One (1) quota for virtual machines is used when protecting a virtual machine agent-less (using Acronis Agent for Hyper-V or Acronis Agent for VMware, installed on the host).

One (1) quota for virtual machines is used when protecting a virtual machine with an agent installed within its operating system.

Two quotas will be used if one VM is protected both agentless and agent-based. We recommend choosing one option for each VM: either install Acronis Agent inside or use agentless backup.
