Backblaze vs Tresorit

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.

Tresorit is an end-to-end encrypted cloud storage and file sharing service founded in Budapest, Hungary, in 2011 and majority-owned by Swiss Post since 2021. Files are encrypted on the user's device before upload, so Tresorit cannot read them, and data is stored in Microsoft Azure data centers in the region the customer chooses. It targets organizations whose documents are confidential by nature, such as law firms, healthcare providers, financial advisers and executives.

Beyond desktop and mobile sync, Tresorit offers encrypted share links with passwords, expiry and download limits, file requests, encrypted email attachments through an Outlook add-in, and Tresorit eSign for signatures. Admins get policy controls, remote wipe, activity and audit logs, SSO and Active Directory integration. Plans include a personal tier, business tiers priced per user with a minimum number of seats, and enterprise agreements.

Tresorit fits regulated or confidentiality-focused teams that need strong encryption they can prove to clients and auditors, and European organizations sensitive to data jurisdiction. It costs more than mainstream storage, sync and previews can feel slower, and integrations with office suites are fewer. Proton Drive offers end-to-end encryption at lower cost but fewer business controls, Sync.com is a budget encrypted option, and Box or Microsoft OneDrive suit teams prioritizing collaboration and integrations over zero-knowledge security.
