I have put together a short program, imaginatively named 'Route_Backup' which has the ability to back-up a selected route by either double clicking a desktop icon, or preferably by adding the backup program to the Windows Task Scheduler and it will then automatically back up your route to a dated folder at set intervals, daily, weekly etc as you wish.
With this you should no longer have any excuse for using days of work
See http://www.rstools.info/Route_Backup.pdf for full details.
