bluraybackup is a command-line program inspired by dvdbackup [1], developed in C99 following the suckless philosophy [2]. I wrote it because I wanted to have a 1:1 copy of my Blu-ray discs or the ability to save an unencrypted version of a BDMV stream. Since Blu-ray is an especially nasty format [3], this software does not work with all Blu-ray discs. It both depends on your KEYDB.cfg file and on the disc BD+ generation. I don't know what the hell BD+ is! Don't count on your copies being perfect, if you see libbluray errors during the operation. You have been warned. This software is based on libbluray [4]. To build it you need libbluray and its headers.
