Copy all files using file:// protocol in Camel on Fuse ESB 7.1 even those which were copied a minute ago

Issue

We are trying to implement Scheduled File transfer in Camel using the CronScheduledRoutePolicy. Our requirements are:
1. Copy all files from one directory to another every minute
2. Don’t remove any files from the source
3. All files must be copied – even those which were copied a minute ago
Below is how we implemented this in Camel (version 2.10.0.fuse-71-047), however it doesn’t copy the files which were copied a minute ago. It looks like even if the route is stopped before being started, it still remembers which files were already copied.
