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

[Ethan Hu]

Hi fellow university computing group execs,

I am one of 2 VPs of Tech at the Computer Science Undergraduate Association
at UC Berkeley, the oldest CS group on campus, a social club that has waxed
and waned since the '70s.

I would like to form an arrangement in which several groups incrementally
back up home directories to each other via an agreed-upon system. Could I
ask about how much space user homedirs currently take up and what
filesystem you use, in addition to your thoughts about this plan?

In the interest of preserving precious alumni data, it is important to
follow all aspects of 3-2-1 backups. Offsite needs to be done properly!
CSUA currently lives in a strange niche: the University took away free Box
subscriptions years ago, and on the other hand, paying for it ourselves is
not worth it, given the amount of user data (2TB in homedirs, 9TB total) we
currently have (as opposed to our OCF brethren, which *does* use a paid
backup provider) and our budget.

I am aware that many execs' terms will end soon, but I am fine with
planning being done ASAP, and implementation of this plan should begin with
new execs coming in immediately with the fall semester (or quarter).

Above all, I hope to deepen connections between computing groups. I am
looking forward to how this goes in the next few months.

Best Regards,
Ethan Hu
