Bob,

ADM, with an underlying ZFS filesystem, will provide a great archiving 
solution
when fully implemented.  It allows for file replication, migration from 
disk to
tape/optical/more disk, copies any number you may want, and allows for 
policy management
of the archives.  It's underlying media management is provided by
MMS (http://www.opensolaris.org/os/project/mms/).   We follow the standards
are are open sourced.
