from what I can tell, it uses something like rsync under the covers, puts a copy on the central server and on each 'client' machine. There is an optimizer that will sync from the 'closest source', so if you have 3 machines at home and one at the office, if you change or add a file on one machine at home, they will 'share' the file directly with each other and the central server, and the office machine will appear to share the file a bit more slowly. That is only by observation, not from any real vendor information. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
