For more advanced use AOMEI Backupper can be controlled from the Command Line, instead of using the Windows
interface.

Command Line Syntax

1. Run the command line prompt as administrator. To open the Command prompt, either:
a) Click Start, right
click Command Prompt and select “Run as Administrator”
Or
b) Press WIN+R to open “Run”
window and type “cmd” to open it.

2. Navigate to the of AOMEI Backupper installation directory by typing in:
cd C:Program FilesAOMEI
Backupper. If you installed the program in a different location, enter that location instead
This means open
the path–“C:Program FilesAOMEI Backupper” which is the installation directory of AOMEI Backupper of your
version. Note: the path must match the installation directory of the program you installed.

3. The options below specify all the Command line parameters that can be used to constitute a fully functional
command, e.g:
AMBackup.exe /b new /t disk /s 0 /d “d:disk” /n “Backup Disk0”
This commands AMBackup.exeto start a new disk backup and backup disk 0, next save the backup file to “D:disk backup” and name the backup
file as “Backup Disk0”

Syntax:

{} are the required parameters
[] are the optional parameters

backup version corresponding to the current image file will be restored without this “/v”
command.

[/I] {0 | 0:0}|[null]

specify the source , which means the disk, partition or dynamic volume to be restored in the image
file . /i 0 means disk 0 or dynamic volume 0;/ i 0:0 means partition 0 on disk 0; “null” means no
need to specify the partition to be restored while performing system restore.

[/e]{“123”}

specify the password for the image file

[/d]{0|0:0|D}|[null]

specify the destination location to restore to. “/d 0” means destination location is disk 0; /d 0:0
means the destination location is partition 0 on disk 0; /d D means the destination location is
partition D; “null” means not to use “/d”, and restore to the original location.

[/f] {fill | original}

adjust the size of the destination partition. “fill” means to fill the entire destination partition

[/k]

specify sector by sector restore. Only when the image file was backed up sector by sector, can it be
restored using sector by sector restore

[/o] {yes | no}

switch off the interactive prompt.”yes” means to execute automatically the next operation when
interactive operation is needed; “no” means to cancel the operation when interactive operation is
needed. By default, the program will wait for user’s confirmation.

Command for List Device

To list the devices, the required parameters are:

Parameters

2. list all the partitions
on disk 0 of the current system
AMBackup /l 0

3. list the content of the backup image named
backup.adi. If the image is a system, partition or dynamic volume backup,the partition(s) backed up will be
displayed; if the image is a disk backup, the disk(s) backed up will be displayed.
AMBackup /l /s
D:backupbackup.adi

4. list all the partitions on disk 0 of the disk backup named disk backup.adi

AMBackup /l 0 /s D:disk backupdisk backup.adi

Notes:

  • You cannot back up data to disc (CD/DVD) by using the command line. If you want to back up data to
    disc, please use AOMEI Backupper GUI.

  • When you back up the dynamic volume(s) with no drive letter(s), then you need to assign drive letter
    first.

  • If your partition has no drive letter, you can use its partition number on the disk to specify it. For example, the partition is the second on the first disk, then you can use “1:2” to replace the drive letter. You can find the numbers of disks and partitions byusing the command “AMBACCKUP /L”.

  • The AOMEI Backupper command line program must be run with administrator privileges. If you are a
    non-administrator user, a window will pop up in which you need to enter the correct account
    information to finish the backup process.

  • When you back up data to a NAS, you must provide a valid IP address, such as
    “\192.168.0.10foldername” to identify the network path.

  • The command line implementation of AOMEI does not support file level backup operations.
