Back up utility

Require a backup utility to copy modified files from workstations to network server. Must utilize file size/date for comparison - NOT archive bit. Must do an intelligent backup - ie check if file first exists on server and only copy if it doesn't. Must also track deleted files in order to perform a proper point in time backup/restore. Similar functionality to file "synching" programs available on the net, but with some unique requirements. More specific details available to selected candidates.
