Create tarball
The Unix tar command creates an archive of files and directories while preserving directory structure, file permissions and ownership information. This command is ideally suited for creating backups of most types of data. Many open-source and commercial backup applications use the tar command.
The basic syntax of the tar command with some common options for creating a “tarball” and unpacking one, respectively:
tar cvf tarball.tar tar xvf tarball.tar
The example below uses tar to copy directory /usr/openv to /usr/openv2
mkdir /usr/openv2 cd /usr/openv du -sk openv tar cvf /usr/openv2/tarball.tar . cd /usr/openv2 tar xvf tarball.tar rm tarball.tar
*by default tar will not follow links > can force it to w/t parameter
In the following example we create a tarball of all *.conf files found in /etc/directory. This can be useful for making a quick backup of your server’s vital configuration files before messing with them.
tar cvf - `find /etc -name "*.conf" -print` > /var/tmp/etc_conf.tar

I have a PERL script creating a TAR archive via PERL’s Archive::TAR class. I get a listing of the files & directory structure by recursing through the tree & putting all into a list.
Then I use: $TarObject->create_archive
($ArchiveFile, $CompressionLevel, @FilesToTar); where I have used compression levels 2 & 9. These create TARs of about 40+ MB.
When I retrieve the TARs to my workstation I attempt to run them through tar -xzvf and I get:
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
gzip: stdin: invalid compressed data–format violated
tar: Child returned status 1
tar: Error exit delayed from previous errors
I have attempted to use gzip & uncompress as well.
Any ideas?
Thanks

OT, A little further research led me to tweaking my code to set the transfer mode to binary and that was it, I was able to completely untar & gunzip the files after that. You get best answer when I can choose.
Thanks

I got the command prompts from this site and I keep getting the response; nothing to do.
What could be going wrong?
I just installed the OS so I know Flash is not on my computer
