I would think the amount it would help would depend highly on the nature of your day-to-day file changes. Block de-duplication would add over file de-duplication if you have a lot of (large) files that change incrementally, such as logs. It would be interesting to hear back from users of ZFS about their own anecdotal experiences. ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ BackupPC-users mailing list [email protected] List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
