PaperBack is an
application that allows you to back up your precious files on the ordinary paper in the form of the oversized bitmaps. If you have a good laser printer with the 600 dpi resolution, you can save up to 500,000 bytes of uncompressed data on the single A4/Letter sheet. Integrated packer allows for much better data density - up to 3,000,000+ (three megabytes) of C code per page.
The author asks why backup to paper, and correctly responds, that
by looking on CD or magnetic tape, you are not able to tell whether your data is readable or not. You must insert your medium into the drive (if you have one!) and try to read it.
PaperBack is free and is released under the GPL. More> ;-)
