That is a lot  of work whereas the trend is to have  less and less peered
lists. Disk  space is only  expensive on old  machines, and then  only if
management  refuses to  buy secondhand  disks of  the same  technology. I
bought  a secondhand  3380-AE4  + a  suitable  disk controller  (3880-3),
guaranteed by IBM to  be in good state, and the total  cost was some $12k
for 5G of disk space + string head logic + controller (that is, if I want
to expand I can add up to 3 units  at a lower cost). This is not a museum
case but something about  5-6 years old. If there is  no space to archive
the list on  one of the peers,  it is perhaps not necessary  to keep that
peer.  That is,  nowadays the  main reason  for having  peers is  that it
provides several access points for the archives.
