## Backup Verification

To ensure the backup reliability, Synology Active Backup for Business integrates with Synology Virtual Machine Manager to verify the backups. Synology Virtual Machine Manager (VMM) will shoot a video when importing the backup image and running up the image. The duration of the video is decided by the user and the video will be played at 3x speed. Users will receive a preview of the video along with the notification email. Please note that Synology VMM 2.3 or above must be installed before you enable this feature, and the cluster of Synology VMM and the backup destination should be on the same volume to perform the backup verification. For further information on how to create a backup task with the live video verification, please refer to here.
