What Is Disk Backup?
Disk Backup is used to back up all partitions including the system partition and boot partition on the specific disk you select to an image file. That means if you back up a system disk via Disk Backup, after restoring it, the system can boot normally. However, Disk Backup is different from System Backup, because System Backup backs up partitions related to the system only (system partition, system reserved partition, etc).
How to Use AOMEI Backupper for Disk Backup?
AOMEI Backupper, the all-around disk backup software, can back up MBR disks, GPT disks, external hard drives, USB disks, and other storage devices. For regular backup, it provides users with the function of incremental and differential backup mode to improve the backup efficiency and reduce the storage space required by the generated image file.
You can do free disk backup with the free version of AOMEI Backupper - AOMEI Backupper Standard. Learn the detailed steps below. Before starting the operation, download, install and launch AOMEI Backupper.
To back up disk with AOMEI Backupper:
1. In the left tab page, select Backup and then select Disk Backup.
2. Click "Add Disk". Also, you can choose to name this backup using the "Task Name" field to help you distinguish it from other backups.
3. In the popup window, select the source disks that you want to back up and
you can add several disks to be backed up via Disk Backup in a single backup
Tips: Even though you can add several disks to be included in the backup, you need to restore these disks one by one. Moreover, it is impossible to restore several disks' included in an image file to one larger disk.
4. Click where the arrow point to select a destination path to store the image file.
5. Click the Start Backup button and wait for the process to complete.

When performing Disk Backup, AOMEI Backupper allows you to back up several disks each time, so you need to confirm that the destination must have sufficient space to contain the image file of all these disks. When performing the restore, you need to restore the corresponding disks one by one. Please note the more data to be backed up, the more time it will take.
For dynamic disk, Disk Backup is not supported in all versions and if you want to back up it, please use System Backup or Partition Backup.
AOMEI Backupper Standard version does not support any operations on the dynamic disks.
For encrypted disks, Backupper uses the sector by sector method to back up the disk by default.
If there are non-NTFS or FAT32 partitions on the disk, Backupper uses the sector by sector method to back up the partitions.
Backupper currently doesn't support backing up the disk with 4096 bytes/sector. But, you can save the image file to 4096 bytes/sector disks.
