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:
v1.1.3
- bash completion
- add experimental debian package build scripts to Makefile
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)
