  • generating a snapshot of the client data set on a local volume, wherein the client computer uses a file storage format;

    synchronizing with a remote server volume corresponding to the local volume to create a copy of the client data set on the remote server, wherein the remote server accepts heterogeneous format;

    performing a master to slave replication of the data set;

    reading an existing snapshot history and making a snapshot mirror on the remote server by starting with an old client snapshot, syncing the snapshot, selecting another snapshot and syncing the snapshot and for each syncing, taking a corresponding server snapshot;

    creating series of snapshots on the remote server to mirror the snapshots on either the client computer or the appliance; and

    transferring back-up data files using a client software on the computer, wherein the client software receives inputs from a web user portal to control operations of the client software and a system management platform to back up the customer computer with one or more data storage silos, each including a plurality of storage directors communicating with the client software; and
