wget files by modification date

Question

Is there a way for wget to only fetch FTP files that have been modified after a certain date (when fetching recursively)?

The application here is that I need to sync with several servers nightly, but I only need the data going forward from a couple days ago. The --mirror flag would suffice except that syncing the rest of the data (even just once) would take forever.

Answer 1

wget can mirror once and then after this only get later items with the --timestamp flag. I'd suggest reading the info page for it, which has a good explanation, and checking if this gives you the behaviour you are looking for.
