vReplicator v2.5 Chapter 4 Using vReplicator 93

Replication Type

(radio buttons)

There are two replication types—Hybrid and Differential.

Hybrid: A faster method of replication, hybrid replicates as a

function of change over time. No scanning is needed and snapshots

can be taken at shorter intervals. Using this method, a snapshot

remains open continuously.

Differential: Using this method, two replication passes are

completed. The source VM’s current data is compared to the

changed data that is stored on the data map. These changes are

replicated block by block and committed to the destination

machine. During differential replication, a snapshot is left open

only during a replication pass.

Fixed replication refers to jobs that are executed at specified points

on a timeline.

Sliding replication refers to jobs that are executed at a sliding

frequency.

Use the Days, Hours, and Minutes spin boxes to set a timeframe for

the job. These values refer to the period between replications. The

shorter the timeframe, the more up-to-date the VM will be as a

result of the replication. A shorter timeframe requires more host

resources, which can compromise VM performance temporarily.

Note: The replication job will start automatically as soon as the

initial copying completes.

Next Start Time

(spin box)
