Protection Domain–Based Data Protection is configured using Prism Element. Nutanix supports several types of protection strategies including one-to-one or one-to-many replication. These strategies are as follows:

  • Per-VM Backup. 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.
  • Selective Bi-directional Replication. 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.
  • Synchronous Datastore Replication (metro availability). Datastores can be spanned across two sites to provide seamless protection in the event of a site disaster.
