 **Possible Values:** [`False`]/`True`  
-Download files for only newly added links when running the `./archive` command.

+Download files for only newly added links when running the `./archive` command.  
+
+By default, ArchiveBox will go through all links in the index and download any missing files on every run, set this to `True` to only archive the most recently added batch of links without attempting to also update older archived links.
+
+*Note: Regardless of how this is set, ArchiveBox will never re-download sites that have already succeeded previously. When this is `False` it only attempts to fix previous pages have missing archives, it does not re-archive pages that have already been archived. Set it to `True` only if you wish to skip repairing missing older archives on every run.*
