Regarding yesterday's BD security release, I noticed that @jenlampton posted on FB about having a spreadsheet ready, and then later about letting the update madness begin :)
That made me wonder, how do people have Backdrop setup? I thought it might be nice to explain our setups for the benefit of others, and to maybe learn different/better ways of doing things...
I'll start: I have a VPS server on which I've installed Ubuntu, Apache, mySQL, phpMyAdmin, etc. Backdrop is installed in the public root directory, and I use multisites for the 5 or 6 BD sites I run. I don't do the whole development/testing/production thing (never really saw a need, especially since I build mainly small sites for small organisations), so I update everything live. I have nightly backups of both the server (through my VPS host) and websites files and databases (custom bash scripts I've written).
So for me, updating Backdrop is simply a matter of unzipping the new version, copying over the new /core directory, running `drush cc all` (on all sites automatically via a Drush script) and then cleaning up the zip file.
I'd love to hear what others do, if there's things I can do better/more easily/securely, and am happy to share more info about my setup if anyone's interested.
