New server setup, best practice?

Wed Aug 10 19:10:53 UTC 2016

Again, depends so much on the specific circumstance… I just set up a $5/month VPS with it, with 15GB total space, storing only the past couple of days’ worth of e-mail for a handful of users.

I’ve also set up systems for thousands of users, with a terabyte of SSD storage for “local, recent” stuff plus mbox-purge processes exporting stuff to a couple of dozen terabytes of local HDD storage and monthly processes moving stuff elsewhere using NFS and/or rsync.

I’d rather mount NFS than SMB for performance/permissions reasons.
