It seems to me this is only true if you're talking strictly about full backups. Any kind of incremental or differential backup is likely to do a significant amount of reading in order to determine what files need to be sent, unless it's storing data about each backup locally. rsync, for example, needs to read from both filesystems to build up its file list. -- David Brodbeck System Administrator, Linguistics University of Washington -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
