How do snapshots work when using replication?

The snapshot function enables the system administrator to freeze the data content of the volume at a certain time. From this moment on, the users work on a virtual data volume and all changes to the volume are stored in a different partition.


We have two kinds replication: volume replication and data replication.


Volume replication replicates the whole volume synchronously, (i.e., once started, it is running and copying new data all the time).  However please note that it is limited to 4TB.


Data replication can be used to replicate particular shares asynchronously,  (i.e., it is active when the task starts and it stops after all files are copied).  It does not have a capacity limit.


NOTE: Destination and source volumes need to be of exactly the same size in order to successfully perform the replication.  Replication works only between two mirror replication servers.  In other words, the mirror server address of the source is that of the destination server, and vice-versa.
