1. Create compressed squashfs image

Use mksquashfs to create a compressed image from a directory. Depending on how compressible the files are you could put on much more than 4.7 GB on a single disc.

mksquashfs /path/to/my/directory image.sqfs

You can use a different compression algorithm with e.g. -comp zstd or append multiple times to one archive to fill it up to almost the allowable size.

2. Reencrypt the image to wrap it in a LUKS container
