How to use DiskGenius - Backup Partition to Image File and Restore

---Backup Partition & Restore Partition

The function of "Backup Partition To Image File" can backup all available data of a partition include all files in it to a single file or a group of files called "Image File". The partition will be cloned to the image file. So this operation is also called "Clone Partition To Image File".  When the partition is damaged for some reason, it can be restored from the image file(s). And also, in some cases, you can restore the image file to an other partition.

1. Backup Partition.

To start a partition backup process, click the "backup" button on the toolbar, or select the menu "Tools" - "Clone Partition to Image File",  DiskGenius will popup the following "Backup Partition" dialogbox:   

Click " Source partition" button to select a partition you want to backup now, DiskGenius will popup the following "Partition Select" dialog:

Click "Select Image File" button to open the "Open File" dialog and select the target image file.

To save disk space, you can select to compress the image file. There are 4 compress options can be selected, "No compress", "Fast compress", "Normal compress" and "High quality compress". Compress image file may take more time according to which compress mode you select. The higher compress quality, the slower of the partition backup speed will be, and of course the image file will smaller. If no special requirement, "Fast Compress" is suggested.

Before starting the clone partition process, you can enter a remark no more than 800 bytes.

Click the "Start" button to start the partition backup process. The following warning message box will popup:

Close all related programs and then click "OK" button. DiskGenius will try to lock the source partition. If it failed on locking the partition, the following warning message box will be displayed:

The process of clone partition to image file may successfully completed while the source partition is not locked. But the data of the files which are changing by other programs during the partition backup process can only be backup to a certain time point. Click "Yes" to start the backup partition process. The following picture shows the backup progress:  

2.Restore Partition

When the partition was destroyed, or in other case there is something wrong with the partition, the full partition can be restored from the image file that previously backuped. The restored partition will be same as it was before back up. Click "Tools" - "Restore Partition From Image File" menu item, DIskGenius will show the following dialogbox:

Click the "Select Image File" button to select the partition image file. And then click "Target Partition" button to choose the partition which you want to restore. When an Image file is selected, the related information of the partition image file will be displayed. If the image file and the target partition were correctly selected, click the "start" button to prepare for restoring the partition. DiskGenius will show the following warning message box:

Click "OK" if anything is ok. DiskGenius will start the restoration process.

When the partition is restored completely, the partition and all its files will be restored to the time point which the partition was backuped.
