GNU Tar for NT w/APSI tape extentions
(see "NTRMT" below for rmt server)

NTTAR
=====

This is a port of the GNU-tar 1.11.8 for Windows-NT
using the WIN32 tape API. Only nessesary modules are
included in this package. It is based on the structure
of the port of tar 1.10 with ASPI-support of
"chris@alderan.sdata.de". I made a little change in tar.c
to prevent removing the "/" of the entered pathname.

The modules are tested with a HP-SureStore Tape 5000
and Windows-NT 4.0.

The devicename of the tape is builded by default with "0"
--> "\\.\tape0". Other names can be reached through an
environment variable named TAPEID. e.g. TAPEID=1
makes "\\.\tape1".


Enter tar --help to get full syntax-description
of the tar-command.

The filename "/dev/ct" specifies the cartridge-tape
and "/dev/nrct" specifies the no-rewind-cartridge-tape
(no rewind on close).

tar -c c:/some/dir              - creates the tar-file "tar.out"
tar -cf archive.tar c:/some/dir - creates the tar-file "archive.tar"
tar -cf /dev/ct c:/some/dir     - creates a tar-file on tape
                                  and rewinds the tape on close.
tar -cf /dev/nrct c:/some/dir   - creates a tar-file on the tape
                                  and does *not* rewind the tape on close

To append one tar-file to the end of another
just use the "/dev/nrct" device.
E.g:  1) tar -cf /dev/nrct c:/some/dir
      2) tar -cf /dev/ct d:/some/other/dir

Multi volume archives are supported by the tape-functions().
So, you may backup your whole disk in one GO to a multi
volume tape archive. E.g.:  tar -cvMf /dev/ct c:/ d:/ e:/ f:/
writes your c:, d:, e: and f: - drive to the tape archive.

You might have noticed the use of "/" instead of "\"
to separate dirnames in a pathname. So, don't use the
backslash in pathnames, use the normal slash.

If you have any suggestions or errors please feel free to send me an
e-mail.

history:
6/2/97 - Added support of -b parameter to define blocksize
         So the default blocksize is 20 * 512 and not 512 bytes

NTRMT
=====

I added an NT service which responds to UNIX tcp rexec "rmt"
commands.  This allows you to run dumps from your unix (& linux)
boxes to your NT tape drives.

I also added an "unix like" mt command - some of just can live
without "mt rew" and "mt rewoffl"...

The rmt server can run as a console application but is intended to run
as a service (rmt -d). 

To install it as a service move the rmt.exe to the place you intended
it to stay (c:/winnt/system32 is a fine place) and then run "rmt -i"
to install and start it.  You can uninstall it later with "rmt -u".

The rmt service will show up in the "Services" control panel and will
respond to start & stop requests.

You should be able to remake from the sources using Visual C 4.2 with
"nmake -f rmt.mak".  (gnu make will work also).
