The Windows hibernation feature creates a hidden system file, Hiberfil.sys and uses this file to store information that is needed for hybrid sleep. Disabling hibernation reduces the size of an instant clone's or a View Composer linked clone's virtual disk.
When you make hibernation unavailable, hybrid sleep does not work. Users can lose data if a power loss occurs.
