什么是 Azure 备份服务?What is the Azure Backup service?

Azure 备份服务提供简单、安全且经济高效的解决方案来备份数据,并从 Microsoft Azure 云恢复数据。The Azure Backup service provides simple, secure, and cost-effective solutions to back up your data and recover it from the Microsoft Azure cloud.

为何使用 Azure 备份?Why use Azure Backup?

Azure 备份具有以下主要优势:Azure Backup delivers these key benefits:

  • 卸载本地备份:Azure 备份提供一个简单的解决方案,可以将本地资源备份到云。Offload on-premises backup: Azure Backup offers a simple solution for backing up your on-premises resources to the cloud. 获取短期和长期备份,不需部署复杂的本地备份解决方案。Get short and long-term backup without the need to deploy complex on-premises backup solutions.
  • 备份 Azure IaaS VM:Azure 备份提供独立且隔离的备份,可以防范原始数据的意外破坏。Back up Azure IaaS VMs: Azure Backup provides independent and isolated backups to guard against accidental destruction of original data. 备份存储在可以对恢复点进行内置托管的恢复服务保管库中。Backups are stored in a Recovery Services vault with built-in managed of recovery points. 配置和可伸缩性很简单,备份经过优化,可以轻松地根据需要还原。Configuration and scalability are simple, backups are optimized, and you can easily restore as needed.
  • 轻松缩放 - Azure 备份利用 Azure 云的基础功能和无限缩放功能实现高可用性 - 无需维护,也无需监视开销。Scale easily - Azure Backup uses the underlying power and unlimited scale of the Azure cloud to deliver high-availability with no maintenance or monitoring overhead.
  • 无限数据传输:Azure 备份不会限制传输的入站或出站数据量,不会对传输的数据收费。Get unlimited data transfer: Azure Backup does not limit the amount of inbound or outbound data you transfer, or charge for the data that is transferred.
    • 出站数据是指还原操作期间从恢复服务保管库传输的数据。Outbound data refers to data transferred from a Recovery Services vault during a restore operation.
    • 如果使用 Azure 导入/导出服务执行脱机初始备份以导入大量数据,则入站数据将产生相关费用。If you perform an offline initial backup using the Azure Import/Export service to import large amounts of data, there is a cost associated with inbound data. 了解详细信息Learn more.
  • 保护数据安全:Azure 备份为保护传输中数据和静态数据提供解决方案。Keep data secure: Azure Backup provides solutions for securing data in transit and at rest.
  • 获取应用一致性备份:应用程序一致性备份意味着恢复点包含还原备份副本所需的所有数据。Get app-consistent backups: An application-consistent backup means a recovery point has all required data to restore the backup copy. Azure 备份提供了应用程序一致性备份,确保了还原数据时无需额外的修补程序。Azure Backup provides application-consistent backups, which ensure additional fixes are not required to restore the data. 还原应用程序一致型数据可减少还原时间,因此可快速恢复到运行状态。Restoring application-consistent data reduces the restoration time, allowing you to quickly return to a running state.
  • 保留短期和长期数据:可将恢复服务保管库用于短期和长期数据保留。Retain short and long-term data: You can use Recovery Services vaults for short-term and long-term data retention. Azure 不会限制恢复服务保管库中数据的保留时间长度。Azure doesn't limit the length of time data can remain in a Recovery Services vault. 可将数据保留任意时间。You can keep it for as long as you like. Azure 备份的限制为每个受保护实例仅限 9999 个恢复点。Azure Backup has a limit of 9999 recovery points per protected instance.
  • 自动存储管理 - 混合环境常常需要异类存储(部分在本地,部分在云)。Automatic storage management - Hybrid environments often require heterogeneous storage - some on-premises and some in the cloud. 通过 Azure 备份,使用本地存储设备时无需付费。With Azure Backup, there is no cost for using on-premises storage devices. Azure 备份会自动分配和管理备份存储,且采用即用即付模型,因此,你只需为消耗的存储付费。Azure Backup automatically allocates and manages backup storage, and it uses a pay-as-you-use model, so that you only pay for the storage you consume. 详细了解定价情况。Learn more about pricing.
  • 多个存储选项 - Azure 备份提供两种类型的复制来保持存储/数据的高可用性。Multiple storage options - Azure Backup offers two types of replication to keep your storage/data highly available.
    • 本地冗余存储 (LRS) 将数据中心的存储缩放单元中的数据复制三次(创建三个数据副本)。Locally redundant storage (LRS) replicates your data three times (it creates three copies of your data) in a storage scale unit in a datacenter. 数据的所有副本存在于同一区域。All copies of the data exist within the same region. LRS 是一个低成本选项,可在本地硬件故障时保护数据。LRS is a low-cost option for protecting your data from local hardware failures.
    • 异地冗余存储 (GRS) 是默认的和推荐的复制选项。Geo-redundant storage (GRS) is the default and recommended replication option. GRS 将数据复制到离源数据主位置数英里之外的次要区域中。GRS replicates your data to a secondary region (hundreds of miles away from the primary location of the source data). GRS 的成本比 LRS 的高,但 GRS 可让数据更为持久,即使出现区域性中断也是如此。GRS costs more than LRS, but GRS provides a higher level of durability for your data, even if there is a regional outage.
