If you start from the top, the engine will be, by 
default, authorized to crawl everywhere on this 
website. Use strict filters (-* and then +..), such as:

-* +www.[sourceweb].com/whateveryouwant/* +*.png 
+*.gif +*.jpg +*.css +*.js +*.pdf +*.doc

Then you may want to use --update (for.. updating) 
which may be bette in this case. Ah, depth=2 may NOT 
be sifficient, also (3 may be better if you have N+1 
links?)

Warning: The cache is absolutely necessary for 
updates, don't use the --cache=0 option
