Thanks for your reply, Blake
So what's your advise, as you say the incremental repair has some flaws, should 
i use it mixed with full repair or just run full repair only ?

In practice pre-4.0 incremental repair has some flaws that can bring deleted 
data back to life in some cases, which this would address. 


You should also evaluate whether pre-4.0 incremental repair is saving you time. 
The same flaws can cause *a lot* of over streaming, which may negate the 
benefit of repairing only the unrepaired data.

So you means i am misleading by this statements. The full repair only needed 
when node failure + replacement, or adding a datacenter. right?

Where are you seeing this? If your incremental repairs work properly, full 
repair is only needed in certain situations, like after node failure + 
replacement, or adding a datacenter.
