The short version

  • Each has a real cost: Carbonite upload speeds are significantly slower than competitors due to lack of block-level algorithms and multithreading; 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: Carbonite covers Automatic 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.

Carbonite

  • Upload speeds are significantly slower than competitors due to lack of block-level algorithms and multithreading
  • Bandwidth throttling control is limited, preventing users from managing full bandwidth allocation
  • Mobile apps and web access are more limited than sync-first services like Dropbox or Google Drive
  • Uses AES-128 encryption instead of industry-standard AES-256
  • Hybrid backup support is restricted to professional plans, unavailable for personal users

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

Carbonite: Does Carbonite offer unlimited storage?

Yes, Carbonite's personal plans (Safe Basic through Safe Server Ultimate) offer unlimited cloud storage, though business plans have tiered storage starting at 250 GB.

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.

Carbonite: What is Carbonite's pricing?

Personal plans range from $4.91 to $83.33 per month with annual billing. Business plans start around $50-$75 per endpoint annually, with volume discounts available for multi-year contracts.

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.

Carbonite: How fast are Carbonite's upload speeds?

Carbonite's upload speeds are notably slow and are consistently identified as the platform's main weakness. The lack of block-level algorithms and multithreading contributes to these speed limitations.

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.

Carbonite: What encryption does Carbonite use?

Carbonite uses AES-128 encryption at rest, which is an unusual choice in 2026 when AES-256 is the industry standard.

Source
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.
