The fsck for none of these filesystems will be able to deal with
a filesystem that big. Unless, of course, you have a few weeks
to wait for fsck to complete.

Backup and restore are similar problems. When part of the filesystem
is lost, you don't want to have to wait for a full restore.

Sounds simple? Well, the hard part is figuring out exactly which
part of the filesystem you need to restore...

I don't see ZFS, ext4 or XFS addressing these issues.

IMHO chunkfs could provide a much more promising approach.
