Bottom line Editorial assessment

Is Carbonite cheaper than Backblaze?

From three computers up, yes, if your data fits: Carbonite Core is $287.99 a year ($24 a month) for up to 25 computers but only 250 GB in total. Backblaze charges $99 a computer a year with no storage limit, offers monthly billing and keeps a year of versions, but backs up no servers or NAS.

Quick verdict: For one or two computers Backblaze is cheaper; from three computers up, Carbonite Core’s flat $287.99 a year for up to 25 computers costs less, as long as everything fits in its 250 GB of shared storage (extra storage is $99 per 100 GB a year). Backblaze gives every computer unlimited storage and a year of version history, but backs up only Mac and Windows computers. Carbonite’s Power ($799.99 a year) and Ultimate ($1,299.99) bundles add Windows server backup, and it offers phone support on weekdays. Carbonite bills annually only.

Editorial assessment

How they actually differ

Both run a background agent that backs up each computer continuously and restores from a web console or by courier drive. The split is how they charge: Backblaze per computer, Carbonite per account.

Storage versus seats

Backblaze never limits storage, so a video editor’s 4 TB workstation costs the same $99 a year as a laptop. Carbonite Core covers up to 25 computers for one price but shares 250 GB across all of them. Estimate your team’s total data before comparing.

Servers and retention

Carbonite Power and Ultimate add Windows server backup (SQL, Exchange, Hyper-V, bare-metal images) to the same console. Backblaze Computer Backup has no server option. Backblaze keeps a year of versions; Carbonite keeps up to 12 versions over about three months and removes files deleted from a computer after 60 days.

Moving between them

Backup history does not move between services: none of the three imports another’s backups, so a switch means a fresh first backup on the new service while the old one keeps your version history until you cancel.

Editorial assessment

What this means for your team

  • Audit reports: both publish a SOC 2 report. Ask each vendor for the report under NDA before you sign; security reviews usually want the latest one.
  • Single sign-on: Backblaze includes it on Enterprise Control (add-on; OIDC, SAML not mentioned). Carbonite doesn’t document single sign-on with your own identity provider. If your team signs in through Okta, Microsoft Entra ID or Google, price the plan that includes SSO, not the entry plan.
  • Health data: Backblaze and Carbonite will sign a HIPAA business associate agreement (Carbonite: Core).
  • Working offline: Backblaze and Carbonite don’t document an offline mode. Details are in the Offline mode row above.
  • Where your data lives: Backblaze lets you choose US, EU. This matters for teams hiring across the EU, UK or Australia.
  • In the office: Backblaze: Backs up Mac/Windows computers and attached external drives; NAS and network drives are excluded, and large restores can be shipped on a USB drive. Carbonite: Backs up office NAS devices and external drives on all plans; Power/Ultimate add Windows servers (2008+) with cloud and onsite server backup targets.

Backblaze: worth knowing

  • RemoteBackblaze positions Business Backup for remote and distributed teams, deployed through MDM tools such as Jamf, Iru (Kandji), Addigy and Intune. source
  • OfficeOffice file servers and NAS cannot be protected with Computer Backup; Backblaze directs server/NAS backup to B2 Cloud Storage integrations. source
  • RemoteLarge restores can be shipped worldwide on an encrypted USB drive, prepared and shipped from the U.S. source
  • SecurityWith a private encryption key, Backblaze itself cannot access backed-up data, and a lost key cannot be recovered. source

Carbonite: worth knowing

  • OfficeNAS drives are included only on Safe Backup Pro plans, and a NAS whose path changes or whose selecting Windows admin stops signing in is dropped from the backup within 60 days. source
  • RemoteCourier Recovery (a shipped restore drive) is available only to Safe Backup Pro subscribers living in the United States. source
  • SecurityPrivate encryption key management is not available for Mac users. source
  • RemotePhone and email support is weekday business hours only (Eastern time), not 24/7. source
