具有低或无网络宽带的大型数据集的数据传输Data transfer for large datasets with low or no network bandwidth

本文概述了在环境中已限制为无网络宽带并且正在计划传输大型数据集时的数据传输解决方案。This article provides an overview of the data transfer solutions when you have limited to no network bandwidth in your environment and you are planning to transfer large data sets. 本文还介绍了针对此情况的推荐数据传输选项和相应的关键功能矩阵。The article also describes the recommended data transfer options and the respective key capability matrix for this scenario.

若要查看所有可用数据传输选项的概述,请转到选择一个 Azure 数据传输解决方案To understand an overview of all the available data transfer options, go to Choose an Azure data transfer solution.

脱机传输或网络传输Offline transfer or network transfer

大型数据集意味着具有几个 TB 到几个 PB 的数据。Large datasets imply that you have few TBs to few PBs of data. 网络带宽已限制为无、网络速度较慢或不可靠。You have limited to no network bandwidth, your network is slow, or it is unreliable. 此外:Also:

  • 受到来自 Internet 服务提供商 (ISP) 的网络传输成本的限制。You are limited by costs of network transfer from your Internet Service Providers (ISPs).
  • 安全或组织政策不允许在处理敏感数据时使用出站连接。Security or organizational policies do not allow outbound connections when dealing with sensitive data.

在所有上述实例中,使用物理设备进行一次性大容量数据传输。In all the above instances, use a physical device to do a one-time bulk data transfer. 选择 Azure 提供的 Data Box Disk 设备,或者使用你自己的磁盘进行导入/导出。Choose Data Box Disk devices which are supplied by Azure, or Import/Export using your own disks.

若要确认物理设备是否是正确的选项,请使用下表。To confirm whether a physical device is the right option, use the following table. 它显示各种可用宽带(假设利用率为 90%)的网络数据传输的预测时间。It shows the projected time for network data transfer, for various available bandwidths (assuming 90% utilization). 如果预测网络传输速度很慢,应使用物理设备。If network transfer is projected to be too slow, you should use a physical device.

网络传输或脱机传输

此方案中可用的选项是用于 Azure Data Box 脱机传输或 Azure 导入/导出的设备。The options available in this scenario are devices for Azure Data Box offline transfer or Azure Import/Export.

  • 用于脱机传输的 Azure Data Box 系列 – 当受到时间、网络可用性或成本的限制时,使用 Azure 提供的 Data Box 设备将大量数据移到 Azure。Azure Data Box family for offline transfers – Use devices from Azure-supplied Data Box devices to move large amounts of data to Azure when you're limited by time, network availability, or costs. 使用工具(例如 Robocopy)复制本地数据。Copy on-premises data using tools such as Robocopy. 根据要传输的数据的大小,可以选择 Data Box Disk。Depending on the data size intended for transfer, you can choose Data Box Disk.
  • Azure 导入/导出 - 通过寄送自己的磁盘驱动器,使用 Azure 导入/导出服务安全地将大量数据导入 Azure Blob 存储和 Azure 文件。Azure Import/Export – Use Azure Import/Export service by shipping your own disk drives to securely import large amounts of data to Azure Blob storage and Azure Files. 此外,还可以使用此服务将数据从 Azure Blob 存储传输到磁盘驱动器,然后再寄送到本地站点。This service can also be used to transfer data from Azure Blob storage to disk drives and ship to your on-premises sites.
