With Nero BackItUp ImageTool you can make a drive backup and write it to a disc.  
The following assumes that the backup is written to several discs.
In order to write a drive backup to a disc, proceed as follows:
1.
Click the Backup > Drive Backup button.
à
The Manual drive backup screen is displayed.
2.
Select the appropriate check box to select the desired hard drive or partition.
à
The hard drive or partition is selected.

 

 
 
You can select several partitions in a hard drive for a backup. However, only one hard drive can be selected per pass.
 
 
3.
Click the Next button.
à
The Select target and options screen is displayed.
4.
Select a burner in the Target drop-down menu.
5.
Make additional settings as desired.
6.
Click the Next button.
à
The Finalize screen is displayed.
7.
Verify the settings in this screen.
8.
Click the Backup button.
à
The Backup Process screen is displayed and the backup process starts. You can track the process with the progress bar.
à
The Waiting for Disc window is opened, and the selected drive is ejected.
9.
Insert a suitable recordable disc.
à
The Waiting for Disc window is closed and the backup process continues. (Nero BackItUp ImageTool starts a multisession disc automatically or continues with it.)
à
If the disc’s storage capacity is exhausted, the Waiting for Disc window is opened again and the disc is ejected.
10.
Remove the recorded disc and insert a new blank disc.
à
The backup process resumes and the newly inserted blank disc is burned.
11.
Repeat the previous step until the backup has been completely burned to disc.
à
Once the backup is complete, the disc is ejected and the Backup Process window is opened.
After the backup has been written completely, Nero BackItUp ImageTool will want to verify the data by default. For this purpose, it will require the discs in the sequence that they were written.

 

 
 
If the backup was written to one single disc, the verification process is started automatically.
 
 
12.
Remove the disc.
13.
Click on the Disc drives button in the Backup Process window.
14.
Insert the first disc of the backup in order to have it verified.
15.
Double-click the drive containing the disc.
à
The verification process is started and the first disc verified. The disc is then ejected and the Backup Process window is opened again.
16.
Repeat the two previous steps for each disc of the backup in chronological order.
à
When the backup is completed, a window with an appropriate message is opened.
17.
Click the OK button.
è
You have written the drive backup to a disc. Now you can save the log or click the Next button to start other actions.
