When SyncIQ replicates data, it goes through one of three phases. The three phases are Initial, Incremental, and Differential. This section explains each phase.
Note: This section provides a detailed explanation of the SyncIQ data replication process. Many of the details in this section may not be necessary for implementing and managing SyncIQ. Understanding all the steps in this section is not required. However, the details in this section are provided for a granular understanding of how SyncIQ data replication occurs, enabling a foundation of the concepts explained throughout this paper.
