Downloading _big_ files: problem, and solution.

I have started downloading the .iso file for burning an OS DVD.

Problem: 

- The file is _BIG_ (3.4 GB) and the download takes around six days.

- The power supply here in Paraguay does not last that long without power 
cuts, specially at this time of the year.

-When the UPS battery runs out the computer shuts down in an orderly manner, 
closing all the progs that are running at the time.

-And when you close down Konqueror in the middle of a download it deletes the 
xxx.iso.part file.

This already happened to me twice, each time around 1.2 GB or 30% of the 
download; 
AAAAAAAAARGH !  (feel better already  ;-3)

Solution:

A cron job that will, every hour:  cp -f xxx.iso.part xxx.iso.part.bak

That way at the worst I now only loose one hour's worth of download, as I can 
cp xxx.iso.part.bak xxx.iso.part and resume the download.
 
YMMV

Cheers,
 
Ron.

             It's easy to criticize, but if everybody hated you,
                            you'd be paranoid too.
