The backup process does not support restoring to later builds. This requirement can be overridden by using the –f

option.

3. Start the vSphere CLI on a host other than the host you want to restore and log in.

4. Run the vicfg-cfgbackup command with the –l flag to load and restore the backup file to the host.

vicfg-cfgbackup --server <ESXi-host-IP> -- portnumber <port_number> --

protocol <protocol_type>-- username <username> --password <password> -l

<backup_filename>

The -portnumber and -protocol options are optional. If you exclude them, the defaults are port 443 and protocol

HTTPS.

NOTE: If you do not specify a password in the command line, you are prompted for one when the command

executes. For example:

vicfgcfgbackup --server 172.17.13.211 --username root –l backupdate.dat

After a successful restore, the system reboots using the new configuration. For complete instructions on backup

and restore commands, see the

VMware ESXi Embedded and vCenter Server Setup Guide

at vmware.com/support/

pubs.

Image Recovery

The procedure described in this section restores your system to a bootable state, but does not restore the per-system

licensing activation information. If you have a valid support subscription, Dell Support can help you with the re-imaging

process and with any licensing issues. To contact Dell Support, see "Contacting Dell".

If you require a new license from Dell Support, but need to have the system up and running as soon as possible, you may

use the one-time 60-day trial of all enterprise-level features including HA, DRS, and vCenter Server. It is recommended

to request the new license as soon as possible following an image recovery to ensure you have your new license before

the 60-day trial period expires. This process takes less than 60 days.

Image Recovery For ESXi Embedded Edition

Image recovery reinstalls or recovers the ESXi embedded image. To perform image recovery for flash-based systems:

1. Download the Dell customized ESXi ISO image from support.dell.com .

2. Burn the ISO image to an optical media.

3. Turn on the system and press <F11> (one-time boot menu) during the POST.

The system displays Entering Boot Menu… in the upper right corner of the screen. Continue with the POST

process. After the initial boot is complete, a text menu of all bootable storage devices is displayed.

4. Select the optical drive where your installer media is located. For internal optical drives, select the device and

press <Enter>.

The recovery environment starts.

5. Follow the on-screen instructions to complete the recovery process.

NOTE: If you see a fatal error, double check that no other USB-based storage devices are connected to the system.

The system reboots and launches ESXi. If this does not happen, reassign the order of your boot devices placing the

internal storage highest in the boot order list. For more information, see the manual that shipped with your system.

6. Set the correct licensing mode.

7. After reimaging, reconfigure ESXi and import any virtual machines you would like to run on this system.
