What are you trying to backup? VMs or the host itself? If host, hypervisors are usually meant to be disposable since you can import config from VMFS and VMX. You can backup configuration files within ESXi just to not redo complicated networking config. If you want to backup VMs, use any 3rd party software (yes, there are no built-in backups). If you are running free ESXi, you are pretty much forced to use agent-based backup or use scripts from Github - https://github.com/lamw/ghettoVCB.
