It would be great to have built-in support for Backblaze B2 storage (compatible with S3). Below is the simple suggested patch that enables B2 storage files simply using “b2” as a region specifier. Patch to amazon-s3-api.php, line 127: switch ( $region ) { case ‘b2’: return ‘s3.us-west-000.backblazeb2.com’; break;
Please add an Amazon S3 “Browse” or lookup button to avoid garbage in garbage out.
