The short version

  • Each has a real cost: Backblaze personal Backup is $99 a year billed annually, with no monthly option; 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.
  • They diverge on capability: Backblaze covers Unlimited backup, Nasuni covers Edge caching appliances.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Backblaze

  • Personal Backup is $99 a year billed annually, with no monthly option
  • Web restores are capped at 500GB per request
  • Forever version history is a Business tier add-on rather than included
  • Administrative controls and SSO are Business features
  • Backs up user data from a computer and attached drives, so NAS and server backup are not covered by the personal plan

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.

Answered from the vendors’ own pages

Backblaze: What is the pricing for Backblaze Personal Backup?

Backblaze Personal Backup costs $9/month on monthly billing or $8.25/month when billed annually, providing unlimited storage for a single computer.

Source
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.

Backblaze: What storage options does Backblaze B2 offer?

Backblaze B2 Cloud Storage is priced at $6/TB per month with a pay-as-you-go model, and is S3 compatible for flexible cloud storage.

Source
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.

Backblaze: Does Backblaze support Linux systems?

No. Backblaze does not support Linux operating systems, limiting it to Windows, macOS, and web access only.

Source
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.

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.
