    Article Summary

    You can use Commvault to back up your files to Backblaze B2 Cloud Storage. This article shows you how to set up Backblaze B2 as a Commvault cloud storage target.

    If you use the latest version of CommCell, you must use the Commvault web interface to set up Backblaze B2. For CommCell versions prior to Version 11 (service pack 17), you must configure Backblaze B2 as a library using the Commvault console. In either case, you must have your Backblaze B2 application key and bucket ready to set up the connection.

    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.

    1. Sign in to your Backblaze account.
    2. In the left navigation menu under Account, click 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 your Backblaze account.
    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.
      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.
    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 for other processes.
    9. Click Lifecycle Settings to control how long to keep the files in your new bucket.
    Note
    Copy the S3 endpoint that is displayed for use in another step.

    Create an Application Key

    Application keys control access to your Backblaze B2 Cloud Storage account and the buckets that are contained in your account.

    1. Sign in to your Backblaze account.
    2. In the left navigation menu under Account, click Application Keys.
    3. 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.
    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.
