[Dirvish] Full backup every time

Looking at the log:
>> Number of files: 155036
>> Number of files transferred: 942
Out of 155 thousand files, only 942 were transferred. That seems pretty 
good.

>> Total bytes received: 8768410
Less than 9 meg were transferred.

>> total size is 60891647542  speedup is 6440.01
A speedup of 6 thousand times is pretty good.

Go to the vault directory and do a:
du -csh *

I believe that will show the good news.
