An administrator is performing an upgrade on an ESXi host. Which step can be used to back up the host before the upgrade is performed?
A. Using the vSphere Client connected to vCenter, right-click the host and choose Host Backup.
B. Log into a vMA appliance and run vicfg-cfgbackup to save the ESXi host configuration.
C. Using the vSphere Client connected directly to the host, right-click the host and choose Host Backup.
D. Use PowerCLI to run the host-backup cmdlet to save the ESXi host configuration.
Correct Answer: B
Explanation/Reference:
"So let’s say you reinstall ESXi and that really takes a few minutes. However there might be things you do to customize your hosts like licensing info, multipaths, local users, switchs etc etc. I think you get the idea. Soon you will realize that its really stuff like this what ends up consuming your time. So what you do? In comes vMA. You can use vMA to backup your host configuration to a file and use that file to restore the changes you made to the host. This will save you plenty of time. Follow these simple steps."
vicfg-cfgbackup -s -server IPaddrOfHost /location/BackupFileName (This command will prompt you for a username and pwd as the vMA appliance doesn’t have this. Note the -s stands for save).
You can then FTP or SCP into the vMA appliance and grab this configuration file and store it in a safe/accessible location. Notice I said “accessible” because its important for you to have backups, but these backups are not of any value if you can’t get to them when you need ’em.
