Understanding Rubrik's Archival Strategy and S3 Targets

Rubrik's data management platform is designed to simplify backup, recovery, and archival, providing a unified approach to data protection. A key feature is its ability to offload older, less frequently accessed data to archival locations, with S3-compatible object storage being a primary choice. This strategy allows organizations to free up expensive primary storage on their Rubrik appliances while maintaining data accessibility for compliance, legal hold, or long-term retention requirements. Rubrik supports various archival locations, including public cloud S3 and private cloud S3 object stores.

When configuring an S3 archive target with Rubrik, the process typically involves defining an archive location within the Rubrik interface, specifying S3-compatible object storage as the vendor, and providing access credentials along with the bucket endpoint URL. This integration uses the S3 API, allowing Rubrik to manage the lifecycle of backup data, including copying data to the archive and retrieving it when necessary. The flexibility of S3 compatibility means that existing tools and workflows can often integrate seamlessly, reducing the need for extensive re-architecture.

The benefits of using S3 for Rubrik archives are clear: scalability to handle vast amounts of data, durability for long-term preservation, and the ability to benefit from cloud economics. However, the 'cloud economics' part often comes with a caveat when dealing with hyperscalers. While the initial storage cost per gigabyte might appear low, the total cost of ownership can escalate rapidly due to additional charges that are not always immediately apparent. This is particularly true for data that, while archived, may still require occasional access or movement.

The Hidden Costs of Hyperscaler S3 for Long-Term Archive

While hyperscale cloud providers like AWS, Azure, and Google Cloud Platform (GCP) offer S3-compatible storage, their pricing models for archival tiers often introduce complexities and hidden costs that can significantly impact an organization's budget. The most significant of these are egress fees, which are charges incurred when data is moved out of the cloud provider's network. For backup and disaster recovery scenarios, where large volumes of data might need to be restored, these fees can quickly become prohibitive. For instance, AWS charges around $0.09/GB for egress, Azure around $0.087/GB, and GCP can range from $0.08 to $0.12/GB for inter-continental egress.

Beyond egress, hyperscalers often employ tiered storage models (e.g., AWS S3 Glacier Deep Archive, Azure Blob Archive, GCP Archive Storage) that promise ultra-low storage costs. However, these tiers come with their own set of hidden expenses, including data retrieval fees and minimum storage durations. For example, retrieving data from AWS S3 Glacier Deep Archive can incur a cost of $0.0025/GB, Azure Blob Archive $0.02/GB, and GCP Archive Storage $0.05/GB. These retrieval costs, combined with longer access times (sometimes hours for deep archive tiers), can make rapid data recovery expensive and operationally challenging.

Furthermore, API call charges, though seemingly small per operation, can accumulate substantially for high-object-count workloads typical of backup environments. Each read, write, or list operation against an S3 bucket incurs a small fee, and over time, these transactional costs add up, contributing to an unpredictable monthly bill. A 2025 Forrester report highlighted that while public cloud storage adoption is driven by business resilience, security concerns and rising costs persist, with many enterprises seeking to rein in expenses and manage growing infrastructure complexity. This intricate web of charges makes accurate cost forecasting nearly impossible, undermining the financial predictability that MSPs and enterprises require.

Essential Criteria for Evaluating S3 Archive Targets

When evaluating an S3 archive target for Rubrik, a clear set of criteria is essential to ensure both cost-effectiveness and operational efficiency. The primary goal is to find a solution that offers predictable pricing, robust security, and reliable performance without the hidden complexities often found in hyperscaler offerings. This is particularly important for MSPs who need to maintain healthy margins and provide transparent billing to their clients.

Cost Predictability: The most significant factor is the elimination of variable costs. Solutions that offer flat-rate pricing without egress fees, API call charges, or complex retrieval tiers provide greater budget certainty. This allows for accurate forecasting and avoids the 'bill shock' associated with unexpected data transfers or access patterns. For MSPs, predictable costs translate directly into predictable margins, enabling them to offer competitive and stable pricing to their customers.

Performance for Restores: While archiving implies infrequent access, the ability to quickly restore data when needed is paramount for disaster recovery. An optimal S3 archive target should offer 'Always-Hot' access, meaning all data is immediately available without lengthy rehydration delays or additional retrieval fees. This ensures that RTO (Recovery Time Objective) targets can be met, even for archived data.

Data Control and Security: Maintaining full control over data location and access is critical. This includes strong encryption for data in transit and at rest, along with robust Identity and Access Management (IAM) capabilities. Immutable Storage with Object Lock is an essential feature for ransomware protection, ensuring that backup data cannot be altered or deleted for a specified retention period. Furthermore, certifications like SOC 2 Type II, ISO 27001, and PCI DSS provide independent validation of a provider's security posture and commitment to data protection.

Here's a comparison of key evaluation criteria for S3 archive targets:

The MSP Imperative: Predictable Cloud Storage for Backup & DR

For Managed Service Providers (MSPs), the economics of cloud storage are not just about cost savings, but about predictable margins and the ability to deliver reliable, value-driven services to their clients. When using cloud storage as a Rubrik S3 archive target, unpredictable hyperscaler costs can directly erode an MSP's profitability. Egress fees, in particular, pose a significant challenge, as they are often difficult to forecast and pass on transparently to clients, leading to billing disputes and strained relationships. A 2025 report by DeskDay highlights that margins and profitability are becoming increasingly important for MSPs, who must consider not just what they charge, but what margin they get after delivering and operating the service.

Ransomware protection is another critical concern for MSPs. Implementing a 3-2-1 backup rule, which includes an offsite, immutable copy, is a best practice for cyber resilience. S3-compatible object storage with Object Lock functionality provides the necessary immutability to safeguard backups against ransomware attacks, ensuring that even if primary systems are compromised, a clean recovery point is available. However, if retrieving these immutable backups from a hyperscaler incurs significant egress fees, the financial burden of recovery can be crippling for both the MSP and their client.

Operational simplicity is also key for MSPs. Managing complex storage tiers, understanding intricate pricing calculators, and dealing with varying API call costs across different hyperscalers adds significant overhead. MSPs need solutions that are easy to integrate, manage, and scale, allowing them to focus on delivering proactive services rather than troubleshooting billing discrepancies or navigating complex cloud portals. The ability to offer a branded cloud storage service, backed by a predictable cost model, empowers MSPs to 'stop reselling and start owning' their cloud offerings, enhancing their market position and client loyalty.
