With this crawling is not required to detect the modified/created files after last sync. Once the changes are detected it calls Rsync command with predefined list of files.(--files-from argument of rsync). Rsync will take care of syncing only delta changes to target Volume. Let us know if you have more queries about Geo-replication.> > > thx lot > > > _______________________________________________ > Gluster-users mailing list > Gluster-users at gluster.org > http://lists.gluster.org/mailman/listinfo/gluster-users-- regards Aravinda VK http://aravindavk.in -------------- next part -------------- An HTML attachment was scrubbed...
