You can use the pause feature of Volume Replicator to perform maintenance tasks, to backup Secondary data, and to change mode of replication.
Using the pause feature, you can do the following tasks:
To perform network maintenance tasks such as changing IP addresses on the Primary and Secondary host.
To stop using the network for some time to allow some other application to use it.
To backup the Secondary data which can be restored later, if required.
To change the mode of replication for a Secondary from the synchronous override mode to asynchronous mode when the network is slow, to avoid the writes from being stalled.
