为什么每日备份的大小会减少？

Yes totally, the site setting you are thinking of is include thumbnails in backups which is default off.

Every setting you have described already exists… browse through your site settings.

You people do know it’s a nightmare at times guessing what you call different stuff (even though settings searching is quite good actually)? :slight_smile:

What I was thinking of was automatic resizing of ANY image (recognized) to lower quality jpg (or whatever internal site choice).

Files/“png to jpg quality” might do that but is obscure. Png only? Way past my bedtime so I’m probably just thick tonight.

And while I’m at it, is there any guide like “top 100 settings you might want to change after setting up your first site - and why”?

Top 10? :smiley:

大家好，
我注意到本月我的备份大小大幅减少，而据我所知，我们这边并没有任何显著的变化。我想确认一下，这是否属于预期情况，还是我需要对某些问题感到担忧？@sam，你是否了解任何可能导致此变化的调整？以下是显示我们观察到约减少三分之一的截图：

谢谢！

你使用的是哪个版本？上传文件是存储在 S3 还是本地？

我猜是清理任务删除了大量上传文件。建议你提取 2019-07-03 和 2019-07-06 的文件并生成差异对比。是否有不该缺失的文件缺失了？

感谢您回复我，抱歉未包含版本号等明显细节。我们目前使用的是 v2.3.1 +12（稳定版频道，我想）。2019-07-03 到 2019-07-06 这段时间很可能正好涵盖了我们进行更新并修改部分备份逻辑的时期。上传文件是本地存储的（正如您所见，我们的论坛非常小）。

查看备份内部内容是个很棒的主意。以下是文件大小差异所在：

因此，是整个 optimized 目录消失了。我推测这是为了节省备份空间而有意为之，特别是在发现 这个提交 之后。所以一切看起来都没问题。谢谢。:slight_smile:
