I’m currently updating our various S3 related Howto topics so that they reflect the latest changes in Discourse and S3. I’ll notify you when that’s done.

Essentially you need to either use two different buckets or a prefix for the backup bucket. For example, the following combinations will work:

1. Different buckets
  - `s3_upload_bucket`: `my-upload-bucket`
  - `s3_backup_bucket`: `my-backup-bucket`

2. Different prefixes
  - `s3_upload_bucket`: `my-bucket/uploads`
  - `s3_backup_bucket`: `my-bucket/backups`

3. Prefix for backups
  - `s3_upload_bucket`: `my-bucket`
  - `s3_backup_bucket`: `my-bucket/backups`
