Is it possible to use the Archive::Tar module with relative path names, so that I can archive all files of the /home/domain1/public_html directory, and extract the archive file on another server: /home/domain2/public_html?

There are a number of commercial options available for this, I also found this article that may be of use to you.

This is very acheivable of you are intending to backup the tar file to another server on your network.

Yes, Archive::Tar does relative pathames. Here's a little command line script (call it at.pl) to demonstrate:
#!/usr/bin/perl
use Archive::Tar;
die "Usage: at.pl <dir> [<dir>...]\n" unless @ARGV;
my $tar = Archive::Tar->new;
for my $dir (@ARGV) {
$dir =~ s'/+$'';
$tar->add_files(glob "$dir/*");
}
$tar->write('files.tar');

Start it from the root of the directory you want to save, e.g.:
$ cd /home/domain1
$ at.pl public_html

For full details, take a look at perldoc Archive::Tar. If you're using this for anything but a small number of files, you should probably use the os tar cmd instead. Also, this script is very basic - it doesn't do much error checking, and doesn't handle nested directories correctly.
