bakudf

bakudf is a simple script that helps create udf file systems for backing up or archiving data, e.g., on blu-ray discs.

Usage

bakudf.sh creates udf file systems, optional md5 checksums, and prints out instructional text for the next steps:

bakudf - udf backup helper script

Usage:
    ./bakudf.sh <create> <project> <size>
    ./bakudf.sh <md5> <project> [create|verify]
    ./bakudf.sh <finalize> <project>
Arguments:
    create:   create a new project
    md5:      create (default) or verify md5 checksums for a project
    finalize: finalize a project
    project:  name of the new project
    size:     expected size of the project, e.g., 25GB, 5GB

First steps:
* Create a new project with
  ./bakudf.sh create <project> <size>

bakudf performs the following steps:

• create: bakudf creates an udf file system named <project>.udf with the size <size> and mounts it to a subdirectory called <project>. Then, you can copy all files you want to backup into that folder.
• md5: Optionally, bakudf creates md5 checksums of all files in your project folder <project> and writes them to a file called <project>.md5. You can put this file into the udf file and write it to disc. Thus, you can verify later if the files on the disc are uncorrupted.
• finalize: Finally, bakudf unmounts the project folder, so you can write the udf file to disc.
