RE: The fsf
My notes from the previous Unix admin told me to do that because, there was a previous tar done before that. I did not include it in the post.
The first tar in the script was
tar cvf /dev/rmt/0n /restore /etc/passwd /etc/shadow /etc/group /export/home/oracle >> /data/unix_backup.log
He told me it's because he wanted the password file and oracle profile backed up at the beginning of the tape for disaster recovery purposes.

why did you do that? You might try it again without that command.

TM(4) Kernel Interfaces Manual TM(4)
NAME
tm - TM-11/TU-10 magtape interface
DESCRIPTION
The files mt0, ..., mt7 refer to the DEC TU10/TM11 magtape. When closed it can be rewound or not, see below. If it was open for writing,
two end-of-files are written. If the tape is not to be rewound it is positioned with the head between the two tapemarks.
If the 0200 bit is on in the minor device number the tape is not rewound when closed.
A standard tape consists of a series of 512 byte records terminated by an end-of-file. To the extent possible, the system makes it possi-
ble, if inefficient, to treat the tape like any other file. Seeks have their usual meaning and it is possible to read or write a byte at a
time. Writing in very small units is inadvisable, however, because it tends to create monstrous record gaps.
The mt files discussed above are useful when it is desired to access the tape in a way compatible with ordinary files. When foreign tapes
are to be dealt with, and especially when long records are to be read or written, the `raw' interface is appropriate. The associated files
are named rmt0, ..., rmt7. Each read or write call reads or writes the next record on the tape. In the write case the record has the same
length as the buffer given. During a read, the record size is passed back as the number of bytes read, provided it is no greater than the
buffer size; if the record is long, an error is indicated. In raw tape I/O, the buffer must begin on a word boundary and the count must be
even. Seeks are ignored. A zero byte count is returned when a tape mark is read, but another read will fetch the first record of the new
tape file.
FILES
/dev/mt?, /dev/rmt?
SEE ALSO
tp(1)
BUGS
If any non-data error is encountered, it refuses to do anything more until closed. In raw I/O, there should be a way to perform forward
and backward record and file spacing and to write an EOF mark.
