Yesterday I set up offsite backups on s3, and it took me a while to figure out where to fill in my s3 credentials.
The place to set this is in
admin/site_settings/category/files which I guess I would have known if I were already set up to use S3 to host uploaded files. Because I don’t, I was lost. To help someone like me in the future, I guess the helper text should actually read something like this:
Upload backups to S3 when complete. Make sure you have filled in your s3 credentials in the Files settings.
