使用数据保护 REST API 还原 PostgreSQL 数据库

本文介绍如何使用数据保护 REST API，将通过 Azure 备份的 PostgreSQL 数据库还原到 Azure Database for PostgreSQL 服务器。 还可以使用 Azure 门户、 Azure PowerShell 和 Azure CLI 还原 PostgreSQL 数据库。

由于 PostgreSQL 数据库是一个平台即服务（PaaS）数据库，因此不支持替换现有数据库（从中执行备份）来还原 Original-Location 恢复（OLR）选项。 可以从恢复点还原，以在同一 Azure Database for PostgreSQL 服务器或任何其他 PostgreSQL 服务器中创建新数据库。 此选项称为Alternate-Location Recovery (ALR)。 ALR 有助于同时保留源数据库和还原的（新）数据库。

先决条件

本文中的示例指的是资源组TestBkpVault下名为testBkpVaultRG的现有备份保管库。

还原已备份的 PostgreSQL 数据库

设置权限

备份保管库使用托管标识访问其他 Azure 资源。 若要从备份还原，备份保管库的托管标识需要对数据库应还原到的 Azure Database for PostgreSQL 服务器拥有一组权限。

若要在目标 PostgreSQL 服务器上为保管库的系统分配的托管标识分配相关权限，请参阅备份 PostgreSQL 数据库所需的权限。

若要将恢复点作为文件还原到存储帐户，备份保管库的系统分配的托管身份需要具有对目标存储帐户的访问权限。

提取相关恢复点

若要列出备份实例的所有可用恢复点，请使用 列表恢复点 API：

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.DataProtection/backupVaults/{vaultName}/backupInstances/{backupInstanceName}/recoveryPoints?api-version=2021-07-01

例如，此 API 转换为：

GET https://management.azure.com/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/TestBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupInstances/testpostgresql-empdb11-aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e/recoveryPoints?api-version=2021-07-01

对恢复点列表的响应

提交 GET 请求后，它将返回以下响应。 它还返回包含相关详细信息的所有离散恢复点的列表。

名称 类型 说明
200 OK AzureBackupRecoveryPointResourceList 请求已完成。
其他状态代码 CloudError 错误响应描述操作失败的原因。

若要从存档层提取恢复点，请将 type 变量在 recoveryPointDataStoreDetails 中修改为 ArchiveStore。

从前面的列表中选择相关的恢复点，然后准备还原请求。 本文使用上面列表中名为794ead7c7661410da03997d210d469e7的恢复点进行还原。

准备还原请求

PostgreSQL 数据库有各种还原选项。 可将恢复点还原为另一个数据库或还原为文件。 恢复点也可以位于存档层上。

还原为数据库

使用分配权限的目标 PostgreSQL 服务器（如前面详述）构造要创建的新 PostgreSQL 数据库的 Azure 资源管理器 ID。 包括所需的 PostgreSQL 数据库名称。 例如，可以在资源组 emprestored21 中具有不同订阅、名为 targetossserver 的目标 PostgreSQL 服务器下将 PostgreSQL 数据库命名为 targetrg：

"/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx/resourceGroups/targetrg/providers/providers/Microsoft.DBforPostgreSQL/servers/targetossserver/databases/emprestored21"

以下请求正文包含恢复点 ID 和还原目标详细信息：

{
  "restoreRequestObject": {
    "objectType": "AzureBackupRecoveryPointBasedRestoreRequest",
    "sourceDataStoreType": "VaultStore",
    "restoreTargetInfo": {
      "objectType": "restoreTargetInfo",
      "recoveryOption": "FailIfExists",
      "dataSourceInfo": {
        "objectType": "Datasource",
        "resourceID": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/targetrg/providers/Microsoft.DBforPostgreSQL/servers/targetossserver/databases/emprestored21",
        "resourceName": "emprestored21",
        "resourceType": "Microsoft.DBforPostgreSQL/servers/databases",
        "resourceLocation": "westus",
        "resourceUri": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/targetrg/providers/Microsoft.DBforPostgreSQL/servers/targetossserver/databases/emprestored21",
        "datasourceType": "Microsoft.DBforPostgreSQL/servers/databases"
      },
      "dataSourceSetInfo": {
        "objectType": "DatasourceSet",
        "resourceID": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/targetrg/providers/Microsoft.DBforPostgreSQL/servers/targetossserver",
        "resourceName": "targetossserver",
        "resourceType": "Microsoft.DBforPostgreSQL/servers",
        "resourceLocation": "westus",
        "resourceUri": "",
        "datasourceType": "Microsoft.DBforPostgreSQL/servers/databases"
      },
      "datasourceAuthCredentials": {
        "objectType": "SecretStoreBasedAuthCredentials",
        "secretStoreResource": {
          "secretStoreType": "AzureKeyVault",
          "uri": "https://vikottur-test.vault.azure.net/secrets/dbauth3",
          "value": null
        }
      },
      "restoreLocation": "westus"
    },
    "recoveryPointId": "eb006fde78cb47198be5a320fbe45e9b"
  }
}

对于基于存档的恢复点，需要：

  1. 从存档数据存储解除冻结到保管库数据存储。
  2. 修改源数据存储。
  3. 添加其他参数以指定解除冻结优先级。
  4. 指定解除冻结的恢复点应在保管库数据存储中保留的持续时间。

    "rehydration_priority": "Standard",
    "rehydration_retention_duration": "P15D",
  }
}

作为文件还原

如 前面所述，提取存储帐户中分配权限的容器的 URI。 例如，在名为 testcontainerrestore 的存储帐户下，使用名为 testossstorageaccount 的容器，并且该容器隶属于不同的订阅：

"https://testossstorageaccount.blob.core.windows.net/testcontainerrestore"

{
  "objectType": "ValidateRestoreRequestObject",
  "restoreRequestObject": {
    "objectType": "AzureBackupRecoveryPointBasedRestoreRequest",
    "sourceDataStoreType": "VaultStore",
    "restoreTargetInfo": {
      "targetDetails": {
        "url": "https://testossstorageaccount.blob.core.windows.net/testcontainerrestore",
        "filePrefix": "empdb11_postgresql-westus_1628853549768",
        "restoreTargetLocationType": "AzureBlobs"
      },
      "restoreLocation": "westus",
      "recoveryOption": "FailIfExists",
      "objectType": "RestoreFilesTargetInfo"
    },
    "recoveryPointId": "eb006fde78cb47198be5a320fbe45e9b"
  }
}

对于基于存档的恢复点，请修改源数据存储。 添加解冻优先级和解冻恢复点的保留时长（以天为单位）：

{
  "objectType": "ValidateRestoreRequestObject",
  "restoreRequestObject": {
    "objectType": "AzureBackupRecoveryPointBasedRestoreRequest",
    "sourceDataStoreType": "ArchiveStore",
    "restoreTargetInfo": {
      "targetDetails": {
        "url": "https://testossstorageaccount.blob.core.windows.net/testcontainerrestore",
        "filePrefix": "empdb11_postgresql-westus_1628853549768",
        "restoreTargetLocationType": "AzureBlobs"
      },
      "restoreLocation": "westus",
      "recoveryOption": "FailIfExists",
      "objectType": "RestoreFilesTargetInfo"
    },
    "recoveryPointId": "eb006fde78cb47198be5a320fbe45e9b",
    "rehydration_priority": "Standard",
    "rehydration_retention_duration": "P15D",
  }
}

验证还原请求

准备请求正文后，使用 “验证还原 API”对其进行验证。 与验证备份 API 一样，此 API 是 POST 操作。

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.DataProtection/backupVaults/{vaultName}/backupInstances/{backupInstanceName}/validateRestore?api-version=2021-07-01

例如，上述 API 转换为：

POST "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/testBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupInstances/testpostgresql-empdb11-aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e/ValidateRestore?api-version=2021-07-01"

详细了解 此 POST API 的请求正文。

用于验证还原请求的请求正文

在前面的部分中构造了请求正文。 现在，添加对象类型并将其用于触发验证作：

    "recoveryPointId": "eb006fde78cb47198be5a320fbe45e9b",
    "restoreRequestObject": {
      "objectType": "AzureBackupRecoveryPointBasedRestoreRequest",
      "sourceDataStoreType": "VaultStore",
      "restoreTargetInfo": {
        "objectType": "restoreTargetInfo",
        "recoveryOption": "FailIfExists",
        "dataSourceInfo": {
          "objectType": "Datasource",

          "datasourceType": "Microsoft.DBforPostgreSQL/servers/databases"
        },
        "dataSourceSetInfo": {
          "objectType": "DatasourceSet",
          "resourceID": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/targetrg/providers/Microsoft.DBforPostgreSQL/servers/targetossserver",

          "resourceUri": "",
          "datasourceType": "Microsoft.DBforPostgreSQL/servers/databases"
        },
        "datasourceAuthCredentials": {
          "objectType": "SecretStoreBasedAuthCredentials",
          "secretStoreResource": {
            "secretStoreType": "AzureKeyVault",
            "uri": "https://vikottur-test.vault.azure.net/secrets/dbauth3",
            "value": null
          }
        },
        "restoreLocation": "westus"
      }
  }
}

触发还原请求

触发还原请求的操作是 API POST 。 了解有关此操作的更多信息。

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.DataProtection/backupVaults/{vaultName}/backupInstances/{backupInstanceName}/restore?api-version=2021-07-01

例如，此 API 转换为：

POST "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/testBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupInstances/testpostgresql-empdb11-aaaa0a0a-bb1b-cc2c-dd3d-eeeeee4e4e4e/restore?api-version=2021-07-01"
创建还原操作的请求正文

验证请求后，请使用相同的请求正文（带有轻微更改）来触发还原请求。

如以下示例所示，验证还原请求的请求正文中唯一的更改是在启动时删除 restoreRequest 该对象：

{
  "objectType": "AzureBackupRecoveryPointBasedRestoreRequest",
  "sourceDataStoreType": "VaultStore",
  "restoreTargetInfo": {

针对触发还原请求的响应

触发还原请求的操作是异步的。 因此，此操作会创建另一个需要单独跟踪的操作。

该操作返回以下响应：

名称 类型 说明
200 OK 操作已完成。
202 Accepted 接受请求。 将创建另一个操作。

POST操作提交后，它返回初始响应，连同202 AcceptedAzure-asyncOperation标头，如以下示例响应中所示：

HTTP/1.1 202 Accepted
Content-Length: 0
Expires: -1
Pragma: no-cache
Retry-After: 30

    "objectType": "OperationJobExtendedInfo"
  }
}

跟踪作业

触发还原作业后，可以使用 GET 作业 API 跟踪生成的作业 ID。

使用以下命令 GET 跟踪对触发的还原操作 jobId 的响应 中的 值：

 GET /subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx/resourceGroups/TestBkpVaultRG/providers/Microsoft.DataProtection/backupVaults/testBkpVault/backupJobs/cccc2c2c-dd3d-ee4e-ff5f-aaaaaa6a6a6a?api-version=2021-07-01

作业状态指示还原作业已完成。
