v1.1.2
7aa5754

Generate paper backups for Linux. Currently command-line Linux only.

qr-backup takes file(s), and outputs a "paper backup": a printable black-and-white pdf full of QR codes. To back up your file, print the PDF. The pile of paper in your hand is now a backup of the file.

If your file is lost, corrupted, deleted, etc, you can restore from your paper backup. qr-backup reads the QR barcodes using your computer's webcam (or scanner) to get your file back.

Major new features:

v1.1.2

  • qr-backup is ready for packaging

v1.1

  • Add --restore option, which automatically does a restore in qr-backup itself. Previously restore was done with a bash oneliner only (which still works). Note that --restore cannot restore backups made with v1.0.
  • An automatic digital restore check is done after every backup.
  • Allow restore (using qr-backup only) even if up to 30% of barcodes are missing. Uses reed-solomon erasure codes.
  • Improved data density, but this roughly cancels out with increased size from erasure coding.
  • Optional password protection (encryption).
  • Support backing up a directory. Support backing up multiple files or directories
  • Support printing multiple copies of each barcode
  • Customize printed documentation (less, more, custom notes)
