Hi Vadim,

In general backing up ESXi host configuration is supported for ESXi hosts running from USB flash drive. The error you get is unique to particular host configuration (for example we've seen such problem when the /bootbank link was referring to /tmp which is non-standard setup) and in order to investigate it we'll need to get an image of your ESXi host flash drive captured with 'dd' utility for example. If this is not possible then capture ESXi system logs from vSphere client (File->Export->System logs) and contact our support team for further assistance.

Thank you.
