Where each one falls short

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

Comet Backup

  • Per-endpoint costs ($2/month per endpoint) can add up for large deployments with many protected machines
  • Advanced and Enterprise tiers with additional management capabilities are significantly more expensive than base tiers
  • Platform-specific features (SQL, MySQL, MongoDB, Microsoft 365) have separate per-unit pricing

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

Comet Backup: How much does Comet Backup cost?

Self-hosted plans start at $19/month (Starter) and go up to $99/month (Advanced), with cloud-hosted plans starting at $49/month (Professional). All plans charge $2 per endpoint per month for additional protected machines beyond the base license count.

Source
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.

Comet Backup: What is the price difference between self-hosted and cloud-hosted deployments?

Cloud-hosted plans start at $49/month (Professional) versus self-hosted which starts at $19/month (Starter). The main advantage of cloud-hosted is Comet manages the console infrastructure, though both models charge the same per-endpoint fees.

Source
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.

Comet Backup: Does Comet Backup charge for additional protected machines?

Yes, all plans charge $2 per endpoint per month beyond the licensed endpoints. For example, the Growth plan includes 2 self-hosted licenses, but each additional protected machine costs $2/month.

Source
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.
