I woud like to bakcup my PC which uses Fedora 36, but by using tools like dd or any other open-source tool available, these only makes a copy or clones the whole disk including the free space (which I do not really need to copy). Because of that I am not able to store the backup on my PC's disk.
I have seen many tutorials where the bakcup goes to an external disk, but since I do not have one, I was wondering if there is a trick ro tool that I am missing for this task.
