About setting up replication
This chapter guides you through the process for setting up an RDS, which is the most important step to get replication started. Data is replicated from a Primary node, where the application is running, to one or more Secondary nodes. The primary node and the secondary node could be present in an on-premises or a cloud data center. An RVG on the Primary node, and the corresponding RVG on the Secondary nodes, make up an RDS. Volume Replicator uses the Replicator Log to keep track of pending writes.
You must first set up an RDS and start replication before you can perform any other Volume Replicator operations. After setting up an RDS you may want to perform other tasks such as monitoring the replication and changing configuration settings.
Note: If your deployment involves setting up replication in over cloud, then you must first set up the cloud infrastructure and then begin with the replication setup.
Most of the tasks that have been discussed in this chapter and in the following chapters can be performed using the VEA or from the command line interface.
Note: Within this document, any reference to a Secondary node implies all the Secondary nodes. Thus, for the operations that need to be performed on the Secondary, it is implied for all the Secondary hosts, unless otherwise specified.
