IMO the best argument for not using a system utility if there's an equivalent Perl-based solution: portability. File::Copy will work on any system that can run Perl. cp won't work on any platform where the file duplication utility isn't called that.

NAME
invsync - Synchronizes system inventory SYNOPSIS
/usr/bin/invsync DESCRIPTION
The invsync utility creates a Master Synchronization Inventory (MSI) file and a Customized File Inventory (CFI) file. These files can be used to preserve the customized or modified state of your system in the event of a new installation. The MSI file contains a complete list of files installed by the setld utility and the state of those files when they were installed. The CFI file contains the names of those files installed by the setld utility that have been customized or modified since the installation. The files listed in the CFI file are overwritten if you perform a new installation of the operating system. You must have superuser privileges to run the invsync utility. The invsync utility calls the usync utility to create the MSI file. After the MSI file is created, the invsync utility calls the udetect utility to compare the state of the files shown in the MSI file with the current state of the files installed on the system. If a file state differs, an entry is written to the CFI file. Edit the CFI file to remove the entries for files that you do not want to back up. The CFI file and the MSI file are written in the setld inventory file format. For more information, refer to the stl_inv(4) refernce page. RESTRICTIONS
You must have superuser privileges to run the invsync utility. FILES
