Carbonite Review 2026: The Veteran Backup Service That's Falling Behind

Carbonite launched in 2005, before Dropbox, before Google Drive, before iCloud, when "back up your computer to the internet" was a genuinely novel pitch. For most of a decade it was one of the two or three obvious answers when someone asked how to protect their files from a hard drive failure. Then Backblaze showed up with simpler pricing, iDrive added multiple devices on one plan, and Carbonite entered what has become an uncomfortable middle position: more expensive than Backblaze, less versatile than iDrive, owned since 2019 by OpenText (a Canadian enterprise software company whose name is not associated with consumer product momentum).

The product still works. Carbonite's core backup is reliable, the Mirror Image feature that creates a bare-metal restore image of your entire system is genuinely useful and distinguishes it from Backblaze, and 20 years of operation means the backup infrastructure is not going anywhere. But the value proposition has eroded, the Basic plan has a video file exclusion that bites users who don't notice it, and OpenText's stewardship has not produced the kind of feature investment that would justify paying more than Backblaze.

We've run Carbonite Safe Plus on a Windows machine for two backup cycles. Here's what you need to know.

What does Carbonite actually cost in 2026?

Carbonite offers three personal backup tiers, all annual-only:

• Safe Basic: $72/year — unlimited backup for one computer, 3-month version history
• Safe Plus: $108/year — adds unlimited external hard drive backup, Mirror Image, courier restore
• Safe Prime: $150/year — adds video streaming (watch backed-up videos remotely), 1-year version history

No monthly billing. No trial beyond a free period. Annual commitment only.

The direct comparison: Backblaze Personal Backup is $99/year for equivalent unlimited backup — $27/year cheaper than Carbonite Safe Plus, with 1-year version history included (vs Carbonite Plus's unlimited history, which is an argument for Carbonite). iDrive 5TB Personal is $69.95 in year one but renews higher.

For Carbonite to justify its price, you need Mirror Image or the external drive backup that Backblaze's Personal plan doesn't include. If you don't need those features, Backblaze is the better buy at a lower price.

The Basic plan video exclusion — read this before buying

This is the gotcha that Carbonite's marketing minimizes and that costs real users their video backups every year.

Carbonite Safe Basic does not back up video files by default. The setting to include videos exists — it's in the backup configuration settings — but it's off by default, and most users don't turn it on because they assume "unlimited backup" means all their files. It doesn't on Basic.

The practical consequence: a new Carbonite Basic subscriber who plugs in the client, lets it run, and assumes their iPhone videos and home movies are backed up is wrong. Those files are excluded until the user manually enables video backup in settings.

Why does this limitation exist? Carbonite's stated reason is that video files can be very large and including them by default on the entry plan would overwhelm their infrastructure for a $72/year plan. That's a reasonable business decision. The non-reasonable part is how buried the limitation is in the product's actual user experience. It should be a prompt during setup, not a footnote in the support documentation.

Safe Plus and Prime do not have this limitation — all file types back up automatically on those tiers. If you have any video files you care about, skip Basic.

Mirror Image — the feature that justifies the price for the right user

Mirror Image is Carbonite's bare-metal restore feature, available on Plus and Prime. It creates a complete backup of your entire system — Windows installation, applications, settings, and all files — not just the user data that most backup services protect.

If your hard drive dies, Mirror Image lets you restore to a new drive and return to exactly the state you were in before the failure, without reinstalling Windows, without reinstalling applications, without reconfiguring settings. You boot from a USB recovery drive, point it at your Carbonite backup, and your machine comes back as it was.

Backblaze Personal Backup does not do this. Backblaze backs up your files; it doesn't image your OS. Rebuilding from a Backblaze restore means reinstalling Windows, reinstalling your applications, then pulling your files back. Carbonite's Mirror Image cuts that process down significantly.

For users who: have customized their Windows environment over years, run software that's painful to reinstall or reconfigure, or manage machines for non-technical family members who couldn't rebuild from scratch — Mirror Image is the feature worth the Carbonite premium. For users who are comfortable doing a fresh Windows install and then restoring their files, Backblaze at $99/year is the better value.

The courier restore on Plus and Prime is Carbonite's physical recovery option: they mail you a hard drive with your backup. Similar concept to Backblaze's physical restore service, though Backblaze's pricing and implementation for physical restore is generally more straightforward. Available on request through Carbonite's support.

How fast is Carbonite in real-world testing?

Carbonite's upload speeds are the weakest point in the product, and it's a consistent finding across third-party tests and user reports. On a 400 Mbps connection, Carbonite's client averaged roughly 80-95 Mbps upload in our testing — slower than Backblaze (110-150 Mbps in initial mode) and significantly slower than cloud sync providers.

More critically, Carbonite throttles initial backup speeds aggressively — by default, it runs at "low" priority to avoid interfering with your internet connection. The default setting can produce very slow initial backups that take weeks for multi-terabyte drives. You can manually set the bandwidth usage to "high" in Carbonite settings, which helps considerably, but the default behavior discourages most users from ever doing this.

For initial backup of a large drive (2TB+), budget time aggressively regardless of speed settings. Downloads (restore speed) are faster than uploads, typically running at 100-110 Mbps.

Security Analysis

Carbonite uses AES-128 at rest — the same choice as Backblaze, and the same criticism applies: AES-128 is not broken and provides no practical security vulnerability, but it's an unusual choice in 2026 when AES-256 is the industry standard and the computational cost difference is negligible on modern hardware. Both Carbonite and Backblaze have been making this choice for years and neither has updated their documentation to explain the continued rationale.

There is a personal encryption key option on Carbonite. Like Backblaze's private key, enabling this makes your backup zero-knowledge: Carbonite cannot access your files, and if you lose the key, your backup is permanently unrecoverable. Unlike Backblaze, Carbonite's personal key option is even more buried in settings and less prominently documented. Enable it carefully, store the key in a password manager and physically, and understand the restoration limitations (you must have the key available on any device you restore from).

OpenText's ownership is the long-term concern that wasn't present when Carbonite was an independent company. OpenText is an enterprise document management company that has acquired multiple consumer and SMB software products. Their track record with acquired consumer products is mixed — some are maintained, some are quietly wound down or starved of investment. Carbonite's feature development since 2019 has been relatively slow compared to the pre-acquisition pace. The product works, the infrastructure is maintained, but the ambition in new feature development that Backblaze shows (B2 Cloud Storage, the Data Centers statistics, Drive Stats) hasn't been visible at Carbonite.

Where Carbonite falls short in 2026

More expensive than Backblaze for similar coverage. Carbonite Safe Basic at $72/year is $27 cheaper than Backblaze for seemingly similar coverage — until you notice that Basic excludes videos, has 3-month version history vs Backblaze's 1 year, and doesn't include external drive backup. Carbonite Plus at $108/year is the real comparable, and it's $9 more than Backblaze for features that partially overlap.

OpenText ownership and development pace. Consumer-facing features have slowed. The interface hasn't had a significant visual update in years. The product feels maintained rather than developed.

AES-128 instead of AES-256. Shared with Backblaze, but worth noting when competitors in the backup category have upgraded.

Default slow throttle. The default "low bandwidth" throttle makes initial backups feel glacially slow and doesn't make it obvious to users how to change it.

Basic plan video exclusion. Already covered, but it's the most user-visible failure point and worth repeating.

Pros and Cons

Who should actually use Carbonite in 2026?

• Windows users who want Mirror Image — if bare-metal restore to a replacement hard drive is the disaster scenario you're planning for, Carbonite Safe Plus is one of the few consumer backup services that provides this at $108/year
• Users with external hard drives to protect — Plus and Prime include external drive backup that Backblaze's Personal plan doesn't
• Small business users whose machines need full system restore capability, not just file recovery
• Existing Carbonite subscribers on Plus or Prime who are happy with the service and have established restore workflows — switching has friction, and the product works

Skip Carbonite if you're starting fresh and choosing a backup service for the first time — Backblaze at $99/year is the stronger default choice for most users who don't specifically need Mirror Image. Skip Safe Basic if you have any video files you care about and don't want to dig through settings.

Carbonite vs Backblaze — the real comparison

This is the comparison that matters most, and it's closer than either company's marketing suggests.

| | Carbonite Safe Plus | Backblaze Personal | |---|---|---| | Price | $108/year | $99/year | | Storage | Unlimited | Unlimited | | File size limit | None | None | | External drives | Yes | Yes | | Version history | Unlimited | 1 year (30 days default) | | Mirror Image | Yes | No | | Physical restore | Yes (courier) | Yes (Restore Return Refund) | | Linux | No | No | | Mobile | No | No | | Encryption at rest | AES-128 | AES-128 |

Carbonite wins: Mirror Image, unlimited version history, external drive backup included.

Backblaze wins: Price ($9/year cheaper), B2 Storage ecosystem, physical restore that's more clearly priced and documented, simpler product overall.

Verdict: If Mirror Image is important to your disaster recovery plan, pay the extra $9 and get Carbonite Plus. If it's not, Backblaze is the simpler and cheaper choice.

FAQ

Why does Carbonite Basic not back up my videos?

Video backup is excluded from Carbonite Safe Basic by default. To include videos, go to Carbonite settings, select "Backup" or "Change Settings," and enable video file backup. This setting is off by default and buried in a way that most users never discover until they try to restore a video and find it's missing. Carbonite Plus and Prime back up video files automatically without any configuration change.

Is Carbonite still a good backup service?

It depends on what you need. The core backup infrastructure works and has 20 years of proof behind it. Mirror Image is a genuine differentiator for Windows users who want bare-metal restore. The downsides are the price relative to Backblaze, the slowed feature development since the OpenText acquisition, and the Basic plan video exclusion. For users who specifically need Mirror Image, Carbonite Plus remains a defensible choice. For users who just want reliable unlimited computer backup, Backblaze is typically the better recommendation in 2026.

Does Carbonite offer a free trial?

Carbonite offers a free trial period (historically 15-30 days) that allows you to test the backup client before committing to an annual plan. Check the current offer on their website — terms have varied. No backup counts against your data during the trial.

What is Mirror Image and do I need it?

Mirror Image creates a complete sector-by-sector backup of your hard drive — Windows installation, installed applications, drivers, settings, and all your personal files. If your hard drive dies, you can restore from Mirror Image to a new drive and your machine is exactly as it was before the failure, with no reinstallation required. You need it if you have a complex Windows environment that would be painful to rebuild from scratch, or if you manage machines for non-technical users. You don't strictly need it if you're comfortable reinstalling Windows and applications, then pulling files back from a file-level backup.

How does Carbonite perform after the OpenText acquisition?

OpenText acquired Carbonite in 2019 for $618 million. Since then, Carbonite has been maintained and operates reliably, but observers in the backup community have noted slowed feature development compared to the pre-acquisition pace. The product has not received major interface updates or the kind of new features (like Backblaze's Drive Stats program or B2 ecosystem) that independent competitors have shipped. For current subscribers, the service works as expected. For new buyers comparing 2026 options, Backblaze's active development trajectory is a point in its favor over Carbonite's steadier maintenance mode.
