Backup to DigitalOcean Spaces fails if uploads and backup are both set to S3

not being able to share buckets

Yeah, that’s just a simple explanation and a recommendation. However, there are multiple configuration options:

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

Multisites always store the backups in <s3_backup_bucket>/backups/<site_name>.
