When dumping to a file it should not take this long. But in this case it might be that dump is waiting for restore, since the space in a pipe is not infinite. Also, when dumping mounted partitions you should use the -L flag with dump. But in a case like this there is little reason to mount the old partitions. If the failing disk was giving trouble, you might find errors in /var/log/messages.
