ESXi host configuration recovery can be used to quickly recover the ESXi server

This article applies to:

  • Acronis vmProtect 7
  • Acronis vmProtect 8
  • Acronis Backup for VMware 9 (Acronis vmProtect 9)


Acronis Bare Metal Recovery (BMR) of the ESXi host allows you to restore ESXi server binaries and patches, ESXi configuration, and missing VMs (VMs present in backups, but missing on the datastores; VMs should be backed up separately) after the ESXi server is recovered and started.

(!) Bare Metal Recovery supports only VMware ESXi version 4.1 or later.

(!) ESX is not supported for Bare Metal Recovery.


ESXi host configuration backup:

  1. To create an ESXi host configuration backup task, go to Actions -> ESXi Configuration Backup;
  2. Select the ESXi host configuration that you want to back up by selecting the ESXi host from the list of ESXi hosts/vCenters;
  3. After selecting the ESXi host, enter access credentials in the popup that appears. 
  4. (!) ESXi host configuration backup is performed via SSH, so SSH access will be forcibly enabled for the ESXi host to back up;
  5. Select the location for storing ESXi configuration backup and specify the archive name;
  6. In the When to Backup step set a schedule for the backup task:
  7. In the How to backup step specify the retention rules and other options:
  8. To complete the task creation, specify the task name. Default name is “Backup of ESXi configuration [date/time]”.

ESXi host configuration restore:

(!) ESXi Host Restore wizard is only available from Acronis Bootable Media interface. See Acronis vmProtect: Acronis Bootable Media.

  1. Boot the host from Acronis Bootable Media and select ESXi Host Restore:

  2. Select the Archive and the Recovery Point that will be restored:
  3. Select the locations that will be used to recover VM backups and provide credentials for each location. These locations will be used to restore virtual machines after ESXi host is recovered.
  4. The Configure Local Datastores step shows the detected disks, their size and datastores already present on them (if any). Select the Use for new datastores check box to use the HDD for a new datastore creation.

    If the datastore on disks matches with the datastore in the original configuration (stored inside the ESXi configuration backup), its name appears in green. If the datastore is detected but does not match the original configuration, its name appears in yellow. If the detected datastore is going to be cleaned up for a new datastore creation, its name appears in red.

  5. In the Configure Virtual Network step, the software scans for NICs and automatically matches them to vSwitches present in the saved ESXi configuration. Check the result of an automatic mapping and modify it, if needed. (Keep in mind that mapping in original and restore systems may be different). In order to change the automatic mapping, you can do the following:
    1. Click on the particular network adapter (e.g eth0).
    2. Navigate to the virtual switch section.
    3. Choose the proper vSwitch from the list of available virtual switches.
  6. Click OK to start the recovery.
