WikiTeam[1] has released an update of the chronological archive of all
Wikimedia Commons files, up to 2013. Now at ~34 TB total.

I wrote to – I think – all the mirrors in the world, but apparently
nobody is interested in such a mass of media apart from the Internet
Archive (and the mirrorservice.org which took Kiwix).
The solution is simple: take a small bite and preserve a copy yourself.
One slice only takes one click, from your browser to your torrent
client, and typically 20-40 GB on your disk (biggest slice 1400 GB,
smallest 216 MB).
