The Backblaze adapter gives the possibility to use the Flysystem filesystem abstraction library with backblaze. It uses the Backblaze B2 SDK to communicate with the API.


Via Composer

$ composer require mhetreramesh/flysystem-backblaze


use Mhetreramesh\Flysystem\BackblazeAdapter;
use League\Flysystem\Filesystem;
use BackblazeB2\Client;

$client = new Client($accountId, $applicationKey);
$adapter = new BackblazeAdapter($client,$bucketName);

$filesystem = new Filesystem($adapter);

Using ApplicationKey instead of MasterKey

If you specify only the $bucketName when creating the BackblazeAdapter, your application key must be the master key. However, if you specify both bucket name and bucket id, you do not need the master key and can use a single-bucket key. Fetch your bucket id using the b2 command line tool b2 get-bucket <bucketName>

$client = new Client($accountId, $applicationKey);
$adapter = new BackblazeAdapter($client, $bucketName, $bucketId);


Here is the complete guide of all available options.
