Hi Guys,
When uploading a backup to discourse through the console, it creates lots of 404 errors.
In the end my backup got uploaded. Just wondering why i get so many 404 (around 3000 thousands)
When you upload a backup, it’s cut into little chunks which are uploaded one by one. For each chunks, the browser asks the server if it already has it. The 404 is the server telling the browser that it hasn’t received the chunk yet. This allow for backup uploads to be resumable
