我正在尝试通过 定期备份 ( OnCalendar=daily) 到我的保管箱rclone。由于它在笔记本电脑上运行，因此我使用Persistent=true.如果我唤醒笔记本电脑，网络需要几秒钟的时间才能恢复。因此，预计唤醒后的第一次尝试会失败。但是，我不明白为什么我会得到Start request repeated too quickly error.

根据配置，在触发故障之前，12 小时内最多应进行 5 次尝试。我的推理有什么问题吗？
编辑：版本是systemd 252（252.1）
直接运行服务可以按预期工作。
systemctl Reset-failed --user rclone-copy-dropbox.service
systemctl start --user rclone-copy-dropbox.service

答案1
为什么不让该服务仅在网络启动并联机后运行？
After=network-online.target
Wants=network-online.target
然后在笔记本电脑唤醒并且网络连接起来后，服务就会运行。
