About incremental synchronization
An incremental synchronization targets to synchronize only that data which has changed since the last synchronization (either incremental or full synchronization). Incremental synchronization saves much of the time and resources used in replication of the data between the data centers.
Except the two conditions where a full synchronization is performed in Veritas Resiliency Platform (after disaster recovery configuration and after a recover operation), at all other times, Resiliency Platform uses incremental synchronization while replicating the data from source data center to target data center. These instances where incremental synchronization is used in Resiliency Platform include the following:
If there are any network failures in the replication path
If there is a system reboot of Replication Gateway or protected virtual machines
If you replace a healthy or faulted Replication Gateway with another Replication Gateway
If you perform a migrate operation. In this case, the virtual machines are brought up on the target site and then direction of replication changes. At this point, Resiliency Platform uses incremental synchronization.
If the replication state is Syncing, you can view the status of data replication on the resiliency group details page. The progress is displayed on a status bar with percentage complete information. Time required to sync the data is also displayed on this page.
