本文介绍如何执行管理和监视由 Azure 备份所备份的 Azure 文件共享的任务。

监视作业

Azure 备份服务会触发在后台运行的作业。这包括触发备份、还原操作和禁用备份等方案。可以使用作业的 ID 跟踪这些作业。

从操作中获取作业信息

操作（例如触发备份）将始终返回 jobID 作为响应。

例如：触发备份 REST API操作的最终响应如下所示：

{
    "id": "c3a52d1d-0853-4211-8141-477c65740264",
    "name": "c3a52d1d-0853-4211-8141-477c65740264",
    "status": "Succeeded",
    "startTime": "2020-02-03T18:10:48.296012Z",
    "endTime": "2020-02-03T18:10:48.296012Z",
    "properties": {
        "objectType": "OperationStatusJobExtendedInfo",
        "jobId": "e2ca2cf4-2eb9-4d4b-b16a-8e592d2a658b"
    }
}

Azure 文件共享备份作业由“jobId”字段予以标识，并且可以如此处所述使用简单的 GET 请求进行跟踪。

跟踪作业

GET https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupJobs/{jobName}?api-version=2019-05-13

{JobName} 是上面提到的“jobId”。响应始终为“200 正常”其中“status”字段指示作业的状态。当状态为“Completed”或“CompletedWithWarnings”之后，“extendedInfo”部分显示关于作业的更多详细信息。

GET https://management.chinacloudapi.cn/Subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.RecoveryServices/vaults/azurefilesvault/backupJobs/e2ca2cf4-2eb9-4d4b-b16a-8e592d2a658b?api-version=2019-05-13'

响应

名称	Type	说明
200 正常	JobResource	确定

响应示例

提交“GET”URI 后，将返回 200 响应。

        "activityId": "3677cec0-942d-4eac-921f-8f3c873140d7"
    }
}

修改策略

若更改受保护文件共享的策略，可以使用与启用保护相同的格式。只需在请求策略中提供新的策略 ID 并提交请求即可。

例如，若要将“testshare”的保护策略从“schedule1”更改为“schedule2”，请在请求正文中提供“schedule2”ID。

{
  "properties": {
    "protectedItemType": "AzureFileShareProtectedItem",
    "sourceResourceId": "/subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/AzureFiles/providers/Microsoft.Storage/storageAccounts/testvault2",
    "policyId": "/Subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.RecoveryServices/vaults/azurefilesvault/backupPolicies/schedule2"
  }
}

停止保护，但保留现有数据

可以删除受保护文件共享的保护，但保留已备份的数据。为此，请在用于启用备份和提交请求的请求正文中删除策略。删除与策略的关联后，将不再触发备份，也不会创建新的恢复点。

{
  "properties": {
    "protectedItemType": "AzureFileShareProtectedItem",
    "sourceResourceId": "/subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/AzureFiles/providers/Microsoft.Storage/storageAccounts/testvault2",
    "policyId": "" ,
"protectionState":"ProtectionStopped"
  }
}

示例响应

停止对文件共享的保护是一个异步操作。此操作会创建另一个需要跟踪的操作。它将返回两个响应：创建另一个操作时为 202（已接受），该操作完成时为 200。

成功接受操作时的响应标头：

然后通过 GET 命令并使用位置标头或 Azure-AsyncOperation 标头跟踪生成的操作：

响应正文

{
    "id": "b300922a-ad9c-4181-b4cd-d42ea780ad77",
    "name": "b300922a-ad9c-4181-b4cd-d42ea780ad77",
    "status": "Succeeded",
    "startTime": "2020-02-06T06:42:24.4001299Z",
    "endTime": "2020-02-06T06:42:24.4001299Z",
    "properties": {
        "objectType": "OperationStatusJobExtendedInfo",
        "jobId": "7816fca8-d5be-4c41-b911-1bbd922e5826"
    }
}

停止保护并删除数据

若要删除对受保护文件共享的保护并删除备份数据，请执行此处详述的删除操作。

DELETE https://management.chinacloudapi.cn/Subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.RecoveryServices/vaults/{vaultName}/backupFabrics/{fabricName}/protectionContainers/{containerName}/protectedItems/{protectedItemName}?api-version=2019-05-13

参数 {containerName} 和 {protectedItemName} 如此处所设置。

下面的示例触发操作以停止保护受“azurefilesvault”保护的“testshare”文件共享。

DELETE https://management.chinacloudapi.cn/Subscriptions/ef4ab5a7-c2c0-4304-af80-af49f48af3d1/resourceGroups/azurefiles/providers/Microsoft.RecoveryServices/vaults/azurefilesvault/backupFabrics/Azure/protectionContainers/StorageContainer;Storage;AzureFiles;testvault2/protectedItems/azurefileshare;testshare?api-version=2016-12-01

响应

删除保护是一种异步操作。此操作会创建另一个需要单独跟踪的操作。它将返回两个响应：创建另一个操作时为 202（已接受），然后在该操作完成时为 204（无内容）。
