是否可以通过控制台仅备份数据库？

./launcher enter app
discourse backup

在尝试包含上传文件时失败：

...
取消暂停 sidekiq...
完成备份...
创建归档：mysite-2020-02-24-183504-v20200203061927.tar.gz
确保归档尚未存在...
创建空归档...
归档数据转储...
归档上传文件...
异常：lib/discourse.rb:57:in `exec'：归档上传文件失败。
tar: /var/www/discourse/public/backups/default/mysite-2020-02-24-183504-v20200203061927.tar：仅写入 2048 字节，应为 10240 字节

不太确定……@gerhard 或 @vinothkannans 有什么想法吗？

是的，您可以使用以下命令从 Rails 控制台仅备份数据库。

./launcher enter app
rails c
> BackupRestore::Backuper.new(Discourse.system_user.id, with_uploads: false)

嗯，这没有生成备份文件。不过手动备份按预期工作。

有什么日志需要检查吗？

命令输出：

啊，我忘了在末尾添加 .run。它应该是 BackupRestore::Backuper.new(Discourse.system_user.id, with_uploads: false).run。

我对这个主题产生了兴趣，并阅读了大量相关帖子。我的结论是，为了避免出现错误，直接从控制台恢复备份甚至是安全的。那么，通常如何正确操作呢？
