Array-independent, host-based VM replication within or between sites, provided as a vCenter extension with an appliance at each site; VMware Live Site Recovery can use it instead of array replication.

Each book explains vSphere Replication in context, with comparison tables and the common traps.
Terms in this definition
- vCenter
Management software for VMs, clusters and ESX hosts. Each domain in VCF gets a dedicated one.
- LSDOU
The sequence in which Group Policy is processed: the local policy first, followed by site, domain and organisational unit policies. The nearest, last-processed setting takes effect unless Enforced or Block Inheritance alters that.
- VMware Live Site Recovery
VM disaster recovery orchestration that plugs into vCenter, letting teams plan, test and execute failover between a protected site and a recovery site. Replication underneath can be vSphere Replication, array-based or vVols; VCF customers get it through the advanced service called VMware Live Recovery.
Related terms
- Enhanced replication
With an Advanced Cyber Compliance or Site Recovery Manager subscription, this vSphere Replication mode supports one-minute RPOs. Data skips the replication appliance and lands directly on hosts in the target cluster, which must run vCenter and ESX 8.0 Update 2 or newer, and the traffic is rebalanced half-hourly.
- MPIT
Multiple point in time instances. With this vSphere Replication option, the target site retains as many as 24 snapshots of a replicated machine, letting a recovered VM roll back to a moment before data was corrupted.
- protection group
VMs that VMware Live Site Recovery protects and recovers as a unit. A group may appear in several recovery plans but is limited to one replication type: vSphere Replication, vVols or array-based.
- SRA
Vendor-supplied software, installed for VMware Live Site Recovery at both sites, that allows array-based replication (storage arrays copying data from protected to recovery site). Not required when vSphere Replication is used.
