Uncover the hidden fees in typical cloud archive models and discover how a predictable, S3-compatible alternative eliminates budget surprises for Cohesity users.

For enterprises using Cohesity, archiving data to the cloud is a standard practice for long-term retention and cost management. However, the apparent low per-gigabyte price of traditional cloud storage often hides substantial variable costs. Egress fees for data retrieval and API charges for access can cause the total cost of ownership (TCO) to skyrocket, making budget forecasting nearly impossible. A 2025 study revealed that 95% of large organizations have been hit with surprise cloud fees. This article explores the hidden factors driving up Cohesity cloud archive pricing and presents a cost-effective, S3-compatible storage alternative designed for predictability and performance, helping you reduce expenses by up to 80%.

Key Takeaways

  • Eliminate unpredictable Cohesity cloud archive costs by choosing an S3-compatible storage provider with zero egress fees and API charges, reducing TCO by up to 80%.
  • Strengthen ransomware protection for your Cohesity backups by using immutable storage with S3 Object Lock, which makes data unchangeable and guarantees recoverability.
  • Improve recovery performance with an "always-hot" storage architecture that provides instant access to archived data without the delays or retrieval fees common to tiered cold storage.

Identify Hidden Fees in Your Cloud Archive Tier

The primary challenge with Cohesity cloud archive pricing isn't the advertised storage rate; it's the unpredictable operational costs. Egress fees, charged any time you retrieve data, can surpass the cost of storage by 3-5x in data-intensive workloads. A recent survey found 55% of IT leaders see egress costs as the biggest barrier to switching providers.

Additionally, frequent API calls made by Cohesity to manage, index, and retrieve archived data can accumulate into a significant monthly expense. These variable charges make accurate budget forecasting a difficult task for any IT department. Organizations report savings of 60-80% simply by eliminating these fees.

Understanding your total cost requires looking beyond the per-terabyte price and analyzing your data access patterns. This deeper analysis reveals the true financial impact of your current S3-compatible storage solution.

Achieve Predictable Cloud Costs with a Transparent Model

A predictable pricing model is the foundation for effective budget management. Impossible Cloud offers S3-compatible object storage that is cost-efficient by design, eliminating the variables that inflate traditional cloud bills. Our model includes zero egress fees, zero API call charges, and no minimum storage duration requirements.

This approach provides complete cost transparency, allowing you to forecast your expenses with 100% accuracy. You pay only for the storage you use, resulting in up to 80% lower TCO compared to hyperscaler alternatives. This financial predictability empowers you to scale your Cohesity archives without fear of unexpected penalties. For a clear financial picture, explore our guide to predictable cloud billing.

Strengthen Ransomware Defense with Immutable Storage

Ransomware attacks increasingly target backup infrastructure, making immutable storage a critical defense layer. In 2025, 76% of all ransomware attacks involved data exfiltration before encryption, making data recovery the last line of defense. Impossible Cloud's S3-compatible storage includes Immutable Storage via Object Lock, a non-negotiable feature for modern data protection.

Here is how Object Lock enhances your Cohesity archive security:

  • It creates a WORM (Write-Once-Read-Many) state, preventing data from being altered or deleted for a defined retention period.
  • This protection applies even to privileged accounts, neutralizing threats from compromised credentials.
  • It helps meet stringent compliance requirements for data integrity in regulated industries like finance and healthcare.
  • Immutable backups render ransomware encryption attempts useless, ensuring your data is always recoverable.

By integrating this feature, you transform your archive from a simple storage tier into a secure vault for ransomware protection.

Improve Recovery Times with an Always-Hot Architecture

Traditional cloud archives often rely on complex storage tiers, moving data to "cold" or "glacier" layers to reduce costs. While cheaper for storage, retrieving data from these tiers can take hours and incurs hefty retrieval fees, negatively impacting your Recovery Time Objectives (RTOs). This delay is unacceptable during a critical recovery event.

Impossible Cloud utilizes an "Always-Hot" object storage model. All data in your Cohesity archive is immediately accessible, with no restore delays or retrieval fees. This architecture simplifies operations, eliminates brittle lifecycle policies, and delivers up to 20% faster backup performance. An always-hot model ensures your third-party tools remain stable and your data is ready for recovery at a moment's notice, a key benefit when you replace tape with cloud.

Ensure Seamless Cohesity Integration with Full S3 Compatibility

For an alternative storage tier to be effective, it must integrate flawlessly with your existing workflows. Impossible Cloud offers full S3 API compatibility, ensuring it works as a drop-in replacement for your Cohesity CloudArchive or CloudArchive Direct targets. This compatibility protects your past investments and minimizes migration risk.

The migration process is straightforward:

  1. Create a new external S3-compatible target in your Cohesity dashboard.
  2. Enter the Impossible Cloud service endpoint and credentials.
  3. Update your archival policies to point to the new, cost-efficient target.
  4. Test your restores to validate the configuration and performance.

Because the S3 API is the de-facto standard, no code rewrites or complex reconfigurations are needed. This seamless transition allows you to start realizing cost savings in a matter of hours, not weeks, which is a core advantage for any Veeam Capacity Tier user as well.

Build High-Margin Backup Services for the Channel

For Managed Service Providers (MSPs), unpredictable costs directly erode profit margins. Offering Backup-as-a-Service (BaaS) using a hyperscaler backend means passing on volatile egress and API fees, making it difficult to provide competitive, fixed-rate pricing. This is a major challenge for MSPs using solutions like Rubrik Cloud Vault.

Impossible Cloud's partner-centric model is predictable by design. With no egress or API fees, MSPs can set BaaS and DRaaS prices with confidence, protecting margins by over 25%. Our platform includes a multi-tenant console, automation via API/CLI, and full whitelabeling capabilities. This allows you to stop reselling a vendor's service and start owning your own branded, high-margin cloud storage offering. This is especially powerful when paired with tools like Commvault Metallic for comprehensive data protection.

FAQ

What is the main driver of high Cohesity cloud archive pricing?

The main drivers are not the base storage costs, but the variable, unpredictable fees. Egress fees (for data retrieval) and API call charges can dramatically increase your monthly bill, often exceeding the cost of storage itself and making accurate budgeting impossible.

How does Impossible Cloud eliminate vendor lock-in?
