# Disk Image Backup Guide

This is a walkthrough to help you create Disk Image backup.

* Disk Image backups will deduplicate with other data existing inside your Storage Vault. For example, backing up Files and Folders and performing a Disk Image backup from the same hard drive will deduplicate, and provide you with a valuable storage savings.
* If you are looking for technical information on the Disk Image backup type, please see this article: [Disk Image Backup](https://docs.eazybackup.com/documentation/disk-image-backup).

{% hint style="info" %}
After creating a Disk Image backup, if any changes are made to the partition table of the selected disk, the disk ID may change and eazyBackup will not recognize the disk. \
\
You will receive a warning that the drive can no longer be found and you will need to reselect the drive and/or partitions.

<mark style="color:orange;">**Advanced Option: Include unused disk sectors for forensic data recovery**</mark><mark style="background-color:blue;">**​**</mark>

By default unused space from the disk will be excluded from the backup, enabling this option will include any non-indexed and marked-as-deleted files in the free space. This could be used for forensic data recovery, but keep in mind that it will lengthen the backup time.
