Audience question about backup strategy. Answer: two layers. (1) Litestream continuously replicates every change (once per second) to Cloudflare R2, giving an essentially live copy and point-in-time recovery within the last 48 hours — also used to replicate production/staging into the dev environment with one command. (2) A cron-scheduled daily script runs SQLite's built-in `sqlite3 backup` command and uploads the resulting backup-format file to S3/R2 as a separate full dump.
