Configuration Backup and Restore Procedures

It is recommended that you back up your VMware ESXi configuration after you complete the initial setup on a routine

schedule that fits your datacenter environment. Backing up your configuration captures the license code (host serial

number). You need the license code if you use the installer media to restore the ESXi image.

To backup or restore the configuration information, you must use the VMware vSphere CLI. The vSphere CLI is available

in:

• vSphere CLI package—vSphere CLI package can be installed on either Linux or on Microsoft Windows

operating systems.

• vSphere Management Assistant (vMA)—vMA can be deployed on an ESXi host.

Both of these packages are available for download from vmware.com. For information about setting up and running the

vSphere CLI, see the

VMware vSphere Command-Line Interface Installation and Reference Guide

and

VMware ESXi

Embedded and vCenter Server Setup Guide

at vmware.com/support/pubs.

The backup and restore steps given in this section assume that:

• You have already imported the vSphere CLI to a system other than the one you want to backup or restore.

• You have installed the Windows or Linux management Application Programming Interfaces (APIs).

Backing Up The Configuration Of Your ESXi Host

To back up configuration data of a host:

1. Start the vSphere CLI.

2. Run the vicfg-cfgbackup command with the -s flag to save the host configuration to the specified backup filename.

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

protocol <protocol_type> --username root --password root_password [-s

<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 –s

backupdate.dat

NOTE: If your administrative password includes special characters, such as $ or &, you must include a backslash

escape character (\) before each special character.

Restoring The Configuration Of Your ESXi Host

To restore the configuration data of a host:

1. Turn off any virtual machines that are running on the host you want to restore.

2. Optionally, restore the host to the ESXi build number used when the backup file was created.
