This program is designed to be used in conjunction with a version of win32tar
that I found that DOES work with tape drives on windows NT.  However the
executable only could be found and no mention of who did the port.

The drawbacks of win32tar is that it only lets you read/write one saveset on
a tape.  It does however write a filemark after each saveset.  To get around
this problem I designed lktapeutils.

First you must erase a tape or it must be new to use with tar.  You can erase
it in ntbackup or use the lktapeutils -h command.

Then you write a saveset on the tape using tar
ie. tar -cf\\.\tape0 -Vsaveset_1 -vvvv

now if you wanted to read the saveset you would issue the command
tar -tf\\.\tape0 -vvvv

or alternative use the lktapeutils -l command which will list all tar
savesets on the tape.  Now to write another saveset on the tape you use
the lktapeutils -s 1 command to space over the first saveset then you
again issue the command: tar -cf\\.\tape0 -Vsaveset2 -vvvv which will 
save everything in the current directory.  Now there are two savesets on
the tape but even if you issue the tar -tf\\.\tape0 command twice in 
a row it will only list the first saveset and same goes for restoring it.

To get around this you would issue the command lktapeutils -s 1 and it
would position the tape at the beginning of the second saveset and now you
can list it or restore it.  Alternative you can use the command lktapeutils -l
to list all saveset on the tape.  For a complete list of lktapeutils commands
issue lktapeutils -h, for a complete list of tar commands issue tar +help.
