将存储添加到 Azure 备份服务器Add storage to Azure Backup Server

Azure 备份服务器 V2 及更高版本支持新式备份存储,后者可提供节省 50% 的存储、快三倍的备份以及更高效的存储。Azure Backup Server V2 and later supports Modern Backup Storage that offers storage savings of 50 percent, backups that are three times faster, and more efficient storage. 它还提供可感知工作负荷的存储。It also offers workload-aware storage.

Note

若要使用新式备份存储,必须在 Windows Server 2016 上运行备份服务器 V2 或 V3,或者在 Windows Server 2019 上运行备份服务器 V3。To use Modern Backup Storage, you must run Backup Server V2 or V3 on Windows Server 2016 or V3 on Windows Server 2019. 如果在早期版本的 Windows Server 上运行备份服务器 V2,则 Azure 备份服务器无法利用新式备份存储。If you run Backup Server V2 on an earlier version of Windows Server, Azure Backup Server can't take advantage of Modern Backup Storage. 而是采用与备份服务器 V1 相同的方式来保护工作负载。Instead, it protects workloads as it does with Backup Server V1. 有关详细信息,请参阅备份服务器版本保护矩阵For more information, see the Backup Server version protection matrix.

备份服务器中的卷Volumes in Backup Server

备份服务器 V2 或更高版本可接受存储卷。Backup Server V2 or later accepts storage volumes. 添加卷时,备份服务器会将卷格式化为 Modern Backup Storage 所需的复原文件系统 (ReFS)。When you add a volume, Backup Server formats the volume to Resilient File System (ReFS), which Modern Backup Storage requires. 若要添加卷以及以后在需要时扩展它,建议使用以下工作流:To add a volume, and to expand it later if you need to, we suggest that you use this workflow:

  1. 在 VM 上设置备份服务器。Set up Backup Server on a VM.
  2. 在存储池中的虚拟磁盘上创建卷:Create a volume on a virtual disk in a storage pool:
    1. 将磁盘添加到存储池,然后使用简单布局创建虚拟磁盘。Add a disk to a storage pool and create a virtual disk with simple layout.
    2. 添加任何其他磁盘,然后扩展虚拟磁盘。Add any additional disks, and extend the virtual disk.
    3. 在虚拟磁盘上创建卷。Create volumes on the virtual disk.
  3. 将卷添加到备份服务器。Add the volumes to Backup Server.
  4. 配置可感知工作负荷的存储。Configure workload-aware storage.

为 Modern Backup Storage 创建卷Create a volume for Modern Backup Storage

使用具有卷的备份服务器 V2 或更高版本作为磁盘存储可以帮助维护对存储的控制权。Using Backup Server V2 or later with volumes as disk storage can help you maintain control over storage. 卷可以是单个磁盘。A volume can be a single disk. 但是,如果要在将来扩展存储,请通过使用存储空间创建的磁盘来创建卷。However, if you want to extend storage in the future, create a volume out of a disk created by using storage spaces. 如果要为备份存储扩展卷,这可能有所帮助。This can help if you want to expand the volume for backup storage. 本部分提供有关使用此设置创建卷的最佳做法。This section offers best practices for creating a volume with this setup.

  1. 在“服务器管理器”中,然后选择“文件和存储服务” > “卷” > “存储池”。In Server Manager, select File and Storage Services > Volumes > Storage Pools. 在“物理磁盘”,选择“新建存储池”。Under PHYSICAL DISKS, select New Storage Pool.

    创建新存储池

  2. 在“任务”下拉框中,选择“新建虚拟磁盘”。In the TASKS drop-down box, select New Virtual Disk.

    添加虚拟磁盘

  3. 选择存储池,然后选择“添加物理磁盘”。Select the storage pool, and then select Add Physical Disk.

    添加物理磁盘

  4. 选择物理磁盘,然后选择“扩展虚拟磁盘”。Select the physical disk, and then select Extend Virtual Disk.

    扩展虚拟磁盘

  5. 选择虚拟磁盘,然后选择“新建卷” 。Select the virtual disk, and then select New Volume.

    创建新卷

  6. 在“选择服务器和磁盘” 对话框中,选择服务器和新磁盘。In the Select the server and disk dialog, select the server and the new disk. 然后,选择“下一步” 。Then, select Next.

    选择服务器和磁盘

将卷添加到备份服务器磁盘存储Add volumes to Backup Server disk storage

Note

  • 仅将一个磁盘添加到池,使列计数保持为 1。Add only one disk to the pool to keep the column count to 1. 然后,可以根据需要添加磁盘。You can then add disks as needed afterwards.
  • 如果一次将多个磁盘添加到存储池,则磁盘数将存储为列数。If you add multiple disks to the storage pool at a go, the number of disks is stored as the number of columns. 添加更多磁盘时,它们只能是列数的倍数。When more disks are added, they can only be a multiple of the number of columns.

若要将卷添加到备份服务器,请在“管理” 窗格中,重新扫描存储,然后选择“添加” 。To add a volume to Backup Server, in the Management pane, rescan the storage, and then select Add. 可用于为备份服务器存储添加的所有卷的列表随即出现。A list of all the volumes available to be added for Backup Server Storage appears. 将可用卷添加到所选卷的列表之后,可以为它们提供友好名称以帮助管理它们。After available volumes are added to the list of selected volumes, you can give them a friendly name to help you manage them. 若要将这些卷格式化为 ReFS 以便备份服务器可以利用 Modern Backup Storage 的优点,请选择“确定” 。To format these volumes to ReFS so Backup Server can use the benefits of Modern Backup Storage, select OK.

添加可用卷

设置可感知工作负荷的存储Set up workload-aware storage

借助可感知工作负荷的存储,可以选择优先存储某些类型的工作负荷的卷。With workload-aware storage, you can select the volumes that preferentially store certain kinds of workloads. 例如,可以将支持较高每秒输入/输出操作次数 (IOPS) 的昂贵卷设置为仅存储需要频繁的高容量备份的工作负荷。For example, you can set expensive volumes that support a high number of input/output operations per second (IOPS) to store only the workloads that require frequent, high-volume backups. 一个示例是具有事务日志的 SQL Server。An example is SQL Server with transaction logs. 可以将备份频率较低的其他工作负荷(如 VM)备份到低成本卷。Other workloads that are backed up less frequently, like VMs, can be backed up to low-cost volumes.

Update-DPMDiskStorageUpdate-DPMDiskStorage

可以使用 PowerShell cmdlet Update-DPMDiskStorage(它可更新 Azure 备份服务器上存储池中的卷的属性)设置可感知工作负荷的存储。You can set up workload-aware storage by using the PowerShell cmdlet Update-DPMDiskStorage, which updates the properties of a volume in the storage pool on an Azure Backup Server.

语法:Syntax:

Parameter Set: Volume

Update-DPMDiskStorage [-Volume] <Volume> [[-FriendlyName] <String> ] [[-DatasourceType] <VolumeTag[]> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

以下屏幕截图显示 PowerShell 窗口中的 Update-DPMDiskStorage cmdlet。The following screenshot shows the Update-DPMDiskStorage cmdlet in the PowerShell window.

PowerShell 窗口中的 Update-DPMDiskStorage 命令

使用 PowerShell 进行的更改会在备份服务器管理员控制台中得到反映。The changes you make by using PowerShell are reflected in the Backup Server Administrator Console.

管理员控制台中的磁盘和卷

将旧存储迁移到 Modern Backup StorageMigrate legacy storage to Modern Backup Storage

升级到或安装备份服务器 V2 并将操作系统升级到 Windows Server 2016 之后,可更新保护组以使用新式备份存储。After you upgrade to or install Backup Server V2 and upgrade the operating system to Windows Server 2016, update your protection groups to use Modern Backup Storage. 默认情况下,保护组不会进行更改。By default, protection groups are not changed. 它们会继续按照初始设置运行。They continue to function as they were initially set up.

可以选择更新保护组以使用 Modern Backup Storage。Updating protection groups to use Modern Backup Storage is optional. 若要更新保护组,请使用“保留数据”选项停止所有数据源的保护。To update the protection group, stop protection of all data sources by using the retain data option. 然后,将数据源添加到新保护组。Then, add the data sources to a new protection group.

  1. 在管理员控制台中,选择“保护”功能。In the Administrator Console, select the Protection feature. 在“保护组成员”列表中,右键单击成员,然后选择“停止保护成员”。In the Protection Group Member list, right-click the member, and then select Stop protection of member.

    停止保护成员

  2. 在“从组中删除”对话框中,查看存储池的已用磁盘空间和可用空闲空间。In the Remove from Group dialog box, review the used disk space and the available free space for the storage pool. 默认设置是在磁盘上保留恢复点,并让它们可以按照关联的保留策略过期。The default is to leave the recovery points on the disk and allow them to expire per their associated retention policy. 单击 “确定”Click OK.

    如果要立即将已用磁盘空间返回到可用存储池,请选中“删除磁盘上的副本”复选框以删除与成员关联的备份数据(和恢复点)。If you want to immediately return the used disk space to the free storage pool, select the Delete replica on disk check box to delete the backup data (and recovery points) associated with that member.

    “从组中删除”对话框

  3. 创建一个使用 Modern Backup Storage 的保护组。Create a protection group that uses Modern Backup Storage. 包括未受保护的数据源。Include the unprotected data sources.

添加磁盘以增大旧存储Add disks to increase legacy storage

如果要将旧存储与备份服务器一起使用,则可能需要添加磁盘以增大旧存储。If you want to use legacy storage with Backup Server, you might need to add disks to increase legacy storage.

添加磁盘存储:To add disk storage:

  1. 在管理员控制台中,选择“管理” > “磁盘存储” > “添加”。In the Administrator Console, select Management > Disk Storage > Add.

    “添加磁盘存储”对话框

  2. 在“添加磁盘存储”对话框中,选择“添加磁盘”。In the Add Disk Storage dialog, select Add disks.

  3. 在可用磁盘的列表中,依次选择要添加的磁盘、“添加”、“确定”。In the list of available disks, select the disks you want to add, select Add, and then select OK.
