Andrew has a point. dd is not a good choice. FS don't like it if some parts of
them are in a different state than others.
Also, with dd, everytime you restore, you also restore fragmentation - oh and
a bigger partition? Can be tricky.
There is nothing wrong with tar. In fact tar is great for this job. dd not.
