# bluraybackup(1)

Tool to backup Blu-ray Disc Movies (BDMV)

## NAME

bluraybackup - Tool to backup Blu-ray Disc Movies (BDMV)

## SYNOPSIS

**bluraybackup** \[-d *device*\] \[-k *keyfile*\] \[*FILE*\] \[*DEST*\]

**bluraybackup** \[-d *device*\] \[-k *keyfile*\] -m \[*DEST*\]

**bluraybackup** \[*OPTION*\]

## DESCRIPTION

**bluraybackup** backups Blu-ray Disc Movies (BDMV), inspired by dvdbackup, developed in ANSI C (C89) following the suckless philosophy.

It makes a decrypted copy of the whole Blu-ray Disc Movie or it extracts a decrypted version of a specific BDMV stream.

This program may not work with all Blu-rays. It both depends on your KEYDB.cfg file and on the BD+ generation (version).

To successfully decrypt a Blu-ray Disc Movie you both need libaacs installed and a KEYDB.cfg file, containing your disc keys.

Moreover, if your disc is plagued by BD+ as well, you need to install libbdplus. BD+ is a form of copy obstruction, which consists in writing video streams to disc with small errors. These errors get fixed during playback by a virtual machine embedded in official players, only if the player keys are verified by the same virtual machine. libbdplus is an implementation of the BD+ virtual machine features. However it doesn't support all the BD+ generations. Since libbdplus 0.2.0, it's possible to bypass BD+ emulation, using cached tables to fix the broken streams.

## OPTIONS

- **-d**, **--device** *device*

  defines Blu-ray disc device (default /dev/sr0)

- **-h**, **--help**

  print usage message

- **-k**, **--keydb** *keyfile*

  defines keys database file path (default $HOME/.config/aacs/KEYDB.cfg)

- **-m**, **--main**

  copy main Blu-ray disc title (see USAGE)

- **-v**, **--version**

  print version and license information

## USAGE

**bluraybackup** \[-d *device*\] \[-k *keyfile*\] \[*FILE*\] \[*DEST*\]

Without *FILE*, the whole disc will be copied to the current directory. *FILE* must be a file path relative to the disc root.

Without *DEST*, the decrypted *FILE* will be sent to standard output. *DEST* path must include file name.

**bluraybackup** \[-d *device*\] \[-k *keyfile*\] -m \[*DEST*\]

Without *DEST*, the main disc title will be sent to standard output. *DEST* path must include file name.

## EXIT VALUES

- **0** - Successful copy

  - **1** - Everything else
