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. 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 the Backblaze web console.
- In the user menu in the upper-right corner of the page, select 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 the Backblaze web console.
- 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.
- 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 later.
- Click Lifecycle Settings to control how long to keep the files in your new bucket.
1. Verify your email address.
2. Have a payment history on file, or use the credit card form to pay a small fee that is credited to your account balance.
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.
- Sign in to the Backblaze web console.
- In the left navigation menu under B2 Cloud Storage, click Application Keys.
- Click Add a New Application Key, and enter an app key name. Please note: You cannot search an app key by this name; therefore, app key names are not required to be globally unique. Key names are limited to 100 characters and can contain letters, numbers, and "-", but not I18N characters, such as é, à, and ü.
- Select All or a specific bucket in the Allow Access to Bucket(s) dropdown menu.
- Optionally, select your access type (Read and Write, Read Only, or Write Only).
- Optionally, select the Allow List All Bucket Names checkbox (required for the B2 Native API b2_list_buckets and the S3-Compatible API S3 List Buckets operations).
- Optionally, enter a file name prefix to restrict application key access only to files with that prefix. Depending on what you selected in step #4, this limits application key access to files with the specified prefix for all buckets or just the selected bucket.
- Optionally, enter a positive integer to limit the time, in seconds, before the application key expires. The value must be less than 1000 days (in seconds).
- Click Create New Key, and note the resulting keyID and applicationKey values.
