Carbonite vs Zenko CloudServer

Carbonite

Zenko CloudServer

Carbonite

Pros

• Unlimited storage on personal plans regardless of data volume
• Long operating history and enterprise backing from OpenText
• Physical courier recovery option for restoring large data sets without a slow download
• 256-bit encryption and two-factor authentication for account security

Cons

• Personal plans cover only a single computer by default
• English-only language support
• File version history is capped at the 12 most recent versions rather than unlimited
• Business/server plans are priced and licensed separately, which can add up at scale

Zenko CloudServer

Pros

• Completely free and open source under a permissive Apache 2.0 license
• Full S3 API compatibility means minimal to no code changes for existing S3 applications
• Supports multiple cloud backends, reducing vendor lock-in
• Fast Docker-based deployment suited to local development and CI/CD
• Backed by an established storage vendor (Scality) with an active open-source community

Cons

• Requires self-hosting and infrastructure management, unlike a managed cloud storage service
• No official paid support tier included with the open-source project itself
• Best suited for developers comfortable with Docker and Node.js-based tooling
• Enterprise-grade features and support require Scality's separate commercial products

Carbonite

• Personal computer backup — Unlimited, automatic backup of a single home computer with optional external drive coverage.
• Small business workstation and server backup — Backup coverage for a defined number of business computers and servers, with expandable storage.
• Large-scale data recovery — Physical courier recovery service for restoring large volumes of backed-up data without a slow download.

Zenko CloudServer

• Local S3 development and testing — A development team runs CloudServer in Docker to test S3-dependent application code without connecting to a live AWS account.
• Multi-cloud storage abstraction — An enterprise uses CloudServer to present a single S3-style API in front of both Azure Blob Storage and Google Cloud Storage, avoiding vendor lock-in.
• On-premises S3-compatible storage — An organization with data sovereignty requirements deploys CloudServer on its own hardware to get S3-compatible storage without using a public cloud.
