Backblaze vs Nextcloud

Backblaze is a publicly traded storage company from San Mateo, California, founded in 2007, that runs its own data centers and sells two products. Computer Backup continuously backs up an entire Mac or Windows PC, including attached external drives, for a flat monthly price with no data cap. B2 Cloud Storage is S3-compatible object storage priced per terabyte, positioned as a much cheaper alternative to Amazon S3, Google Cloud Storage and Azure Blob Storage.

Computer Backup offers version history, restores through the web and the app, and the option to have data shipped on a USB drive. B2 includes free egress up to three times the data stored each month, free transfer through partners such as Cloudflare, object lock for immutable, ransomware-resistant backups, and integrations with tools like Veeam, Synology, QNAP, rclone and media asset managers. The first 10 GB of B2 storage is free, and billing beyond that is simple and predictable.

Backblaze suits individuals and creatives who want set-and-forget workstation backup, and developers or IT teams storing backups, media archives and app uploads cheaply. It is not a sync or collaboration tool like Dropbox, it offers far fewer regions and services than AWS, and very large Computer Backup restores can be slow. Against Wasabi it competes on egress terms and ecosystem, and against IDrive on simplicity. The company is also known for publishing quarterly hard drive reliability statistics from its own fleet.

Nextcloud is an open-source, self-hosted collaboration platform developed by Nextcloud GmbH in Stuttgart, Germany. It started in 2016 as a fork of ownCloud led by Frank Karlitschek and has become the best-known alternative to Google Workspace and Microsoft 365 for organizations that want to keep their data on their own infrastructure.

The core is file sync and share with desktop and mobile clients, versioning, sharing links and fine-grained permissions. Nextcloud Hub adds online office editing through Nextcloud Office (based on Collabora) or ONLYOFFICE, Talk for chat and video calls, calendar, contacts, mail, Deck boards and groupware, plus a large app store. Security features include server-side and end-to-end encryption, two-factor authentication and LDAP or SAML integration, and Nextcloud Assistant offers AI features that can run on local models. The community edition is free; Nextcloud Enterprise is a subscription that adds support, long-term maintenance and enterprise features.

Nextcloud fits governments, universities, healthcare and companies with data sovereignty or compliance requirements, and technically skilled individuals running a home server. The cost is operational: someone must install, tune, update and back it up, and the interface is less polished than Google's or Microsoft's. ownCloud and Seafile are comparable self-hosted options, while managed Nextcloud hosting from partners can reduce the maintenance burden.
