<h2>Synology Active Backup for Business Recovery Wizard</h2>
<p><strong>Active Backup for Business</strong> 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 <a href='https://sy.to/abbrmenu' target='_blank'>Recovery Media Creation Guide</a>.</p>

<h3><a name="Recovery"></a>Synology Active Backup for Business Recovery Wizard: Recovery</h3>	
	
<h4>To restore a version from the server:</h4>

<p>After you have entered the BIOS menu and selected the boot order for booting recovery media, you will be directed to the welcome page of Synology Active Backup for Business Recovery Wizard. Once you have been directed to the welcome page, you can follow the steps below to start the recovery process: </p>
<ol>
<li><strong>Load drivers and network adapters</strong>:
	<p>This step is optional and is only required when you are using specific network adapters or drivers. Recovery may fail if the necessary driver has not been installed. To ensure a smoother recovery process, we strongly suggest you to double check the installed drivers and adapters in this step. </p>
	<ul><li><strong>Network adapter</strong>:</li>
	<p>Please click <strong>List of hardware drivers</strong> to check if the required network adapter has been installed, or click <strong>Internet Settings</strong> 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 is automatically supported if the WinPE applied by the recovery media is for Windows 10. In most cases, the Internet is automatically supported for Linux recovery media.</p>
	<li><strong>Load drivers</strong>:</li>
	<p>Please click <strong>List of hardware drivers</strong> in the context menu <img class="inline" src="../image/context menu.PNG" width="19" height="19" alt="" /> and click <strong>Load Drivers</strong> to install the target driver when needed. It is suggested to load and install all the necessary drivers in advance.</p>
	
	<p><span class="note_head">Note:</span> This method is not applicable for drivers that need to be rebooted to become effective. Please refer to <a href="https://docs.microsoft.com/en-us/windows-hardware/drivers/install/device-installations-and-system-restarts" target="_blank">this article</a> to check whether your drivers need to be rebooted.</p>

	<li><strong>When no sufficient disk has been installed on the device</strong>:</li>
	<p>When a chosen version requires more disks than the disks that have been installed on the device, a notification will pop up. To fix this problem, do any of the following:
	<ul>
	<li>Select another version.</li>
	<li>Click <strong>{{"Load Drivers"##ActiveBackup-Business##agent_pc_recovery##*agent_pc_recovery*##btn_load_driver}}</strong> in the hardware driver list to load required hardware drivers.</li>

	<ul><li>Select another version.</li>
	<li>Change the installed hard disks.</li></ul>
	</p>
	</ul>	
	<div class="section">
<h4>Note:</h4>
	<ul>
		<li>The capacity of each installed hard disk on the device has to be more than or equal to the corresponding backup disk in the selected version. Even when the total capacity of all installed hard disk is more than or equal to the total capacity of the selected version, the capacity of individual hard disk still needs to be more or equal.</li>
	</ul>
</div>
<li><strong>Check and confirm the summary to start the recovery process</strong>:
<p>Please note that recovery is an irreversible action. Once started, it is not allowed to be stopped and rolled back to where it was before the recovery. Cancellation during the process may prevent the device from booting successfully.<br/>
<img src="../image/summary.png" alt="" /></p>
</li>
<ul>
	<li><strong>When internet disconnected during the recovery</strong>:
	</li>
	<p>Synology Active Backup for Business Recovery Wizard will continuously try to reconnect to the server and resume the recovery when the internet disconnected during the process.

</ol>
<h4>To retrieve "recovery.log" and send it to Synology Technical Support when the recovery fails:</h4>
<p>When a entire device or volume-level recovery fails, you can retrieve the "recovery.log" file and send it to Synology Technical Support for further assistance. Please note that "recovery.log" is only retrievable on Recovery Wizard before you restart or shut down your device.</p> 
<p>To retrieve the "recovery.log" file, please follow the steps below:</p>
<ul>
	<li>For Windows:
		<ol>
			<li>Insert a USB drive to your device which you wish to restore. You can use the same USB drive where the recovery media is stored.</li>
			<li>Click <img class="inline" src="../image/context menu.PNG" width="19" height="19" alt="" /> at the upper-right corner of the wizard to open the context menu.</li>
			<li>Click <strong>Command-line interface</strong> to launch command-line interface.</li>
			<li>Enter the below command to launch Notepad:
			<p><samp>notepad</samp></p>
			</li>
			<li>Choose Open in the notepad, and check the drive letter of the inserted USB drive. For example, if the drive letter of the inserted USB drive is “S”, please enter the commands below to copy the log and command folder to the USB:
			<p><samp>copy X:\ActiveBackup\recovery.log S:</samp></p>
			<p><samp>xcopy /E /I X:\ActiveBackup\resource\command S:</samp></p>
			A message confirming the file copy will appear after you enter this command.
			</li>
			<li>Go to the USB drive where you copied the log file, and send the file named "recovery.log" and command folder to Synology Technical Support for further troubleshooting.</li>
		</ol>
	</li>
	<li>For Linux:
		<ol>
			<li>Insert a USB drive to your device which you wish to restore. You can use the same USB drive where the recovery media is stored.</li>
			<li>Launch Linux recovery wizard command-line interface.</li>
			<li>Enter the command below to check the location of the inserted USB drive.
			<p><samp>fdisk -l</samp></p>
			</li>
			<li>Mount the USB drive. For example, if the location of the inserted USB drive is "/dev/sdb1", please enter the command below to mount the USB drive.
			<p><samp>mount /dev/sdb1</samp></p>
			</li>
			<li>Mount any folder of the USB drive. Here, we take "/mnt" for example. Please enter the command below to mount the folder.
			<p><samp>mount /dev/sdb1 /mnt</samp></p>
			</li>
			<li>Enter the commands below to copy the log and the command folder to the USB drive.
			<p><samp>cp /opt/Synology/ActiveBackupRecovery/recovery.log /mnt/</samp></p>
			<p><samp>cp -r /opt/Synology/ActiveBackupRecovery/resource/command /mnt/</samp></p>
			</li>
			<li>Enter the command below to unmount the USB drive.
			<p><samp>umount /mnt</samp></p>
