Simply create a symbolic link to the archive directory in the http root directory, which is normally just used for map images.
In the terminal (linux, not the game terminal), type:
ln -s /mnt/sda1/minecraft/archive /var/www/httpdocs/archive
Change the first minecraft archive directory to match your own (it may be a different drive, or different if you're using a ramdisk).
Now browse to your server IP (without port 8080), and the archive directory will be listed along with the snapshots directory. Download to your hearts content!
You can do the same for your incremental backup directory if you so desire.
EDIT: You may or may not need to edit /opt/.filetool.lst to include the /var/www/httpdocs directory (and then a sudo filetool.sh -:cool.gif: so changes there are saved in the httpdocs directory upon reboot. I did that early on and have never tried without it so I don't know if it's necessary or not. :smile.gif: Can someone make the symbolic link without editing .filetool.lst, reboot, and see if the link sticks?
