I used the software to mirror a site the other day and 
later noticed that some files were missing or, rather had 
zero file sizes. I guess they had timed out(?) A couple of 
days later I noticed this and ran an update without 
checking whether the original site was live. But it was 
not. When I came to look at the downloaded files I noticed 
that all files had been purged. Is there any way of 
recovering the original files that were downloaded in the 
first run?
