[committee] Berkeley CSUA 3-2-1 Backups Proposal (please forward to other groups)

[Ethan Hu]

Hi Gary,

Thanks for reaching out! Yesterday, the three clubs currently planning (no
one's in the US besides CSUA) formed a discord, which you should join!

Here's a doc for planning:

The latency from anywhere on Earth should be low enough for backups, and
when restoring, any speed is better than not having an offsite copy!

Best Regards,
Ethan Hu
