Online archiving

We have a Merlin account, and we want to archive all of our locally produced content — from web and print, photos and articles. When we launched in Blox more than a year ago, TN set up an XML export of our web articles. We went live with TCMS two months ago and that is tied to Merlin and gives us articles and photos from print only. But we reversed the workflow and publish to the web from Blox and syndicate it to TCMS for print. I remember hitting a bit of a wall when we asked for photo archiving from Blox, and we did the article export to get something going. Curious how other papers archive online content, especially if you are only on Blox.
