On the other hand Time Machine does take advantage of a kernel based mechanism that watches file activity and does its best to take advantage of that information to avoid scanning the filesystem when it does a backup. That's the context of the message thread that I pointed to (again, for completeness) http://lists.freebsd.org/pipermail/freebsd-hackers/2008-June/024730.html The thread seemed relevant given the context of backup systems that watch filesystem io. g. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
