In worst... in ultra-worst abysmal inexpected exceptional
and unbelievable narrow cases, when you don't have or can't
access a backup (which you should have even when using ZFS),
and you _need_ to do some forensic analysis on disks, ZFS
seems to be a worse solution than UFS. On ZFS, you never
can predict where the data will go. Add several disks to
the problem, a combination of striping and mirroring
mechanisms, and you will see that things start to become
complicated.

I do _not_ want to try to claim a "ZFS inferiority due to
missing backups", but there may be occassions where (except
performance), low-level file system aspects of UFS might be
superior to using ZFS.
