In order to duplicate magnetic media on your UNIX system you need:
the source media,
the computer, and
another media large enough to hold data read from the source media.
Destination disks or tapes, must already be formatted and your computer
must be able to read the disks, tapes, or data cartridges.
Because the procedure for duplicating media is identical with disks,
magnetic tapes, and tape cartridges, for simplicity we'll use floppy disks.
There are basically two methods for duplicating the disks:
1. On a system with ONE floppy drive, you must first copy
the source floppy onto the hard disk (perhaps into /usr/tmp)
and then from the hard disk onto the destination floppy using
the cpio utility.
the tar utility.
cpio
SYNTAX
cpio -[io] [pathname]
FUNCTION
cpio copies in and out of file archives.
OPTIONS/FLAGS
-i copy in, extracts from standard input, which is
assumed to be the results of a previous cpio.
-o copy out, reads standard input for filenames and
copies to standard output. It is presumed that
standard output will be redirected to a floppy
or tape.
-d directories are created as needed for output.
-c writes header information in ASCII character
form for portability.
-v Causes a list of filenames to be printed.
For the floppy drive
/dev/rsave1
The command to read the floppy
onto the hard drive would be
cpio -icdv < /dev/rsave1
and the command to copy from the hard
drive to the floppy would be
ls | cpio -ocv > /dev/rsave1
Let us use the cpio command
to copy from the floppy to the
hard disk on your system. So
please type:
cpio -icdv < /dev/rsave1
Now put another floppy of
identical density that has
already been formatted into
the drive.
Let us use the cpio command to
copy from hard disk to the
floppy disk on your system. So
please type:
ls | cpio -ocv > /dev/rsave1
XENTAR
tar
SYNTAX
tar [key] [name ... ]
FUNCTION
tar saves and restores multiple files from an
archive medium, which is typically a storage
device such as a floppy disk, tape, data cartridge,
or a regular file.
OPTIONS
c - creates, a new archive. Writing begins at the
beginning of the archive. The command implies
a rewrite function.
f - causes tar to use the next argument as the name
of the archive, rather than the default archive
specified in /etc/default/tar.
x - the named files are extracted from the archive.
v - verbose, causes tar to display the name of each
file it treats.
b - causes tar to use the next argument as the
blocking factor instead of default. The
default is 1; the maximum is 20.
For the floppy drive /dev/rfd048ds9
For the tape drive /dev/rmt0
The command to write the media onto the hard drive would be:
tar xf /dev/rfd048ds9
tar xf /dev/rmt0
and the command to copy from the hard drive to the media would be:
tar cf /dev/rfd048ds9 .
tar cf /dev/rmt0 .
Let us use the tar command
to copy from your media to the
hard disk on your system. So
please type:
tar xf /dev/rfd048ds9
tar xf /dev/rmt0
Now put another floppy or tape
of identical density that has
already been formatted into the
drive.
Let us use the tar command to
copy from your hard disk to the
media in the drive. Please type:
tar cf /dev/rfd048ds9 .
tar cf /dev/rmt0 .
