AOMEI Backupper lets you clone the partition or disk, too. The software already supports the Microsoft Volume Shadow Copy Service (VSS) that enables the data backup process and does not interfere the running applications. This option of AOMEI Backupper is very efficient because backup data can still be made when you’re working.
To prevent data loss, so we need to make data backup, AOMEI Backupper with the following features to ensure the safety of your data.

System Backup. One-click back up all data of system drive, including system files and installed applications without interrupting system run.

In addition to backup and restore functions, AOMEI Backupper supports cloning operations. If you need to upgrade hard drive, or replace old disk, or migrate hard drive to new one, this feature can be more convenient to your work.

Disk Clone: Directly copy one hard drive to another without creating an image file. The program allows you to resize partitions during this cloning process, and supports to clone small disk to larger disk as well as copy traditional hard drive to solid state drive.
Partition and Volume Clone: Directly create an exact duplication of partition or dynamic volume and exactly transfer it to another partition or volume.

AOMEI Backupper Other Features:
Incremental and differential backups. Based on a full backup, the software supports to create incremental or differential backups to taking less time and save storage space.
Encryption and Compression. You can set a password for each backups to prevent unauthorized access. When the backup process, specify an industry leading compression algorithm to compress image file in order to take up less disk space.
Image file checker and explorer. Check data integrity of image file to ensure the backups can be restored successfully. Mount image files to a virtual partition so that you can browse the contents of the backups in Windows Explorer.
Comment Backups and Splitting Backups. Add comments to backups so that the backups can be further identified and clarified. Let you know what a backup is for or what it contains. Splitting Backups can split backup an image file into proper sizes to fit storage media.
Create Bootable Rescue Media. You can create a bootable media (e.g. CD or USB media) to restore system drive on the condition that Windows can not boot.
Supported OS: Windows XP, Vista, Windows 7, Windows 8/8.1, Windows 10 (32-bit, 64-bit).
