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.; Redstor it is sold through the channel, so you cannot buy it direct and your price and support quality depend entirely on the partner you engage.
  • They diverge on capability: Clumio covers Air-gapped backups, Redstor covers InstantData.

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.

Redstor

  • It is sold through the channel, so you cannot buy it direct and your price and support quality depend entirely on the partner you engage.
  • Pricing is not published at all, and because partners resell it with their own margin, comparing quotes across MSPs is comparing partner markups rather than product cost.
  • The InstantData streaming advantage depends on network bandwidth to the data centre, so sites with poor connectivity see much less benefit than the demonstrations suggest.
  • Its footprint is concentrated in the UK, Europe and South Africa, so multinational organisations needing consistent coverage in North America or Asia will find the regional story uneven.
  • Feature depth for large enterprise virtual machine estates trails Veeam and Rubrik, so it fits small and medium client workloads rather than complex data centre recovery.

Answered from the vendors’ own pages

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.

Redstor: Can we buy Redstor directly?

Generally no. It is a channel product sold through managed service providers, so partner selection is part of the buying decision.

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.

Redstor: Are there restore or egress charges?

Redstor includes storage and recovery in the per-unit price rather than charging separately for egress, which is the opposite of the cloud-native backup vendors.

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.

Redstor: Where is data stored?

UK and regional data centres, selectable by tenant, which is the reason UK public sector and legal clients tend to shortlist it.
