So isn't this a good reason to use the dump/restore utilities to begin 
with?  They allow a full level 0 dump and up to 9 different incremental 
levels with the added benefit of higher incremental levels including all 
changes since the last full level 0 backup, right?  So no matter how 
many incremetals written, a full restore will only require the lastest 
full level 0 backup and the highest incremental backup created since then!
