Show us the output of the dump command which didn't work as you 
expected.  Right when it starts it tells you what level of dump it is 
doing and when it thinks the last relevant dump was.  This may not be 
the problem, but it's the best place to start!

Btw, I think your -B 1000000000 is not the best way to go.  Just use -a 
instead.
