Build unbreakable disaster recovery by replicating Backblaze B2 to Azure Blob Storage with automated cross-cloud sync.

Relying on a single cloud provider creates risk. Ransomware, service disruptions, or account compromise can jeopardize your entire backup strategy. The best defense is geographic and provider diversity—backing up your backups. Backblaze B2's affordability pairs perfectly with Azure's enterprise reliability. RcloneView automates cross-cloud replication, creating a resilient backup architecture that survives any single point of failure.

Why Cross-Cloud Backup Matters

Single-provider backups leave you exposed. RcloneView enables true defense-in-depth: back up to affordable Backblaze B2, then automatically replicate to Azure Blob Storage. If B2 becomes unavailable, your Azure replica maintains data availability. This multi-cloud approach dramatically reduces ransomware impact and vendor lock-in risk.

Configure Backblaze B2 and Azure Blob credentials

Setting Up B2 and Azure in RcloneView

RcloneView's setup wizard handles both services seamlessly. Configure Backblaze B2 with your application key, then add Azure Blob Storage with your storage account name and key. Both services appear as remote endpoints in your RcloneView dashboard.

Automated Redundancy at Scale

Create sync jobs that replicate B2 buckets to Azure containers on your schedule. RcloneView handles large datasets with bandwidth optimization and intelligent retry logic. Monitor replication progress in real-time and receive completion notifications automatically.
