To fix this, deploy the ESX agent on the ESX server whose virtual machines you want to back up and recover
Acronis Backup & Recovery 10 Management Server provides an easy way to deploy Agent for ESX/ESXi to every VMware ESX or ESXi server whose virtual machines you want to back up
As a workaround, install Acronis Agent for Linux in the Linux virtual machine
The user under which you are trying to log in does not have Administrator rights
Click Configure -> ESX Hosts -> Add
Delete two registry keys to fix the issue
Click Configure -> ESX Hosts
The typical reason for a VM to be missing in the backup or replication wizard (unavailable for selection) is that this VM was created by Acronis vmProtect and is in fact a replica VM. It is not possible to back up replica VMs by default, however this may be possible after additional adjustments
This has been fixed
Fixed in Acronis Backup 11.5 (Acronis Backup & Recovery 11.5). As a workaround, revoke the license key and install the Acronis Agent in the guest OS
This has been fixed in Acronis Backup & Recovery 11
Install Agent for Windows inside the virtual machines
After an update to Acronis Cyber Protect 15 Update 3 (Build 28035 or 28122) a Virtual Host license does not allow backup of both host and virtual machines.
If the license is assigned to the host, backup of virtual machines fails and VM details show "No license". If the license is assigned to VM(s), backup of host fails.
Protection plan creation may fail with an error similar to:
The protection plan cannot be used or updated for ‘<hostname>’ because the device does not have a license.
You have a virtual host with VMs, and licenses for Virtual Host workload (such license can be used to back up 1 Hypervisor Host Server and up to an unlimited number of virtual machines that are residing on the Hypervisor Host Server).
When you check the details of host and VMs with applied plans, license assignment is correct.
However, if you look under Settings -> License usage, one or more of Virtual Host licenses are assigned to VMs without Agent, or the licenses are shown as "not assigned".
- You are using Hyper-V or ESXi clusters with Virtual Appliance, and licenses for Virtual Host workload (any edition),
It is not possible to assign licenses to all nodes of the cluster: when assigning the license to the host, the virtual machine loses the license and backup fails due to lack of license. If the license is assigned to a virtual machine instead, the host loses the license and cannot run backups.
