I want to turn my entire SSD into a full-blown back-up in a fashion that allows me to explore it in the future, without insane hardware.
Preferably something managable, like a single ISO file. For which I've found this command:
dd if=/dev/sda of=/media/blabla/backup.iso
But I'm afraid if I do it, and I clear my SSD afterwards, I might lose all the data.
Can someone here confirm that after performing command above, I will (if command completes successfully) receive that iso file, that with specific user-level program I will be able to access all the information that original SSD had?
