使用 Azure CLI 將 Azure Blob 還原至時間點
本文描述如何使用 Azure 備份，將 Blob 還原至任何時間點。
重要
透過 CLI 的 Azure Blob 備份與還原支援目前處於預覽階段，而在 Az 2.15.0 版和更新版本中會以延伸模組的形式提供。 該延伸模組將會在您執行 az dataprotection 命令時自動安裝。 深入了解擴充功能。
重要
使用 Azure 備份還原 Azure Blob 之前，請參閱重點。
在本文中，您將學會如何：
將 Azure Blob 還原至時間點
追蹤還原作業狀態
我們將會參考範例中，資源群組 testBkpVaultRG 下現有的備份保存庫 TestBkpVault。
在儲存體帳戶內還原 Azure Blob
擷取有效的還原時間範圍
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"
[
{

"extendedLocation": null,
"id": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx/resourceGroups/testBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/TestBkpVault/backupInstances/CLITestSA-CLITestSA-c3a2a98c-def8-44db-bd1d-ff6bc86ed036",

]
識別出執行個體之後，請使用 az dataprotection restorable-time-range find 命令擷取相關復原範圍。
az dataprotection restorable-time-range find --start-time 2021-05-30T00:00:00 --end-time 2021-05-31T00:00:00 --source-data-store-type OperationalStore -g testBkpVaultRG --vault-name TestBkpVault --backup-instances CLITestSA-CLITestSA-c3a2a98c-def8-44db-bd1d-ff6bc86ed036

準備還原要求
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
使用此選項時，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
{
"object_type": "AzureBackupRecoveryTimeBasedRestoreRequest",

"resource_uri": ""
},
"object_type": "RestoreTargetInfo",

"restore_location": "southeastasia"
},
"source_data_store_type": "OperationalStore"
}
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 > restore.json
還原所選容器
使用此選項時，您可以瀏覽並選取要還原的容器，但最多 10 個。 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
{

}

使用前置詞相符項目還原容器
此選項可讓您使用前置詞相符項目還原一部分 Blob。 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
追蹤工作
使用 az dataprotection job list 命令來追蹤所有作業。 您可以列出所有作業，並擷取特定的作業詳細資料。
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
