A local system has asked me how to duplicate their install tapes for the NCR Tower. They are conserned that they have to rely on one set of tapes if their system ever fails. Does anyone know how this can be done? Any help would be appreciated. ----------------------------------------------------------------------- Saul A.

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
