MABS V3 RTM 中的新增功能What's new in MABS V3 RTM

Microsoft Azure 备份服务器版本 3 (MABS V3) 包含重要的 bug 修复、Windows Server 2019 支持、SQL 2017 支持以及其他功能和增强功能。Microsoft Azure Backup Server version 3 (MABS V3) includes critical bug fixes, Windows Server 2019 support, SQL 2017 support, and other features and enhancements. 若要查看 MABS V3 中已修复的 bug 列表和安装说明,请参阅知识库文章 4457852To view the list of bugs fixed and the installation instructions for MABS V3, see KB article 4457852.

MABS V3 包含以下功能:The following features are included in MABS V3:

卷到卷的迁移Volume to Volume migration

发布 MABS V2 中的新式备份存储 (MBS) 时,我们宣布推出了工作负荷感知的存储,在其中可以根据存储属性,将某些工作负荷配置为备份到特定的存储。With Modern Backup Storage (MBS) in MABS V2, we announced Workload aware storage, where you configure certain workloads to be backed up to specific storage, based on storage properties. 但是,在配置后,你可能发现,需要将某些数据源的备份移到其他存储,以优化资源利用率。However, after configuration, you may find a need to move backups of certain data sources to other storage for optimized resource utilization. 在 MABS V3 中可以迁移备份,并通过三个步骤将其配置为存储到其他卷。MABS V3 gives you the capability to migrate your backups and configure them to be stored to a different volume in three steps.

防止意外的数据丢失Prevent unexpected data loss

在企业中,MABS 由管理员团队管理。In enterprises, MABS is managed by a team of administrators. 尽管用于备份的存储有指导原则可供参考,但在 MABS 中提供错误的卷作为备份存储可能会导致关键数据丢失。While there are guidelines on storage that should be used for backups, an incorrect volume given to MABS as backup storage may lead to loss of critical data. 在 MABS V3 中,可以使用这些 PowerShell cmdlet 将这些卷配置为不可用于存储,来防止这种情况。With MABS V3, you can prevent such scenarios by configuring those volumes as the ones that aren't available for storage using these PowerShell cmdlets.

自定义大小分配Custom size allocation

新式备份存储 (MBS) 根据需要消耗少量的存储。Modern Backup Storage (MBS) consumes storage thinly, as and when needed. 为此,在配置用于保护后,MABS 会计算备份数据的大小。To do so, MABS calculates the size of the data being backed up when it's configured for protection. 但是,如果要同时备份许多的文件和文件夹(例如,在文件服务器中备份时),大小计算可能会花费很长时间。However, if many files and folders are being backed up together, as in the case of a file server, size calculation can take long time. 在 MABS V3 中,可将 MABS 配置为接受默认卷大小而不是计算每个文件的大小,从而可以节省时间。With MABS V3, you can configure MABS to accept the volume size as default, instead of calculating the size of each file, which saves time.

针对 RCT VM 优化的一致性检查Optimized CC for RCT VMs

MABS 使用 RCT(Hyper-V 中的本机更改跟踪),可以在发生 VM 崩溃等情况时减少非常耗时的一致性检查的需求。MABS uses RCT (the native change tracking in Hyper-V), which decreases the need for time-consuming consistency checks in scenarios as VM crashes. 与基于 VSS 快照的备份提供的更改跟踪相比,RCT 提供更好的复原能力。RCT provides better resiliency than the change tracking provided by VSS snapshot-based backups. 在执行任何一致性检查期间,MABS V3 只会传输更改的数据,因而可以进一步优化网络和存储消耗。MABS V3 optimizes network and storage consumption further by transferring only the changed data during any consistency checks.

TLS 1.2 支持Support to TLS 1.2

TLS 1.2 是 Microsoft 建议的通信方式,并采用一流的加密。TLS 1.2 is the secure way of communication suggested by Microsoft with best-in class encryption. MABS 现在支持 MABS 与受保护服务器之间的 TLS 1.2 通信,以进行基于证书的身份验证和云备份。MABS now supports TLS 1.2 communication between MABS and the protected servers, for certificate-based authentication, and for cloud backups.

VMware VM 保护支持VMware VM protection support

现在,支持对生产部署使用 VMware VM 备份。VMware VM backup is now supported for production deployments. MABS V3 为 VMware VM 保护提供以下功能:MABS V3 offers the following for VMware VM protection:

  • 支持 vCenter 和 ESXi 6.5、5.5 和 6.0。Support for vCenter and ESXi 6.5, along with support for 5.5 and 6.0.
