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
