However, backup/restore are so much faster than doing a tar/untar. If I do a backup of my FS, wipe the disk, will the 'restore' cause the same (ineffecient) directory layout to appear on disk? I wouldn't think so since the directory layout is controlled by the kernel, but I do know that dump/restore are much lower-layer tools than tar, so they may possibly have layout information embedded in them. Is my assumption correct? Nate To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
