I need to make a copy of my system so I can mess with it and come back in time, if I need. I am not happy with backup options I found, and I am not sure GParted copy is reliable - besides, I need to boot in an USB stick otherwise it does nothing.
DD seems to do the job right. But here is the mystery: I have my experimental Debian in a 32GB partition, so I created a 32GB (exactly) in an external disk using the same ext4 specs. But the attempt of copy results in an error - no espace enough. So I increased the size in 4GB, than DD copied without any errors, but the partition have now 4GB unused space. And most important, how I will copy the partition back if it is bigger than original? Any copy need a bit more space? How much? Is there a way of make a compressed clone?
Also, I don't know if this is the better tool or the better way of doing this, a good tutorial will be nice!
