Abstract: Systems and methods are disclosed for state consistent replication of client data set on a client computer by generating a snapshot of the client data set on a local volume; synchronizing with a remote server volume corresponding to the local volume to create a copy of the client data set on the remote server; performing a master to slave replication of the data set; and taking a snapshot of the server data set to create a mirror of the snapshot of the client data set on the server.
