的範圍為獨佔。

深入了解如何使用前置詞還原 Blob 範圍。

若要還原所選取的容器，請使用 az dataprotection backup-instance restore initialize-for-item-recovery 命令。

az dataprotection backup-instance restore initialize-for-item-recovery --datasource-type AzureBlob --restore-location southeastasia --source-datastore OperationalStore --backup-instance-id "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx/resourceGroups/testBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/TestBkpVault/backupInstances/CLITestSA-CLITestSA-c3a2a98c-def8-44db-bd1d-ff6bc86ed036" --point-in-time 2021-06-02T18:53:44.4465407Z --from-prefix-pattern container1/text1 container2/text4 --to-prefix-pattern container1/text4 container2/text41

觸發還原

使用 az dataprotection backup-instance restore trigger 命令，以上述備妥的要求來觸發還原。

az dataprotection backup-instance restore trigger -g testBkpVaultRG --vault-name TestBkpVault --backup-instance-name CLITestSA-CLITestSA-c3a2a98c-def8-44db-bd1d-ff6bc86ed036 --restore-request-object restore.json

追蹤作業

您可以使用 az dataprotection job list 命令來追蹤所有作業。 您可以列出所有工作，並擷取特定的工作詳細資料。

您也可以使用 Az.ResourceGraph，追蹤所有備份保存庫中的所有作業。 使用 az dataprotection job list-from-resourcegraph 命令，取得可跨任何備份保存庫的相關工作。

az dataprotection job list-from-resourcegraph --datasource-type AzureBlob --operation Restore
