Thanks, Michal. I haven't actually read the rsync manpage to this detail, but I do use rsync for backups this way, but a bit differently - yet more understandable without referring to manpages... ;) the procedure is something like this: cd /backups rm -rf tmp/ cp -al $yesterday tmp/ rsync -r --delete -t ... /filesystem tmp mv tmp $today That is, link the previous backup to temp (which takes no space except directories), rsync current files to there (rsync will break links for changed files), and rename temp to $today. /mjt - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
