Backup Options

July 17, 2019

You can enable more advanced settings for your backup task via Backup Options, for example, you can compress your image file, split large image file into small one, etc.

You can find the "Menu" option (three-line on the upper right side of the main window) and "Backup Options” in the Backup page for the specific backup task. In “Menu”-->“Settings ", it is possible to individually customize the global parameters when backing up data, including the compression level, splitting image, notifications settings, intelligent sector, VSS, etc. In“Backup Options", it is possible to set parameters for the separate task, including the compression level, backup encryption, notification enabling, splitting image, intelligent sector, VSS, other.

Advanced settings for your current backup task

When creating a new backup task, you will see "Options" in the lower left corner of the interface.

Add Disk

Click it and you will see "General", "Backup Mode", "Command" and "Advanced" options.


In this option, you can write a note for your task to help you distinguish it from other backup tasks, meanwhile, you can enable encryption and email notification for this task.


Email Notification: In unattended operations, a notification can be emailed containing the result of each backup.


Notification Settings: You can choose the one you need from the following options.

1. The operation is completed successfully.

2. The operation fails.

3. User interaction is required.

Notification emails can be sent using HTML or text. All conditions for sending email notifications are selected in the Notification Settings by default. A report will be provided if the operation is completed or not. For verifying settings are correct, AOMEI Backupper has the option to send the test message to the configured email address or phone number if “Send for test” is selected.

To Enable Email notifications for a Backup Task

1. When creating a new backup task, you can enable email notification through "Backup Options"---"General"---"Enable email notification".

2. You can enable email notification for an existing backup task in the Home screen by selecting the “Advanced" task, followed by selecting “Edit Backup” and then tick“Enable email notification".


  • When you set email notification with the Custom server selected, AOMEI Backupper requires SMTP authentication and it does not support anonymous access.

  • When you set up email notification with Gmail server selected, sending the test email notification may fail. As far as we know, it is caused by Google that has enhanced the security level of Gmail so you need to turn on access for the less secure app in Google settings first. After that, you can retry it.

  • AOMEI Backupper cannot configure multiple email addresses to receive the email notification. You can create an email group and add these email addresses to this group. After that, you can put the group email address as the receiver of notification, so these email addressed under the group can also receive the email notifications.

Backup Mode

In this option, you can choose the backup and VSS mode.

Backup Mode

Intelligent Sector: For intelligent sector feature, Aomei Backupper use intelligent sector way by default and if you select sector by sector way, backup time would be longer as it will back up used and unused space of your disk. This feature is set for System Backup, Partition Backup, and Disk Backup only.

Intelligent Sector

VSS: VSS (Volume Shadow Copy Service) is a backup technique of Microsoft, which allows the computer to continue to be used while a backup is in progress. If VSS is not used, then Backupper will automatically use its own built-in technique instead of performing a live backup. Choose one of the modes to begin the backup task.



In this option, you can set the pre-command and post-command.


Pre-command: Run the specified program or script before backup or synchronization.

Post-command: Run the specified program or script after backup or synchronization.

Configure User Command

Command: Browse to load a script file or executable program file.

Working directory: Type into a path to save the result of the Pre-command or Post-command execution.

Arguments: Set some arguments for the command if necessary.

"Terminate the operation if the command fails to execute" and "Do not perform the operation until the command execution is complete" are selected by default.

Click "Test" button to verify the command.

Click "OK" button to save the command settings.


1. Real-time sync doesn’t support Pre-command and Post-command.

2. Generally, the source path of the script file or executable program file will be filled into Working directory by default after you add the script file or executable program file to Command. You can change to other path manually.


In this option, you can change the compression and spliting level.

Compression: You can choose the compression level for your backup task. If you choose high one, then it would take a longer time to create the backup.


Tip: Some computer files(such as .jpg, .pdf or .mp3) are already compressed. If the backup image file contains many such files, then the generated backup file may not significantly decrease in size even though the high compression lever is selected.

Splitting: Backup files can be split into several smaller files to fit into different smaller storage media. Backupper can automatically create a backup file into multiple parts during the backup process. The options available are listed below.

Automatic: The image split size depends on the file system of the destination storage medium. For example, FAT32 partition only can save files less than 4GB.

Customize size: Input the required file size value and future backup images will be split into segments of this size. The minimum supported file size is 50MB.

Choose a predetermined size: Choose the storage medium type in the drop-down menu. AOMEI Backupper will then split the image file to suit the selected medium.

Automatically create a folder with the same name as the task in the target location: It is ticked by default. So, it will create a folder with the task name under the target path to save backup files or synced content. For example, you create a backup task named as Disk Backup, it will first create a Disk Backup folder under the target drive you select and save backup images to here.


You will find more options in Menu-->Settings-->Advanced:

Advanced Other Settings

Automatically check the backup on completion: AOMEI Backupper will check each backup upon completion automatically to verify the backup has been created properly.

Don't show tray icon next time: Generally, the scheduled task will show via a tray in the lower right corner of the computer when task is performing. If you check the option, the tray icon won't appear when the scheduled task is performing automatically.
