S3 Browser is a freeware Windows Client for S3-compatible cloud services such as Backblaze B2 Cloud Storage.
Enable Backblaze B2
Before you begin: You must have a Backblaze B2 Cloud Storage account. You can sign up here. If you already have a Backblaze account and the left navigation menu contains a B2 Cloud Storage section, your account is already enabled for Backblaze B2.
- Sign in to your Backblaze account.
- In the left navigation menu under Account, click My Settings.
- Under Enabled Products, select the checkbox to enable B2 Cloud Storage.
- Review the Terms and Conditions, and click OK to accept them.
Create a Bucket
You can use an existing bucket, or you can create a new one. You will need the value from the Endpoint field for the S3 Browser configuration.
- Sign in to your Backblaze account.
- In the left navigation menu under B2 Cloud Storage, click Buckets.
- Click Create a Bucket.
- Enter a name for your bucket.
Bucket names must be at least six characters and globally unique. A message is displayed if your bucket name is already in use. - Select a privacy setting: Private or Public.
Files that are in a private bucket require authentication to perform an action, for example, downloading. Public buckets do not require authentication so you can easily share files. You can change a bucket's privacy settings at any time. - If applicable, enable a Backblaze B2 server-side encryption key.
- If applicable, enable Object Lock to restrict a file from being modified or deleted for a specified period of time.
- Click Create a Bucket, and copy the value that is in the Endpoint field; you may need this value for other processes.
- Click Lifecycle Settings to control how long to keep the files in your new bucket.
Create an Application Key
If you use a bucket-restricted app key, select Allow List All Bucket Names to allow the List All Bucket Names permission to work successfully with the S3-Compatible API. If you do not select this option when you create your app key, you must create a new app key and enable the required permission.
Application keys control access to your Backblaze B2 Cloud Storage account and the buckets that are contained in your account.
- Sign in to your Backblaze account.
- In the left navigation menu under Account, click Application Keys.
- Click Add a New Application Key, and enter an app key name.
You cannot search an app key by this name; therefore, app key names are not required to be globally unique. - In the Allow Access to Bucket(s) dropdown menu, select All or a specific bucket.
- Select your access type (for example, Read and Write).
- Select the optional Allow List All Bucket Names checkbox (required for the Backblaze B2 S3-compatible API List Buckets operation).
- Click Create New Key, and note the resulting keyID and applicationKey values.
