    Before start copying, <br>
    - Enable changelog in Master volume, using `gluster volume set
    &lt;volname&gt; changelog.changelog on`<br>
    - Record the Timestamp. This is required to set the marking once
    Geo-rep session is created.<br>
    - Gluster Geo-replication replicates the data with same GFID in
    target, so if we are copying data manually we should ensure that
    GFIDs remains same and properly linked as hardlinks in the
    .glusterfs directory.

    After creating the Geo-replication session it will try to start from
    the beginning, to avoid that set the marking in each bricks before
    starting Geo-replication saying till this time data is synced to
    Slave. Once started, it will start from this timestamp.(I can
    provide script for the same)
