Creating a Snapshot Mirror (Ad Hoc Sync Job)
Creates a Snapshot Mirror. In synchronous replication, takes a snapshot of the
source peer (Master) and the target peer (Slave) at exactly the same time. In
asynchronous replication, the command establishes a process that takes a
point-in-time snapshot of the source peer (Master) and synchronizes that
point-in-time with the Slave. The process will set a new sync-job to copy the
differences between that snapshot and the most recent snapshot that is guaranteed
to be synchronized with the target peer.
