HD Install :: Ramdisk writing back to HD

I just installed DSL to a CF card via Frugal Install. During the installation process I selected LILO and the 'toram' option. I know that the ramdisk is backed up to the HD on shutdown/reboot, I was wondering if there was a way to perform this same backup while the system is live? For instance if I were to use DSL as a miniature server, is there a way I could back everything up to the CF using a cron job?

The ramdisk is *not* backed up on shutdown/reboot. Only select files are backed up.

Probably the easiest thing would be to automate /usr/sbin/filetool.sh to run at intervals, although cron is not in DSL so you may need to use "sleep" in a loop in a shell script.

If you want to use cron, it is available in mydsl.

Thanks for the help guys. It's greatly appreciated.
