## 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 the image. The duration of the video depends on your needs and the video will be played at 3x speed. You will receive a preview of the video along with a notification email. Please note that Synology VMM 2.3 or above must be installed before you can enable this feature. The cluster of Synology VMM and backup destination should be on the same volume to perform backup verification. For further information on how to create a backup task with the live video verification, please refer to here.

#### Note:

- To perform backup verification, your Synology NAS needs to be connected to the Internet to activate h.264 video codec if codec has never been activated on your Synology NAS before.
