How to Backup and Restore VMware ESXI Host Configuration

How to Backup and Restore VMware ESXI Host Configuration

Having healthy ESXi hosts is a key to success when running virtual machines. That’s why it is better to back up ESXi configuration. Thus, if something goes wrong with an ESXi host, its configuration can be restored in a few minutes without spending a lot of time to configure an ESXi server from scratch.

The backup procedure is:
1. Connect to ESXi host via SSH.
2. Run the command below:
vim-cmd hostsvc/firmware/sync_config
This command is to make sure that all the changes of configuration would be saved to the target file.
3. Run the command below:
vim-cmd hostsvc/firmware/backup_config
You need to be aware that the "*" is the IP or FQDN of the host so you should manually replace it.
4. Open a web browser and copy and paste the link into it. Type Enter.
The backup file would be downloaded then. It could be found in the folder Download whose name contains "configBundle" and host FQDN. That's the way to export ESXi configuration.

The restore procedure is:
2. Run the command below:
vim-cmd hostsvc/maintenance_mode_enter
This command is to put the ESXi host into maintenance mode
3. Copy the backup file to ESXi host
4. Run the command below:
You should replace "/backup_location" with the actual directory.

Thank You very Much
It was a Great Video with Full Detail of Restoring ESXI

[goyopinto]

Excellent and amazing video !!you are and excellent teacher

[playalisticpaul]

Thanks for your video.

My initial problem is that i disabled module vmw_ahci and now i am not able to enable it back via cli. After a reboot it is always reverted to disabled state. Already tried every tutorial available, but no luck. I can see that it is disabled in the esx.conf.

What i want to do now is to follow your tutorial but then change the parameter in the esx.conf and tar everything back, encrypt the tar and restore that modified backup.

What is the crypto-util command to re-encrypt the tar?

[testettttestttess]

[ciroiriarte]
