Connecting Backblaze B2

This guide walks you through connecting a Backblaze B2 storage destination to Pluton.

Prerequisites​

Before connecting B2, you need:

  1. A Backblaze account - Sign up here
  2. An Application Key with access to your buckets

Getting Your B2 Credentials​

Step 1: Create Application Keys​

  1. Log into your Backblaze account
  2. Go to App Keys in the left sidebar
  3. Click Add a New Application Key
  4. Configure your key:
    • Name: Choose a descriptive name (e.g., "Pluton Backups")
    • Access: Select appropriate permissions (typically "Read and Write")
    • Bucket: Choose "Allow access to all buckets" or select specific bucket
  5. Click Create New Key
  6. Important: Copy both the keyID and applicationKey immediately - the applicationKey is shown only once

Step 2: Note Your Bucket Name​

You'll need an existing bucket name or create one:

  1. Go to Buckets section
  2. Note the bucket name you want to use
  3. Or click Create a Bucket to make a new one

Connecting to Pluton​

Step 1: Add Storage​

  1. In Pluton, navigate to Storages
  2. Click Add Storage button
  3. Select Backblaze B2 from provider list

Step 2: Configure Connection​

Fill in the required fields:

  • Storage Name: A friendly name (e.g., "B2 Production Backups")
  • Account ID: Paste the keyID from your Application Key
  • Application Key: Paste the applicationKey you saved
  • Bucket Name: Enter your B2 bucket name

Step 3: Advanced Options (Optional)​

Additional settings available:

  • Hard Delete: Enable to permanently delete files instead of hiding them (use with caution)
  • Endpoint: Leave blank for standard Backblaze endpoints
  • Download URL: Optional Cloudflare CDN URL for faster downloads with free egress

Step 4: Test and Save​

  1. Click Test Connection to verify credentials
  2. If successful, click Save
  3. Your B2 storage is now ready for backup plans

Common Issues​

Authentication Failure: Verify you're using the Application Key ID (not your master Account ID) and that the key has appropriate permissions.

Bucket Not Found: Ensure the bucket name exactly matches (case-sensitive) and your Application Key has access to it.

Region Issues: Backblaze automatically handles regions - no manual configuration needed.

Best Practices​

  • Use Application Keys with minimum required permissions
  • Enable lifecycle rules in B2 to manage old backup versions
  • Consider using Backblaze's free Cloudflare CDN integration for downloads
  • Monitor your B2 storage usage through the Backblaze dashboard
