You're really only left with one option for restoring from tarball, aside from going into rescue mode. First, put the tarball on some sort of removable media (likely an external USB hard drive, given the size). Second, do a fresh install on the system in question. Mount the external media with the tarball. Extract the usual configuration directories (/etc/, /usr/local/, /opt, /var/lib) and /home, after installing the software required.

Hypothetically, you could uncompress the tarball somewhere else and do a straight dd or block level copy, but I have my doubts that would work unless you manipulated the boot loader after, to agree with the uncompressed kernel and content. I agree with ahyes, the bigger picture is coming up with a better backup method. You can backup with tar, but using tar to backup is really more of a supplemental solution to configurations, databases, home directories - not binaries. You're best bet, if using tar to backup everything important, is to create a kickstart image. That way, if you need to restore, you simply run the kickstart and extract your tar.

GIT-TAR-TREE(1) 						    Git Manual							   GIT-TAR-TREE(1)

NAME
git-tar-tree - Create a tar archive of the files in the named tree object SYNOPSIS
git tar-tree [--remote=<repo>] <tree-ish> [ <base> ] DESCRIPTION
THIS COMMAND IS DEPRECATED. Use git archive with --format=tar option instead (and move the <base> argument to --prefix=base/). Creates a tar archive containing the tree structure for the named tree. When <base> is specified it is added as a leading path to the files in the generated tar archive. git tar-tree behaves differently when given a tree ID versus when given a commit ID or tag ID. In the first case the current time is used as modification time of each file in the archive. In the latter case the commit time as recorded in the referenced commit object is used instead. Additionally the commit ID is stored in a global extended pax header. It can be extracted using git get-tar-commit-id. OPTIONS
<tree-ish> The tree or commit to produce tar archive for. If it is the object name of a commit object. <base> Leading path to the files in the resulting tar archive. --remote=<repo> Instead of making a tar archive from local repository, retrieve a tar archive from a remote repository. CONFIGURATION
tar.umask This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write bit. The special value "user" indicates that the archiving user's umask will be used instead. See umask(2) for details. EXAMPLES
git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -) Create a tar archive that contains the contents of the latest commit on the current branch, and extracts it in /var/tmp/junk directory. git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz Create a tarball for v1.4.0 release. git tar-tree v1.4.0^{tree} git-1.4.0 | gzip >git-1.4.0.tar.gz Create a tarball for v1.4.0 release, but without a global extended pax header. git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar Get a tarball v1.4.0 from example.com. git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar Put everything in the current head's Documentation/ directory into git-1.4.0-docs.tar, with the prefix git-docs/.
