Installed on the droplet at /usr/local/bin/wizwar-backup.sh, cron 07:17 UTC daily: mirrors /var/lib/wizwar to spaces:kestrel-wizwar-backups/ wizwar/current and keeps 90 days of dated snapshots. Ledgers are append-only, so no service stop is needed. The script no-ops with a log line until Spaces credentials land in /root/.config/rclone/ rclone.conf.
