I just came across this article today, tried it out, and works superbly.
It explains how to set up an AppleScript to find all of your completed tasks up to 1 month back and creates a report-like note in Evernote. This is the first time I've used ran the AppleScript utility, and the article explains how if you're a first timer too. I had to do a search on how to view the scripts folder in your hidden Library folder.
I've just incorporated this into my monthly workflow:
- run script to generate report of last month's completed tasks
- in OF, move old data into archive
- & sync to reduce the database size

The only thing I wish the script could do is probably include any notes and attachments that belong to a task and display the date/time the tasks were marked completed. That would go a long way into keeping an easy to read archive of my tasks and its associated notes.
