Preserving Ownership w/tar

I'm trying to make a backup of a directory tree on Solaris 8. I'm doing this with my own ID, not root. The problem I am running into is when I extract the archive, all files are owned by me and the group is my default group. The man page lists this as the default behavior when executed by a non-root user.

Are there any options that I can use to override this behavior (to create the files with their original owners and groups)? If not, are there any other tools available with Solaris that would allow me to accomplish this?

NAME
groups - Displays your group membership SYNOPSIS
groups [user] DESCRIPTION
The groups command writes to standard output the groups to which you or the specified user belong. The Tru64 UNIX operating system allows a user to belong to many different groups at the same time. Your primary group is specified in the /etc/passwd file. Once you are logged in, you can change your active group with the newgrp shell command (see sh). When you create a file, its group ID is that of your active group. Other groups that you belong to are specified in the /etc/group file. If you belong to more than one group, you can access files belonging to any of those groups without changing your primary group ID. These are called your concurrent groups. NOTES
The /etc/passwd and /etc/group files must be on the same node. EXAMPLES
To determine your group membership, enter: groups The groups to which you belong will be displayed. For example: devel prod FILES
Contains group information. Contains user information. SEE ALSO
Commands: csh(1), ksh(1), sh(1) Functions: initgroups(3), setgroups(2) groups(1)
