保护域 -bASEDdATAp使用棱镜元素配置轮换。Nutanix支持几种类型的保护策略，包括一对一或一对一的复制。这些策略如下：

  • 每vm备份。在分支机构环境中，将某些VM指定为备份到其他站点的能力特别有用。通常，只有在分支位置运行的VM的子集需要定期备份到中央站点。但是，当复制建立在传统的存储阵列上时，这种每vm的粒度水平是不可能的。在这些传统环境中，复制是在粗晶粒水平，整个lun或卷中进行，因此难以管理多个站点的复制。
  • 选择性双向复制。除了复制选定的VM外，灵活的复制解决方案还必须容纳各种企业拓扑。简单地将VM从一个活动站点复制到指定的被动站点不再足够，如果发生灾难，可以“点亮”。支持不同的拓扑要求数据和VM可以通过双向复制。
  • 同步数据存储复制（Metro可用性）。在现场灾难时，可以在两个站点上跨越两个站点，以提供无缝保护。

Protection Domain\u2013<\/span>B<\/span>ased <\/span>D<\/span>ata <\/span>P<\/span>rotection is configured using Prism Element<\/span>. Nutanix supports several types of protection strategies including one-to-one or one-to-many replication. These strategies are as follows:<\/span><\/span><\/p>
  • Per-VM Backup.<\/span><\/strong> The ability to designate certain VMs for backup to a different site is particularly useful in branch office environments. Typically, only a subset of VMs running in a branch location require regular back up to a central site. Such per-VM level of granularity, however, is not possible when replication is built on traditional storage arrays. In these legacy environments replication is performed at a coarse grain level, entire LUNs or volumes, making it difficult to manage replication across multiple sites.<\/span><\/span><\/li>\t
  • Selective Bi-directional Replication.<\/span><\/strong> In addition to replicating selected VMs, a flexible replication solution must also accommodate a variety of enterprise topologies. It is no longer sufficient to simply replicate VMs from one active site to a designated passive site, which can be \"lit up\" in event of a disaster. Supporting different topologies demands that data and VMs can be replicated bi-directionally.<\/span><\/span><\/li>\t
  • Synchronous Datastore Replication (metro availability).<\/span><\/strong> Datastores can be spanned across two sites to provide seamless protection in the event of a site disaster.<\/span><\/span><\/li><\/ul>
