Getting Heroku logs for past few weeks

I'm trying to get the production logs for the past few weeks off of heroku but when I do heroku logs, it just returns a few lines showing the production log for today.

Any way to get heroku logs for the past few weeks?

Thanks.

• Heroku only provides you with access to the last 100 lines.

  tfe : Yep, there is no way around this. Better logging solutions is one thing the company is working on for the near future, however.
