Synology Active Backup for Business Recovery Wizard
Active Backup for Business supports bare-metal and volume-level backup and restoration through a preconfigured recovery media. This article will explain how the recovery media works when restoring the entire machine or specific volumes with a specific backed up version stored on Synology NAS. For more information on how to configure the recovery media, please refer to Recovery Media Creation Guide.

- Network adapter:
Please click List of hardware drivers to check if the required network adapter has been installed, or click Internet Settings to fix the problem when failing to connect to the Internet by default. Recovery cannot be performed without network connection. In most cases, the Internet should be automatically supported if the WinPE applied by the recovery media is for Windows 10.
- Load drivers:
Please click List of hardware drivers in the context menu
and click Load Drivers to install the target driver when needed. It is suggested to load and install all the necessary drivers in advance.
