调研方向

从 apps/backup/lib/Service/ExternalFolderService.php 的第 385、452 和 543 行附近开始，沿着 apps/backup/lib/Service/UploadService.php 中的上传路径以及 apps/backup/lib/Cron/Manage.php 中的 cron 条目进行追踪。将此流程与 FileEventsListener.php 第 107、209 和 357 行的 files_versions listener 进行比较，然后重现 SFTP 上传失败，并验证 restore point 是否能够在不出现报告中的 NoUserException 的情况下完成上传。

由索引模型根据 Issue 内容生成。
