+# 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}}`
