Let me ask this question a different way:<br>

Can someone please give me an overview of<br>
the geo-replication architecture.<br></blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><br>
Is there some process that is called every x<br>

According to the docs, the geo replication is<br>
asynchronous. I assume that means it is not real-time.<br>
<br>
How much of a delay should I expect for files to be<br>
replicated across a network?<br></div></div></blockquote><div><br></div><div>The delay by which is you can expect the files to be synced at the other end depends many factors such as the Network bandwidth, the time rsync takes to sync them (if it's a new file the whole file sent across the network, if it is just an edit, then only portions of it would be sent across network).</div>
