The short version

  • Each has a real cost: 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.; StorageCraft ShadowProtect host-based backup requires Windows Server 2016 or above on the Hyper-V host, and desktop, client and Pro editions are not supported
  • They diverge on capability: Clumio covers Air-gapped backups, StorageCraft ShadowProtect covers Image-based backup.
  • 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.

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.

StorageCraft ShadowProtect

  • Host-based backup requires Windows Server 2016 or above on the Hyper-V host, and desktop, client and Pro editions are not supported
  • Host-based and agent-based backup are mutually exclusive installation modes in ShadowProtect 8.0; one machine cannot run both
  • Switching from agent-based to host-based requires a clean reinstall rather than an in-place upgrade
  • Host-based backups are not compatible with VirtualBoot
  • Granular file and folder recovery is not available for host-based backups; the whole backup must be restored to a .vhd or .vhdx first
  • Host-based backup jobs do not report status to ShadowControl
  • Advanced Verification in ImageManager 8.1 is not supported for host-based backups
  • All host-based backups go into a single folder by default, so separating them per VM means creating a separate backup job for each
  • Host-based licence keys are generated only through the Arcserve MSP portal
