Not knowing your architecture I can't commen ton the perofmance issues but
the cause may be something else.

I an no Fastback expert but it is my understanding that CDP should not be
used on constantly open files like Exchange, otherwise the snapshot
activity would be never ending. The snapshots should be setup on some
period. In that way Exchange can flush its logs to disk before a "snapshot"
of the CHANGED blocks can occur.

This is also why you don't want to use CDP on system drives.
