We assume you are copying disc-to-disc within the same computer.
Disc mirroring or snapshot solutions are going to be fastest - depends on what type of filesystem this is and whether you have spare discs.
First find out if we can process this filesystem at all and get some stats:
# How big and how many inodes?
df -k /filesystem
# Can we access every inode? Is the number of files similar to "df" ?
find /filesystem -xdev -depth -print | wc -l
Of the unix commands the best combination is "find" piped to "cpio -p". See the "man" pages for both commands. Some versions of "cpio" will not work for large files (check this first on your system).
The copy should not be to a directory under the master. For speed this works best if the copy is on a different filesystem.

I need to copy a directory from a production system to a test system on the same Aix server. However I need to ensure that the soft links are preserved as part of the copy ( therefore I guess the cp command is not the way to go )

VERSION
This man page documents version 1.2 of libtar.
DESCRIPTION
The th_get_*() functions extract individual fields from the current tar header associated with the TAR handle t.
The TH_IS*() macros are used to evaluate what kind of file is pointed to by the current tar header associated with the TAR handle t.
The TH_ISLONGNAME() and TH_ISLONGLINK() macros evaluate whether or not the GNU extensions are used by the current tar header associated
with the TAR handle t. This is only relevant if the TAR_GNU option was used when tar_open() was called.
