Do I need a swap partition to use hibernation?

Sun Apr 19 13:08:10 UTC 2020

That idea for using that area with dual purposes, dates back to the time when disk space was a scarce commodity

The hibernation data is generally stored in the swap partition.

Like any other partition, except it is of type "Linux Swap"  and you use
mkswap to create the "file system".  You won't need 30 GB.  8GB *should* be
enough, depending on how much you use the swap under normal use.  If you
regularly dip well into swap space under "normal" usage, you should make the
swap partition larger.
