That's How It Happened

I've accidentally deleted almost a year's worth of pictures hosted on my server, in an ill-timed hosting overhaul. I have managed to manually rescue this week's posts, but I fear for the previous 12 months. Anyone have any bright ideas for recovering things that aren't backed up elsewhere? Google cache and archive.org have already proved useless. If I can't think of an automated solution, it will be a long haul, trawling through various discarded hard drives, inboxes and ancient servers looking for the snaps individually.
