Cache is required for speed - tools can be very slow without it.
Backup/archive are for recovery purposes - if you lose access to
a separate /var partition you might need the files in those 
directories to regain access to it.
Similarly if you have your root filesystem on lvm2, you really
ought to place a copy of the metadata backups for the volume
group holding your root filesystem in /boot.
This doesn't happen automatically yet, but I expect it'll get
added after the first disaster report that could have been averted
with this...

You can specify the file locations in lvm.conf (or by patching
at compile time of course).
