As long as i have read in the lists it is not possible to run RRDTool over NFS.
As a workaround you can use Apaches "rewrite engine" module. So you store all
rrds on your collecting 3 servers, setup apache on each of them and melt the
whole stuff together via your Webserver and rewrite engine. Have a look at the
apache documentation for additional information. A quick hint is on the end of
this mail.

If you plan to back things up, try to use mirroring. At least, i know mirroring
is NO backup. Additionaly new Sun Solaris comes out with a brand new feature to
take 'snapshots' like you may know it from NetAppFiler.
