The ONEVDC control panel on RealHOST hosting has one very useful functionality that allows you to create an instant snapshot of the server at a specific point in time.
It is convenient to use this opportunity if you need to roll back the server state to the desired time, after a breakdown, unsuccessful setup, or testing.
Configuration should be done in the ONEVDC cloud server control panel https://onevdc.net
