Sign Up to BackBlaze B2 Cloud Storage

The Managed Backup service allows using BackBlaze B2 Storage accounts. Service providers can attach their B2 accounts to MBS and back up their customers’ data to BackBlaze B2 storage. To start using BackBlaze B2 with the Managed Backup service, you should create a BackBlaze account, sign up for the B2 Storage service, and then connect MBS with your B2 account.

In this article, you will find out:

How to Create BackBlaze Account

To create a BackBlaze Account, proceed as follows:

  1. Go to the BackBlaze website.

  2. Click the "B2 Cloud Storage" button at the top of the screen.

  1. Enter your Email and password and click Sign Up for B2.

  2. On the "Sign In" page that appears, enter your credentials one more time and then click Sign In.

  1. You will be prompted to enter your phone number to verify your account. Just click the "Go to My Settings" button.

  1. Enter your password and phone number, and request the code.

  2. Enter the code sent to your phone and click Verify.

How to Get the Account ID and Application Key

To get the Account ID and Application Key, proceed as follows:

  1. As soon as you are logged in, go to the Buckets page.

  1. Click the "Show Account ID and Application Key" link.

  1. In the pop-up window, either click Create New Master Application Key to create root-level keys or click Create Application Key to create an application key with limited permissions. Please note that it is recommended to create application keys for backup purposes, as master keys allow unrestricted control over every single operation within your B2 account and are therefore dangerous to distribute among users.

  1. A pop-up window will appear with a set of credentials you have just created. Make sure to write these down somewhere, as they are only shown once. If the keys are lost, a new set of keys will have to be generated.
