Where each one falls short

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

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.

Spanning Backup

  • No pricing published; requires quote request
  • Pricing is customizable based on data volume and service changes
