vultr doesn't let you shut down a server while it's creating a snapshot. however, it *did* let me run "shutdown now", which shuts down the server, and *then* start creating the snapshot.
i hope my snapshot doesn't get corrupted or anything... it takes quite a while to create one, and i really don't know how long it's going to take. i've been leaving the console window open waiting for it to be ready, but there's no progress bar or anything.
honestly, i'm pretty scared right now.
the good news is that even if i've somehow completely destroyed the server and it'll never work again, i have a 4-hour old backup i can restore from. i'd lose four hours of mastodon data which the other instances believe i have, which might make federating behave a little weird.
