Azure 备份术语表Azure Backup glossary

使用 Azure 备份时,此术语词汇表非常有用。This glossary of terms can be helpful when using Azure Backup.


  • 标有“(特定于工作负载的术语)”的术语是指仅在 Azure 备份支持的特定工作负载子集中相关的术语。Terms which are marked with the prefix "(Workload-specific term)" refer to those terms which are only relevant in the context of a specific subset of workloads that Azure Backup supports.
  • 对于 Azure 备份文档中常用但指其他 Azure 服务的术语,将提供一个指向相关 Azure 服务文档的直接链接。For terms which are used commonly in Azure Backup documentation but refer to other Azure services, a direct link is provided to the documentation of the relevant Azure service.

备用位置恢复Alternate location recovery

执行从恢复点到位置(不是在其中创建了备份的源位置)的恢复。A recovery done from the recovery point to a location other than the original location where the backups were taken. 使用 Azure VM 备份时,这意味着会将 VM 还原到执行备份的原始服务器以外的服务器。When using Azure VM backup, this would mean restoring the VM to a server other than the original server where the backups were taken.

应用程序一致性备份Application consistent backup

(特定于工作负载的术语)(Workload-specific term)

应用程序一致性备份捕获内存内容和挂起的 I/O 操作。Application-consistent backups capture memory content and pending I/O operations. 应用一致性快照使用 VSS VSS 编写器(或适用于 Linux 的前或后脚本)来确保备份之前的应用数据一致性。App-consistent snapshots use a VSS VSS writer (or pre or post scripts for Linux) to ensure the consistency of the app data before a backup occurs. 了解详细信息Learn more.

Azure 资源管理器 (ARM) 模板Azure Resource Manager (ARM) templates

请参阅 ARM 模板文档Refer to ARM templates documentation.

自动保护(用于数据库)Autoprotection (for databases)

(特定于工作负载的术语)(Workload-specific term)

自动保护是一种功能,可让你自动保护独立 SQL Server 实例或 SQL Server Always On 可用性组中的所有数据库。Autoprotection is a capability that lets you automatically protect all the databases in a standalone SQL Server instance or a SQL Server Always On availability group. 它不仅支持对现有数据库进行备份,还可保护将来可能添加的所有数据库。Not only does it enable backups for the existing databases, but it also protects all the databases that you may add in future.

可用性(存储复制类型)Availability (Storage Replication types)

Azure 备份提供了三种类型的复制来保持存储和数据的高可用性:Azure Backup offers three types of replication to keep your storage and data highly available:


本地冗余存储 (LRS) 将数据中心的存储缩放单元中的备份数据复制三次(创建三个备份数据副本)。Locally redundant storage (LRS) replicates your backup data three times (it creates three copies of your backup data) in a storage scale unit in a datacenter. 备份数据的所有副本都存在于同一区域。All copies of the backup data exist within the same region. LRS 是一种低成本选择,可在本地硬件故障时保护备份数据。LRS is a low-cost option for protecting your backup 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 将备份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 backup 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 提供更高的备份数据持久度,即使出现区域性服务中断也是如此。GRS costs more than LRS, but GRS provides a higher level of durability for your backup data, even if there's a regional outage.

备份扩展/VM 扩展Backup extensions / VM extensions

(特定于 Azure VM 工作负载类型)(Specific to Azure VM workload type)

Azure 虚拟机 (VM) 扩展是小型应用程序,可在 Azure VM 上提供部署后配置和自动化任务。Azure virtual machine (VM) extensions are small applications that provide post-deployment configuration and automation tasks on Azure VMs. Azure 备份通过为在计算机上运行的 Azure VM 代理安装一个扩展来备份 Azure VM。Azure Backup backs up Azure VMs by installing an extension to the Azure VM agent running on the machine. Azure 备份会自动管理这些扩展,用户无需手动更新这些扩展。Azure Backup automatically manages these extensions and users don't need to manually update these extensions.

备份实例/备份项Backup instance / Backup item

备份到具有特定备份和保留策略的保管库的数据源构成备份实例或备份项。A datasource backed up to a vault with a particular backup and retention policy constitutes a backup instance or a backup item.

备份规则/备份策略Backup rule / Backup policy

备份规则是用户定义的规则,它指定在数据源上执行备份的时间和频率。A backup rule is a user-defined rule that specifies when and how often backups should be performed on a datasource. 对于某些工作负载类型,备份策略还提供了一种指定要应用于数据源的快照方法(完全、增量、差异)的方法。For some workload types, backup policy also provides a way to specify the snapshot method to be applied on the datasource (full, incremental, differential). 备份策略通常作为备份规则和保留规则的组合创建。Backup policies are often created as a combination of backup rules and retention rules.

备份保管库Backup vault

类型为 Microsoft.DataProtection/BackupVaults 的 Azure 资源管理器资源。An Azure Resource Manager resource of type Microsoft.DataProtection/BackupVaults. 目前,备份保管库用于备份 Azure Databases for PostgreSQL 服务器。Currently, Backup vaults are used to back up Azure Databases for PostgreSQL Server. 详细了解备份保管库Learn more about Backup vaults.

在两个连续备份之间备份的数据更改百分比。The percent of change in the data being backed up between two consecutive backups. 这可能是由于增加了新数据,或者修改或删除了现有数据。This could be because of addition of new data, or the modification or deletion of existing data.

崩溃一致性备份Crash-consistent backup

(特定于工作负载的术语)(Workload-specific term)

如果在备份时 Azure VM 关闭,则往往会发生崩溃一致性快照。Crash-consistent snapshots typically occur if an Azure VM shuts down at the time of backup. 仅会捕获和备份备份时磁盘上已存在的数据。Only the data that already exists on the disk at the time of backup is captured and backed up. 了解详细信息Learn more.

GFS 备份策略GFS Backup Policy

GFS(祖父-父-子)备份策略使你能够定义每周、每月和每年的备份计划,以及每日备份计划。A GFS (Grandfather-father-son) backup policy is one that enables you to define weekly, monthly, and yearly backup schedules in addition to the daily backup schedule. 每周备份称为“子”,每月备份称为“父”,每年的备份称为“祖父”。The weekly backups are known "sons", the monthly backups are known as "fathers" and the yearly backups are known as "grandfathers". 可以将每组备份副本配置为保留不同的时间,以便对备份副本的保留选择进行更多自定义。Each of these sets of backup copies can be configured to be retained for different durations of time, allowing for more customization of retention choices for backup copies. GFS 策略有助于以更高效存储的方式长时间保留备份。GFS policies are useful in retaining backups for a long period of time in a more storage-efficient manner.

即时还原Instant restore

(特定于工作负载的术语)即时还原涉及直接从计算机的备份快照还原计算机(而不是从保管库中的快照副本还原计算机)。(Workload specific term) Instant restore involves restoring a machine directly from its backup snapshot rather than from the copy of the snapshot in the vault. 即时还原比从保管库还原快。Instant restores are faster than restores from a vault. 可用的即时还原点数取决于为快照配置的保留持续时间。The number of instant restore points available depends on the retention duration configured for snapshots. 目前仅适用于 Azure VM 备份。Currently applicable for Azure VM backup only.

执行从还原点到源位置(已在其中创建了备份)的恢复,将其替换为存储在恢复点中的状态。A recovery done from the restore point to the source location from where the backups were taken, replacing it with the state stored in the recovery point. 使用 Azure VM 备份时,这意味着将 VM 还原到进行备份的原始服务器。When using Azure VM backup, this would mean restoring the VM to the original server where the backups were taken.


(特定于工作负载的术语)(Workload-specific term)

使用 MARS 代理向/从 Azure 备份或还原本地计算机时,通行短语用于加密和解密数据。A passphrase is used to encrypt and decrypt data while backing up or restoring your on-premises or local machine using the MARS agent to or from Azure.

受保护的实例Protected instance

受保护的实例是指用于配置 Azure 备份的计算机、物理或虚拟服务器。A protected instance refers to the computer, physical or virtual server you use to configure the backup to Azure. 从计费角度来看,计算机的受保护的实例计数是计算机前端大小的函数。From a billing standpoint, Protected Instance Count for a machine is a function of its frontend size. 因此,一个备份实例(例如,一个备份到 Azure 的 VM)可以与多个受保护的实例相对应,具体取决于其前端大小。Thus, a single backup instance (such as a VM backed up to Azure) can correspond to multiple protected instances, depending on its frontend size. 了解详细信息Learn more.

区域对由同一地理位置中的两个区域组成。A regional pair consists of two regions within the same geography. 一个是主要区域,另一个是次要区域。One is the primary region, and the other is the secondary region. 某些 Azure 服务(包括具有 GRS 设置的 Azure 备份)使用配对区域,以确保业务连续性并防止数据丢失。Paired regions are used by some Azure services (including Azure Backup with GRS settings) to ensure business continuity and protect against data loss. 了解详细信息Learn more.

软删除Soft delete

软删除是一项有助于防止意外删除备份数据的功能。Soft delete is a feature that helps guard against accidental deletion of backup data. 在使用软删除的情况下,即使恶意行动者删除了备份(或用户意外删除了备份数据),备份数据也仍会保留一段额外的时间,因此可以恢复该备份项,而不会丢失数据。With soft delete, even if a malicious actor deletes a backup (or backup data is accidentally deleted), the backup data is retained for an additional period of time, allowing the recovery of that backup item with no data loss. 了解详细信息Learn more.
