Conventional backups can be faster that that! I have not used netbackup but you should be able to configure netbackup to run several backup streams in parallel. You may have to point netbackup to subdirs instead of the file system root. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
