Acronis Cyber Backup 12.5, Acronis Cyber Protect 15 and Acronis Cyber Protect Cloud support Kernel-based virtual machines (KVM). Backup of KVMs can be done by installing Agent inside the guest OS of the virtual machine (agentless backup is not available). When an agent is installed in the guest system, the backup and recovery operations are the same as with a physical machine. Backup and recovery of KVM machines can also be done with bootable media.

To protect KVMs with Acronis Cyber Backup 12.5, you need Acronis Cyber Backup Advanced Virtual Host license: with one license you can install an unlimited number of Agents inside virtual machines on a single host.

To protect KVMs with Acronis Cyber Protect 15 in on-premises deployment mode, you need Acronis Cyber Protect - Backup Advanced Virtual Host license or Acronis Cyber Protect Advanced Virtual Host license (or Universal License): with one license you can install an unlimited number of Agents inside virtual machines on a single host.

Note that using any other type of license besides Virtual Host will require an Advanced edition. Example: backup agent running inside Windows Server KVM VM will require Acronis Cyber Protect Advanced Server license. In this scenario, one license per VM is required.

To protect KVMs with Acronis Cyber Protect Cloud or Acronis Cyber Protect 15 in cloud deployment mode, you need quota for Virtual Machine(s).

The following KVM management tools have been tested by Acronis for Acronis Cyber Backup 12.5 and Acronis Cyber Protect compatibility:

• Proxmox 
• oVirt
• QEMU

If you are using a different KVM management tool that is not on the list above it does not mean that it is not supported. The detection of KVM hypervisor by the backup agent installed inside VM is done by checking signatures of virtual hardware. These checks are independent of the type of KVM management tools used so the above list is intended to be used only as a quick reference (it will be expanded in future).
