1日に複数回のバックアップは可能か、サーバーダウン時の安全性は?

I understand, I think it’s a little safe to only have one backup per day, if the community is very busy there is a risk of losing data since the closest backup could take 24 hours… Returning to the subject, can you tell me if adding an S3 bucket the Backup files go directly to S3 or are they also saved on the machine where the speech is hosted?
