e2image

Save critical ext2/ext3/ext4 filesystem metadata to a file. More information: https://manned.org/e2image.

• Write metadata located on device to a specific file:
  e2image {{/dev/sdXN}} {{path/to/image_file}}
• Print metadata located on device to stdout:
  e2image {{/dev/sdXN}} -
• Restore the filesystem metadata back to the device:
  e2image -I {{/dev/sdXN}} {{path/to/image_file}}
• Create a large raw sparse file with metadata at proper offsets:
  e2image -r {{/dev/sdXN}} {{path/to/image_file}}
• Create a QCOW2 image file instead of a normal or raw image file:
  e2image -Q {{/dev/sdXN}} {{path/to/image_file}}
