The short version

  • Each has a real cost: Altaro VM Backup limited to small and medium-market businesses with up to 50 host servers; 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: Altaro VM Backup covers Augmented inline dedup, 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.

Altaro VM Backup

  • Limited to small and medium-market businesses with up to 50 host servers
  • Perpetual license model outdated compared to modern cloud-based backup solutions
  • Lacks enterprise-grade features for large-scale deployments
  • Offsite backup to cloud requires additional setup and configuration

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.
