BackupTables是登录备份进程的方法。客户可以为每个表格提供一个TableKeyInfo。例如，如果拆分密钥是GUID，下面是如何援引BackupTables方法： CloudTableClient tableClient = new CloudTableClient(account.TableEndpoint.AbsoluteUri, account.Credentials); CloudBlobClient blobClient = new CloudBlobClient(account.BlobEndpoint.AbsoluteUri, account.Credentials);   // The more keys listed here, the better for scale string[] rangeQueries = new string[] { "3", "8", "a", "f" }; string[] tableNames = new string[] { "Customers", "Orders" };   List<TableKeysInfo> keyInfo = new List<TableKeysInfo>(); foreach(string tableName in tableNames) {      keyInfo.Add( new TableKeysInfo(tableName, rangeQueries)); }   BackupTables(tableClient, blobClient, keyInfo);

      BackupTables现在已经完成每个表格以及表格中每个排列范围的迭代，它援引了BackupTableRange，而BackupTableRange负责将指定排列范围的结果集保存到Blob中。简单地说，此示例按顺序完成上述操作，以加快从Blob中恢复实体数据的进程，就需要将下面的内容并入操作之中。 /// <summary> /// Backup each table to blobs. Each table will be stored under a container with same name as the table. /// </summary> /// <param name="tableClient"></param> /// <param name="blobClient"></param> /// <param name="tablesToBackup"> /// The tablesToBackup will contain the table name to a list of keys that will be used to partition the query /// </param> public static void BackupTables(CloudTableClient tableClient,                    CloudBlobClient blobClient, List<TableKeysInfo> tablesToBackup) {     if (tableClient == null)     {         throw new ArgumentNullException("tableClient");     }       try     {         // we will use this id as the folder name. The blobs will be stored under:         //  <lower cased table name>/<backupid>/         string backupId = DateTime.UtcNow.ToString("yy-MM-dd-HH-mm-ss");           // list each range in each table and backup up each range         foreach (TableKeysInfo tableKeysInfo in tablesToBackup)         {             CloudBlobContainer container = blobClient.GetContainerReference(tableKeysInfo.TableName.ToLower());             container.CreateIfNotExist();               foreach (PartitionKeyRange range in tableKeysInfo.KeyRangeList)             {                 BackupTableRange(tableClient, container, tableKeysInfo.TableName, range, backupId);             }         }     }     catch (Exception e)     {         // TODO: log exception for debugging purpose and then rethrow           throw;     } }
