• When performing virtual machine backups, users can select Backup Verification to implement scheduled trial runs of the restoration, which will be performed in Virtual Machine Manager. The entire process will be recorded as a video for reference, so that users can confirm that the backup is able to be successfully restored. The duration of the video can be specified, which will begin recording once Virtual Machine Manager starts running the backup image. • In Advanced settings, users can set up the script and other information for individual virtual machines. • Select one or multiple virtual machines for which you want to specify the script or credential settings. • Click Script to browse the script executed in the guest OS and specify the script processing mode. • Successful script execution required to continue: The virtual machine backup process will stop if the script fails to be executed. • Ignore script execution failure and continue VM backup: The virtual machine backup process will continue even if the script fails to be executed. • In VMware vSphere: Click Set credentials to specify the username and password for virtual machines. • In Microsoft Hyper-V: Click VM Information to configure the credentials, operating system, and IP address for the virtual machine. Notes: • Active Backup for Business 2.2.0 and above versions support the concurrent backup of up to 50 personal computers, physical servers, and virtual machines. The actual number varies by RAM capacity: • Less than 8 GB: 10 • Between 8 GB and 32 GB: 30 • More than 32 GB: 50 • Application-aware backup uses Microsoft Volume Shadow Copy Service (VSS) or VMware Tools to make sure that the backed up data of Linux and Windows virtual machines is consistent. For VMware, make sure that you have the latest version of VMware Tools. For Hyper-V, your virtual machine must support VSS and it must be enabled on the target device. • Setting up the script and enabling the virtual machine script execution requires the credentials of your virtual machine. An error message will be displayed if the credentials are missing. • Synology Virtual Machine Manager must be installed to enable Backup Verification. • For VMware vSphere: • VMware Tools must be installed to execute a pre-post script. • If you are using a free version of an ESXi hypervisor, CBT must be manually enabled. Refer to this article for more information on how to manually enable CBT. • Data transfer compression cannot be enabled on vSphere 5.1 and below. Backup Configuration 10
