Usually the way such as on Windows is to use hibernate but Linux has issues here
such as kernel modules and initrd and enabling secure boot has disabled
hibernate on Debian for a number of years now when it was supposed to be for a
short while. I'm not sure about the situation on OpenBSDs hibernate. There are
also firmware attacks to consider too.
