<p style="margin-top:0px;margin-bottom:0px">I have a use case of having a remote office, which should be able to have a common storage area with a main office.</p>

<p style="margin-top:0px;margin-bottom:0px">I at first though Geo
Replication would be ideal for this use case, however further reading
says that it is suitable for making a slave only copy for disaster recovery. Ie. there is no 'two way' syncing of files. <br></p><p style="margin-top:0px;margin-bottom:0px">To make it a bit clearer, the concept is that the remote site might be in the USA, and the home site in Europe.</p><p style="margin-top:0px;margin-bottom:0px">Scientists at the remote site copy files for analysis to a local storage server.</p><p style="margin-top:0px;margin-bottom:0px">At the home site there should be a replica of the analysis files. At the home site there are HPC resources to run simulations or process the data somehow. Results files are written to a storage server and then should be replicated back to the remote site.<br></p><p style="margin-top:0px;margin-bottom:0px"><br></p><p style="margin-top:0px;margin-bottom:0px"><br>

<p style="margin-top:0px;margin-bottom:0px">Would anyone be able to comment on the New Style Geo Replication which has come along in Gluster version 4?</p>
<p style="margin-top:0px;margin-bottom:0px">What is the status please, and is it a suitable method for enabling a share at a remote office which syncs either way?</p>
