This isn’t a problem, just something I just noticed now when I’m playing around with importing stuff from different sources. I did a bar-export of my site 1.5 year ago and the file is still available to download. Nothing wrong with that but the file is 1.5 GB and it seems like a waste of space. I noticed that the markdown export was scheduled to be deleted after 2 days … so 1.5 year seem a bit long. 
Thanks, we’ll get this fixed. I think 2 days was probably too short but definitely shouldn’t stick around for a year.
