Compression will reduce the storage requirements for non-duplicate data. As an example, I have a system that I rsync the web application data from a whole bunch of servers (zones) to. There's a fair amount of duplication in the application files (java, tomcat, apache, and the like) so dedup is a big win. On the other hand, there's essentially no duplication whatsoever in the log files, which are pretty big, but compress really well. So having both enabled works really well. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
