Editor to share with you the use of linux e2image command to save ext2/ext3 file metadata, I hope you will learn a lot after reading this article, let's discuss it together!

The e2image command can save a "ext2" or "ext3" file system in a dangerous state to a file. The generated file can be used by the dumpe2fs command and the debugfs command through the "- I" parameter. Experienced administrators can use it for file system disaster recovery.

To save disk space, e2Image creates image files as sparse files or in QCOW2 format. Therefore, if you need to copy a sparse image file to another location, you should compress it first, or use the GNU version of the cp "sparse=always" option. This does not apply to QCOW2 images, which are not sparse.

Syntax format: e2image [parameters] [file / file system]

Common parameters:

Reference example

Generate a defined partition metadata image file:

[root@linuxcool ~] # e2image / dev/sda1 sda1e2image 1.44.3 (10-July-2018)

View the system type of the file:

[root@linuxcool ~] # file sda1sda1:Linux rev 1.0 ext2 filesystem data

Generate an QCOW2 image file:

[root@linuxcool] # e2image-Q / dev/hda1 hda1.qcow2

Generate an original image file:

[root@linuxcool ~] # e2image-r / dev/hda1 | bzip2 > hda1.e2i.bz2 has finished reading this article.
