---------------------------------------------

Hi Markus. Based upon the assumption that you add the new 'db.preserve.backup' property to nutch.default and set to true by default then yeah I'm a +1. This is a nice patch and saves some annoying manual work.

> The webgraph's outlinkDB is the single source for all scoring jobs and GB's that eventually come out. In case of disaster, that didn't happen yet, it should be able to preserve back up just like other DB's. This means users with an existing outlinkdb must move it from a crawl/webgraphdb/outlinks/ to crawl/webgraphdb/outlinks/current/.
