Clonezilla
Clonezilla
Clonezilla is a set of utilities that we can use to create, restore, and deploy images.
We can use Clonezilla in two ways: the Live Clonezilla distribution and the command-line tool. The process of creating and restoring the image is the same for both approaches. Therefore, we’ll go with the former.
Our Linux system is installed on the /dev/sda disk — specifically, on the /dev/sda1 partition. Our data partition is /dev/sda2, and that’s where we’ll write the image of /dev/sda1.

Backup to a Disk Image
how to create an image to an external drive
Using the Gnome Disks Utility
-
1. Run the Gnome Disks utility from the Ubuntu programs menu - WRITE DISKS
- Select the external drive or disk, and then choose “Create Disk image…”.
- Create a file name for the image, choose the folder to store the image, and then press the “Start Creating…” button to begin the process.
- Wait for the process to finish. It could take a couple of hours to finish.
Using the Terminal
To backup to a compressed image using a terminal, simply run the following command:
sudo sh -c "dd if=/dev/sda status=progress | xz -c > /media/cupc/image.img.xz"
Replace /media/cupc/image.img.xz
with the location where you wish to store your disk image.
It may take a couple of hours to complete.

if=/dev/sda
Is cloning the entire disk and of=/dev/sdd1
Is writing to a partition. Which doesn't make much sense.
You may want to clone the entire disk onto another disk
dd if=/dev/sda conv=sync,noerror status=progress bs=64k of=/dev/sdd
Or yet clone to a compressed image
dd if=/dev/sda | gzip > /sda.img.gz
And restore like so
gzip -d /sda.img.gz | dd of=/dev/sda
to create the image. There where four partitions in my sda

* Microsoft reserved

KB5028166 is slowing down PCs, games
Beyond the enterprise world, gamers have also been hit by Windows 10’s July 2023 update. Several users reported their games and apps becoming laggy after the update.
“The latest update has slowed my PC to a crawl, with Chrome and other apps taking minutes to open. Webpages are often delayed or display a ‘page not responding’ message,” a user reported.
Users report that their games and apps have become noticeably laggy since the KB5028166 installation. Even popular games, such as Cyberpunk, that previously ran smoothly are now fraught with annoying loading pauses and disappearing icons, which negatively affects the gaming experience.
The update has generally slowed down systems, leading to a surge in user frustration. Users face performance issues even after attempts to restore speed by clearing caches, running system scans, and rebooting their devices.
