Reference Guide

To enable replication on volumes, go to Storage >> Disks and right-click on the primary volume on which you want to enable
replication. Then follow these steps:
● Select Replication and click Enable
● Select the log volume for the primary site
● Select the Replica volume and associated log volume for the secondary site
● Overwrite the destination volume unless you have a seeded disk
● Select the mode of replication
● Complete the wizard
This enables replication on the volume after the initial block copy. The initial block copy process can take a few minutes to a few
hours, depending on the size of the volume.
Test-SRTopology
This cmdlet validates a potential replication partnership between source and destination computers. Follow these steps:
● Create a local CSVFS volume, for example 1 TB.
● Create a local log volume (ReFS), for example 50 GB.
● Create a Replica volume (ReFS), for example 1 TB (Ensure that the local and replica volumes are the same size).
● Create a Replica-log volume (ReFS), for example 50 GB.
