To back up a partition, you can use the parted command to perform the following steps:

sudo parted -l

Select the partition you wish to back up. Pay attention to the name and size of the partition to avoid backing up the wrong one.
Run the following command to back up the selected partition. Replace /dev/sdX with the actual name of the partition you want to back up, and replace backup.img with the location and filename where you want to save the backup:

sudo parted /dev/sdX --align=opt mkpart primary ext4 0% 100%
sudo dd if=/dev/sdX1 of=backup.img bs=4M status=progress

The above command will create a new partition identical to the original partition and copy its content to the backup.img file.

Please note that backing up a partition may take some time, depending on the size of the partition and the computer’s performance.
