Thanks for your useful advice, methyl
Btw, when i tar a dummy file(4824483840 bytes) into a blank tape on the solaris server.
What is 9422820 referring to?
Is this 9422820 bytes of the masterfile filled in the tape?

tar
TAR(1) General Commands Manual TAR(1)NAME
tar - tape archiver
SYNOPSIS
tar [ key ] [ name ... ]
DESCRIPTION
Tar saves and restores files on magtape. Its actions are controlled by the key argument. The key is a string of characters containing at
most one function letter and possibly one or more function modifiers. Other arguments to the command are file or directory names specify-
ing which files are to be dumped or restored. In all cases, appearance of a directory name refers to the files and (recursively) subdirec-
tories of that directory.
The function portion of the key is specified by one of the following letters:
r The named files are written on the end of the tape. The c function implies this.
x The named files are extracted from the tape. If the named file matches a directory whose contents had been written onto the tape,
this directory is (recursively) extracted. The owner, modification time, and mode are restored (if possible). If no file argument
is given, the entire content of the tape is extracted. Note that if multiple entries specifying the same file are on the tape, the
last one overwrites all earlier.
t The names of the specified files are listed each time they occur on the tape. If no file argument is given, all of the names on
the tape are listed.
u The named files are added to the tape if either they are not already there or have been modified since last put on the tape.
c Create a new tape; writing begins on the beginning of the tape instead of after the last file. This command implies r.
The following characters may be used in addition to the letter which selects the function desired.
0,...,7 This modifier selects the drive on which the tape is mounted. The default is 1.
v Normally tar does its work silently. The v (verbose) option causes it to type the name of each file it treats preceded by the
function letter. With the t function, v gives more information about the tape entries than just the name.
w causes tar to print the action to be taken followed by file name, then wait for user confirmation. If a word beginning with `y'
is given, the action is performed. Any other input means don't do it.
f causes tar to use the next argument as the name of the archive instead of /dev/mt?. If the name of the file is `-', tar writes
to standard output or reads from standard input, whichever is appropriate. Thus, tar can be used as the head or tail of a filter
chain Tar can also be used to move hierarchies with the command
cd fromdir; tar cf - . | (cd todir; tar xf -)
b causes tar to use the next argument as the blocking factor for tape records. The default is 1, the maximum is 20. This option
should only be used with raw magnetic tape archives (See f above). The block size is determined automatically when reading tapes
(key letters `x' and `t').
l tells tar to complain if it cannot resolve all of the links to the files dumped. If this is not specified, no error messages are
printed.
m tells tar to not restore the modification times. The mod time will be the time of extraction.
FILES
/dev/mt?
/tmp/tar*
DIAGNOSTICS
Complaints about bad key characters and tape read/write errors.
Complaints if enough memory is not available to hold the link tables.
BUGS
There is no way to ask for the n-th occurrence of a file.
Tape errors are handled ungracefully.
The u option can be slow.
The b option should not be used with archives that are going to be updated. The current magtape driver cannot backspace raw magtape. If
the archive is on a disk file the b option should not be used at all, as updating an archive stored in this manner can destroy it.
The current limit on file name length is 100 characters.
