* Grants enough privileges to the configured user so that it can run mysqldump. * Adds a nixos test. * Use systemd timers instead of a cronjob (by @fadenb). * Creates a new user for backups by default, instead of using mysql user. * Ensures that backup user has write permissions on backup location. * Write backup to a temporary file before renaming so that a failed backup won't overwrite the previous backup, and so that the backup location will never contain a partial backup. Breaking changes: * Renamed period to calendar to reflect the change in how to configure the backup time. * A failed backup will no longer result in cron sending an e-mail -- users' monitoring systems must be updated. Resolves #24728
