See options of package `epstopdf' or section "1.5 Configuration".
I prefer "update, prepend".

Currently there is only option "update". The pdf file isn't overwritten,
if it's newer than the eps file. Or with option "append", it searches
for PDF files first (and doesn't trigger the conversion if the PDF
file exists.)
