The short version

  • Each has a real cost: Nasuni subscription is based on managed capacity, so cold data that would cost almost nothing in an archive tier keeps paying the full platform rate, and there is limited incentive structure to delete.; 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: Nasuni covers Edge caching appliances, Redstor covers InstantData.
  • 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.

Nasuni

  • Subscription is based on managed capacity, so cold data that would cost almost nothing in an archive tier keeps paying the full platform rate, and there is limited incentive structure to delete.
  • Every site needs an appliance, virtual or physical, which is a footprint and a patching obligation at locations that previously had only a file server or nothing.
  • A read that misses the local cache is fetched from object storage, so the first access to a cold large file is at cloud latency and users experience it as the system being slow at random.
  • Global file lock serialises access across regions, so genuinely collaborative editing of the same large files still involves waiting for another site to release the lock rather than merging.
  • The object storage underneath is your contract, so API transaction and egress charges from Azure or AWS land on your cloud bill and are not covered by the Nasuni subscription you were quoted against.

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

Nasuni: Do I still need a backup product?

That is the pitch: continuous versioning in object storage replaces the backup schedule for file data. Databases and virtual machines still need their own tooling.

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.

Nasuni: Who owns the storage account?

You do. Nasuni writes into object storage you contract for, which also means the cloud provider bills you directly for it.

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.

Nasuni: How fast is recovery of a whole site?

An appliance can be serving files within hours because data is pulled on demand, but performance stays degraded while the cache refills.

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.

Nasuni: Is pricing published?

No. Nasuni sells through quotes based on managed capacity and site count, so comparisons need a real proposal rather than a list price.
