# e2image
> Save critical ext2/ext3/ext4 filesystem metadata to a file.
> More information: <https://linux.die.net/man/8/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}}`
