ext4 will probably cope with that. XFS definitely has very high
limits though I admit I don't know what they are.
XFS is also a few exobytes.
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.
