      Article summary

      Atempo Miria provides high performance data protection and migration of large on-prem data to a variety of targets, including 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.

      1. Sign in to the Backblaze web console.
      2. In the user menu in the upper-right corner of the page, select My Settings.
      3. Under Enabled Products, select the checkbox to enable B2 Cloud Storage.
      4. Review the Terms and Conditions, and click OK to accept them. 

      Create a Bucket

      1. Sign in to the Backblaze web console.
      2. In the left navigation menu under B2 Cloud Storage, click Buckets.
      3. Click Create a Bucket.
      4. 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.
      5. Select a privacy setting: Private or Public.
        Note
        You can change a bucket's privacy settings at any time.
        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. If this is your first time creating a public bucket, complete the following tasks to ensure that you have the correct permissions to create a public 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.
      6. If applicable, enable a Backblaze B2 server-side encryption key.
      7. Enable Object Lock to restrict a file from being modified or deleted for a specified period of time.
      8. Click Create a Bucket, and copy the value that is in the Endpoint field; you may need this value later.
      9. Click Lifecycle Settings to control how long to keep the files in your new bucket.

      Create an Application Key

      1. Sign in to the Backblaze web console.
      2. In the left navigation menu under B2 Cloud Storage, click Application Keys.
      3. 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.
      4. Select All or a specific bucket in the Allow Access to Bucket(s) dropdown menu.
      5. Optionally, select your access type (Read and Write, Read Only, or Write Only).
      6. 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).
      7. 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.
      8. 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).
      9. Click Create New Key, and note the resulting keyID and applicationKey values.
      Note
      When you create a new app key, the response contains the actual key string, for example N2Zug0evLcHDlh_L0Z0AJhiGGdY. You can always find the keyID on this page, but for security, the applicationKey appears only once. Make sure you copy and securely save this value elsewhere.

      Configure a Storage Manager

      1. Sign in to Miria.
      2. Select Infrastructure from the Configuration menu.
      3. Click Object storage & application from the right menu.
      4. Click New Storage Manager from the upper-left corner of the screen.
      5. In the Storage manager type menu under Object Storage, select S3 Protocol and click Next.
      6. In the Storage manager name field, enter Backblaze B2.
      7. In the Default network address field, enter the S3 Endpoint URL that you copied earlier followed by :s (for example, s3.us-west-002.backblazeb2.com:s). Leave all other settings as their default values.
        The :s tells Miria to use an https connection.
      8. Click Create.

      Create a Storage Management Container

      1. Click Go Back, and click + (plus) to create a storage management container.
      2. In the Storage container name field, enter your bucket name followed by _smc (for example, miria2024ol_smc).
      3. In the Threads field, enter a value between 10 and 20 depending on your upload bandwidth. For the purposes of this guide, the value 20 was tested.
      4. Enable AVAILABLE AS SOURCE.
      5. Under Manage bucket versioning, enter your Backblaze B2environment variables.
        1. Enter your application keyID in the Access Key ID field.
        2. Enter your application applicationKey in the Secret Access Key field.
        3. Enter your bucket name using only lowercase letters.
        4. Select Manage bucket versioning.
        5. Enable RETENTION MODE, and select Enable compliance mode.

      The following example shows a successfully created storage manager.
