FreeBSD's softupdates should make filesystem state always consistent, metadatawise. Or so I think I remember, its been a while. That might aleviate some of the problems noted on the dump page I referenced. > On the other hand I've certainly routinely seen cases of people using dd > (rsync, cpio, tar etc) and coming to grief at restore time.

I use rdiff-backup for my backups but then again I have low requirements wrt. consistency outside file-level. I have considered LVM snapshots since I use LVM already but havent bothered so far.
