I'm pretty sure it's file versioning, but I'll get one of the devs to fill out a feature template to provide more explanation.<span class="HOEnZb"><font color="#888888"><br><br>-JM</font></span><div class="im">

Can someone explain to me what is meant by that? Is there a wiki page for the proposal?<br>
<br>><br>We are seeking a type of versioning functionality like a <a href="http://en.wikipedia.org/wiki/Versioning_file_system" target="_blank">multi version filesystem</a>, where a translator writes the previous version of a file out to some location (other brick) when the file is about to change. This is because we have a very low change rate, but need to keep the old version available for a long time if a change does happen. Files do get moved around in directory structures, but almost never changed.<br>
<br></div></blockquote></div><br><br>I added a note on roadmap page. Versioning idea started out of "Continuous Data Protection" requirement. Originally we thought we will implement versionng similar to geo-rep feature, where the remote volume holds change sets (like continuous rdiff-backup). Now I am leaning towards git based versioning. Integrate git into GlusterFS to track changes on specified events (timer, file-close, dir-tree-modify..). We may not do this via translator interface, but through the newly proposed simple event/timer interface. <div>
