Is there any way to STD in Debian?

[YOYO]

Hello everyone,
Recently, I need to cut off power supply with all my running tasks saved.
But it seems that the hibernate mode provided in Debian only allows me to 
Suspend to Ram(STR, or S3 mode in ACPI).
Is there any way to Suspend to Disk (STD, or S4 Mode in ACPI) in Debian?
Thank you for your replies in advance.


Best Regards,
Richard

Do you have a swap partition? It has to be sufficient in size and is
necessary for Hibernation to work.
You need to edit "/etc/initramfs-tools/conf.d/resume" file to provide an
UUID of a swap partition, or a path,
in case of LVM, to a swap partition and run:
# update-initramfs -u

    Example for traditional disk partitioning scheme:
$ cat /etc/fstab | grep -iE "swap"
UUID=e990fa6d-3f82-4d65-b6a1-542e240718fc     none    swap sw      0       0

$ cat /etc/initramfs-tools/conf.d/resume
RESUME=UUID=e990fa6d-3f82-4d65-b6a1-542e240718fc

    Example for LVM partitioning scheme:
$ cat /etc/fstab | grep -iE "swap"
/dev/vg0-nvme/lv1-swap  none    swap    sw      0       0

$ cat /etc/initramfs-tools/conf.d/resume
RESUME=/dev/vg0-nvme/lv1-swap

While that is the easiest way by far, I was recently told that the
"resume-from" kernel option can enable hibernation to a non-swap area. I
think. I have not done this. Look in the archive for a thread this month
(9/2024) entitled "hibernate area".

But yes, I use hibernation every night.
