For a short period, it did not copy context, but now it can. It will copy directory structures intact and copies links and symlinks as is (by default). tar --xattrs --selinux --one-file-system -cf - /dir | (cd /new/path; tar -xf -) should do the job as root user. You can even add the -S option to handle sparse file efficiently. > I know rsync will resync where it left off if I encounter a problem, > what about dd?
