Government Backup
The US Government has an awful lot of data, and it's in a lot of places. In 2016, elections were held that indicated deep sea changes in goals and ideals (although previous transitions have always contained such changes). Inspired by this, a number of groups and efforts have risen up to ensure backups of all government data possible are made off-site.
This page contains overviews of the effort by all the teams.
