Gluster Geo-replication uses Changelogs to detect the changes happened 
in the Volume. 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.
