vReplicator v2.5 Chapter 2 Installation 7

vReplicator Overview

Reliable business continuity and disaster recovery (DR) strategies deliver comprehensive

and consistent results. Replication plays a key role in this process. If done well,

replication can restore systems securely while enhancing performance and minimizing

interruption.

VMware Infrastructure 3 (VI3) provides a solid platform for replication. vReplicator 2.5

was designed to be the definitive replication solution for VI3. vReplicator captures the

complete VM image—OS, configuration settings, applications, and data. vReplicator’s

Windows-based interface offers easy access and navigation. All potential source and

destination machines display in a tree structure.

There are two replication methods and schedules from which to choose. Once a job is

configured, you can run it at any time—even off-schedule. You can run jobs between

hosts, VMs, or dissimilar hardware platforms. With the help of vzBoost, vReplicator does

its work quickly—while the source machine is running—without compromising system

resources. vReplicator monitors VM and host performance patterns. You can use this

information to improve replication job scheduling.

Snapshots

vReplicator uses VMware snapshots during replications to ensure that the entire VM

image is captured. Snapshots keep each replication job current by allowing you to revert

to a previous point in time, merging that data with the current data.

vReplicator does not support third party tools that use snapshots. vRanger Pro is an

exception because it shares a file-locking mechanism with vReplicator that prevents

failures and data loss, even when the applications are running concurrently against the

same VM. When vReplicator attempts a replication, it needs access to the source VM’s

disk files. For vRanger Pro to create a backup, it requires similar access. If a replication

job is in process when vRanger Pro attempts a backup, vRanger Pro will pause until the

replication pass has completed. Alternately, if a backup job is in process when

vReplicator attempts a replication, the replication pass will pause to allow the backup to

complete.

Warning: During hybrid replication, a snapshot remains open continuously. This can

compromise vRanger Pro’s ability to complete differential backups of a VM being

replicated. When you initiate a hybrid replication, you should not use vRanger Pro to

perform a differential backup of that VM. In this case, it is best to complete a full backup

of the machine.

vReplicator can connect with the source and destination machines directly or through

VC. There are several advantages to integrating VC with vReplicator. VC serves as a host

management interface, organizing data stores, hosts, VMs, and other objects in a tree

structure. VC makes it possible for vReplicator to monitor the movement of VMs
