I'm executing the command:
wget -b --no-clobber -nc -w 0 -Q 0 -r -E -e robots=off -U mozilla -t 0 --no-dns-cache -4 -R gif,jpeg,tif,jpg,pdf,bmp,png,css,js http://www.mywebsitearchive.com
Problem: If I re-run the command (when necessary if wget abruptly stops) I get duplicates for [some] files, such as example.html and example.1.html. Oddly enough a .2.html .3.html is never created. Any idea how to prevent this?
