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. -- gentoo-user@lists.gentoo.org mailing list
