To create an incremental image, you must have first created a complete image of the respective drive. As a base
image you can use either a "complete" image, using the methods "Used sector imaging", "Forensic imaging" or
"Direct forensic imaging", or by using a previously created incremental image/differential image.
Follow the instructions below:
Please make sure that the drive containing the base image is connected to your computer.
On the O&O DiskImage start page, click Differential/incremental imaging.
Select your base image in the browser window and click Open.
Now you can either select the recommended drive for saving the image, or enter a new target path. For
greater clarity, it's advisable to store the base image and its respective incremental/differential image file on
the same drive. You may, however, use any drive you wish.
5. The image is automatically named after the creation date. You can however enter a name manually.
6. Now click Start to create a differential/incremental image from the base image. The Imaging method of the
original "complete" image, e.g. Used sector imaging, remains the same and cannot be amended.
Note: the option Compare data with checksums is set as default. While creating incremental images, it is suf-
ficient to use the last incremental image as base image. Should Use checksums to administer unchanged data
not be set, you will need the last base image and all the incremental images previously created, since all of them
will be accessed for creating the new image.
If you want to restore one or more drives from an existing image, click Restore drives on the O&O DiskImage start
page. O&O DiskImage, by default, will always go the place where the last image was saved. If the image file pre-
sented is not the one you want, browse through your drives and enter the path to the image file.
Select the image file (*.omg) or (*.vhd) in the dialog window and then click Open.
All drives contained in the image will then be displayed.
Click the drive that you want to restore ("play back").
In the following dialog, select the target drive for restoration by clicking next to it. You can either replace an
existing drive or create a new one: for example, in an empty sector.
5. Click Map if you want to continue with restoration or select additional drives from the image.
6. In the following dialog under Further options, you can specify whether certain functions should be executed
when restoration is completed. These functions are disabled by default.
7. Once you've enabled all the settings, click Start to begin the restoration process.
Important: During restoration, the image overwrites your selected drive with the data of the drive contained
within the image. All data saved on the target drive is thereby lost and replaced by that of the image.Note: You can learn more about restoration in the chapters Advanced restoration and Settings for restoration
on different hardware. (Page 52 in this pdf document)
