In geodatabase editing, the portion of the data in a geodatabase that is copied from a source geodatabase to a destination geodatabase during the replication process. The replica includes information needed to synchronize changes to the data. There are three types of replicas: one-way replicas, two-way replicas, and checkout/check-in replicas.
In ArcGIS software, replicas are managed using Replica Manager. With this utility, properties of each replica can be renamed, refreshed and reviewed, and datasets can be removed from a replica. All replicas may be viewed with a role of parent or child; list only checkout/check-in, one-way, two-way, or all types of replicas; and the replica log may also be viewed. This utility is available in both ArcCatalog and ArcMap.
