Then use dd(1) and the no rewind tape nodes. The tapes contain a sequence of files, some are cpio archives and others filesystem images or bootable kernels. Just dd the files from tape to disk, remove and 0-length files you get (this happens sometimes) and then write them back to the second tape. With two tape drives, just dd from one to the other until there are no more files on the first. -- -Mike Wescott mike.wescott@ncrcae.Columbia.NCR.COM
