Combine incremental images
If you have already created several incremental images, you can combine them to form a new base image. The newly
created base image is now a "complete" image. Older images that contained only changes can be deleted once the
combining has been completed.
1. Make sure your computer will be able to access all drives where the base and incremental images are located.
2. In the menu bar under Tools click Merge incremental images.
3. A program window will appear where you can select and merge the existing image files.
Note: Only consecutive image files (Image of the changes) with the same base image may be merged. By clicking
Image information and the corresponding Drive information you will find all details about the image(s).
Check image file for errors
Under Tools is a function called Check image file for errors. This function checks the structural integrity of an image
file. It determines whether the logical structure is intact. Damage can be caused by virus attacks or defective hardware.
In addition, encrypted and/or compressed images will be checked to determine if decryption or decompression is
possible without error.
Reasons for an abortive validation:
• Encryption and decryption are not functioning
• Compression and decompression are not functioning (Windows API/System interfaces)
• The user has changed the image file
• Image has been changed by a program driver (e.g. anti-virus software)
• Image is stored on a defective volume
Note: To make sure your image is created or restored without error, keep the validation process running until the
imaging or restoration is completed. If you choose to “Skip” or “Abort”, there’s no guarantee that your image will be
created or restored intact.
