The short version

  • Each has a real cost: Carbonite upload speeds are significantly slower than competitors due to lack of block-level algorithms and multithreading; Clumio restore is charged at $0.040 per GiB plus data transfer out, so recovering a hundred terabytes in an incident costs thousands of dollars on top of the storage fee, a bill nobody budgets for.
  • They diverge on capability: Carbonite covers Automatic backup, Clumio covers Air-gapped backups.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Carbonite

  • Upload speeds are significantly slower than competitors due to lack of block-level algorithms and multithreading
  • Bandwidth throttling control is limited, preventing users from managing full bandwidth allocation
  • Mobile apps and web access are more limited than sync-first services like Dropbox or Google Drive
  • Uses AES-128 encryption instead of industry-standard AES-256
  • Hybrid backup support is restricted to professional plans, unavailable for personal users

Clumio

  • Restore is charged at $0.040 per GiB plus data transfer out, so recovering a hundred terabytes in an incident costs thousands of dollars on top of the storage fee, a bill nobody budgets for.
  • Per-object charges of $1.50 per million managed objects per month mean estates with billions of small objects pay far more than a per-gigabyte estimate suggests.
  • The archive tier is cheaper to store but restores begin only after 24 to 48 hours, which is incompatible with most recovery time objectives, and early deletion inside six months incurs a fee.
  • It is an AWS product; Azure workloads are on the roadmap rather than shipping, so multi-cloud organisations still need a second backup platform.
  • The Commvault acquisition means Clumio now overlaps with Commvault own cloud protection, and buyers should ask directly how the two portfolios converge before signing multi-year terms.

Clumio: What does a restore cost?

$0.040 per GiB for instant access, $0.09 per GiB retrieved from archive, $0.025 per 1,000 API requests, plus AWS data transfer out. Model this before an incident.

Carbonite: What is Carbonite's pricing?

Personal plans range from $4.91 to $83.33 per month with annual billing. Business plans start around $50-$75 per endpoint annually, with volume discounts available for multi-year contracts.

Source
Clumio: Does it support Azure?

Not yet. Azure workloads are listed as on the roadmap. Today it is AWS, with some Google Cloud Storage coverage.

Carbonite: How fast are Carbonite's upload speeds?

Carbonite's upload speeds are notably slow and are consistently identified as the platform's main weakness. The lack of block-level algorithms and multithreading contributes to these speed limitations.

Source
Clumio: Is it still Clumio after the Commvault acquisition?

Yes, sold as Clumio by Commvault with its own pricing page and product line, but ask about portfolio convergence on a multi-year deal.

Carbonite: What encryption does Carbonite use?

Carbonite uses AES-128 encryption at rest, which is an unusual choice in 2026 when AES-256 is the industry standard.
