Automatic single file backup to File Store or SD/C

Hi there, first post to your forum, so please bare with me!
Hope youre doing ok!

Ok my problem that I need help on is.
I have a HX4700 with a Garmin CF620 Compact Flash GPSr unit.
This unit uses the Garmin QUE software for navigational purposes.
The active track-log is saved in a single file in the installation directory (program files) and on two occasions I've lost the tracklog and almost got myself in an emergancy situation due to either a battery issue or the nessesety to do a hard reset.

My question is if you perhaps know of a 3rd party software that I can use to either in real-time or given time intervals mirror / sync the file to the Ipaq file store or external memory .

I'll even be happy if its a program that I have to run to copy the file to another location, then I can at least assign it to a butten, and press it every so often.

I will really appreciate it if you could help me as I ofter travel remote areas (no roads), use the data to help develop electronic maps and navigation tools for other african travellers.

Thanx in advance.
