Acronis Cyber Backup (Advanced) for Virtual Host is designed and optimized specially for agentless backup of virtual machines: these editions allow you to perform backups of virtual machines without the need to install an agent on each guest system - agents only need to be installed on hosts.
The table below shows the main differences between agentless backup and using Agent for Windows/Agent for Linux to back up a virtual machine.

Agent-based and agentless backup may have different speed depending on many factors such as workload complexity and priority, server capacity and utilization, local area network (LAN) and WAN bandwidth, and more. Since no two environments are the same, it is recommended to test which type of backup works best for your infrastructure and better suits your needs.
