📋 Assessment
💪 Strengths
- Unlimited backup at a flat rate: For $7/month (or $99/year), you get truly unlimited backup for one computer. This is a huge advantage for users with large local data—photographers, video editors, or anyone with terabytes of documents—because you never have to manage quotas or estimate your storage needs. The price is predictable and often far cheaper than per-GB services once you exceed a few hundred gigabytes.
- Transparent pricing: Backblaze is refreshingly upfront about costs. There are no tiered plans, no hidden fees, and no surprise overage charges for personal backup. The annual plan costs less than two months of many competitors' entry-level business plans. B2 pricing is also clearly listed on their website, with no minimum commitments, which builds trust in an industry known for opaque billing.
- S3-compatible B2 storage: B2's compatibility with Amazon S3 APIs is a critical feature for developers. You can use the AWS CLI, SDKs, or third-party tools like rclone and Duplicati without any special adaptation. This eliminates vendor lock-in and reduces the learning curve, while the lower egress fees (1 cent per GB vs. AWS's 9 cents) can save you significant money if you need to retrieve data frequently.
- Quarterly hard drive reliability reports: Backblaze publishes detailed statistics on hard drive failure rates from its own data centers. This transparency is a mark of confidence and provides valuable insights for both consumers and IT professionals. It also demonstrates a commitment to data integrity, giving users reassurance that their data is stored on hardware that's carefully monitored.
- Mobile and remote access: Even though backup is from one computer, you can access your files from any device via the Backblaze mobile app or web interface. You can browse, search, and download individual files or share links to others. This flexibility is handy for retrieving a document while you're away from your main computer.
⚠ Watch out for
- No native collaboration features: Backblaze is strictly a backup service. There are no shared folders, no multi-user permissions, and no activity feeds. If you need to collaborate with a team on files, you'll have to use another tool like Dropbox or Google Drive, which can be an extra cost and complexity. Even the Business plan doesn't offer collaboration—it just adds admin console and enforcement of encryption keys.
- Restoring large data is slow: Restoring your entire backup over the internet is time-consuming, especially if you have terabytes of data. The mail-in USB drive option (which costs a $99 refundable deposit) is a workaround, but it takes days to deliver and is not instant. For businesses that need quick recovery after a disaster, this could be a critical drawback.
- Variable costs on B2: While B2's egress fees are low, they are not zero. If you frequently download or access your stored objects (e.g., for processing or serving to users), costs can add up. Additionally, there are transaction charges for API operations. Users who are used to flat-rate backup might be caught off guard by a metered bill for B2.
- Personal backup is tied to one computer: Backblaze's unlimited plan covers a single computer. You cannot back up multiple machines under one personal plan without paying extra per computer. This is fine for individuals but a limitation for families or small businesses with multiple employee computers.
- No backup for network-attached storage (NAS) on personal plan: The personal plan doesn't support backing up NAS devices directly. Business plans can use B2 to back up NAS, but that requires more technical setup. If you rely on a NAS for home storage, you'll need to manually sync data to your computer first, which is a hassle.
🎯 Best for
Individual users and small businesses that want a reliable, no-nonsense, and cost-effective offsite backup solution for personal computers or S3-compatible object storage, without needing collaborative file-sharing features.
🚫 Who should skip
Organizations that rely on team collaboration, file sync across multiple devices, or granular access controls, as Backblaze focuses on backup and raw storage rather than a productivity suite.
📚 Learning curve
Minimal for personal backup—installation and initial setup take minutes, and the software runs automatically in the background. B2 has a moderate learning curve if you're configuring API integrations or S3-compatible tools, but basic uploads are straightforward.
🧑⚖️ Verdict
Backblaze is an excellent choice for individuals needing unlimited, affordable backup for a single computer, and for developers wanting S3-compatible storage at a low cost. However, teams looking for collaboration features or businesses needing rapid large-scale restores should look elsewhere. If yo

📋 Assessment
💪 Strengths
- Zero-knowledge encryption: Tresorit’s end-to-end encryption ensures that only you and your chosen recipients can decrypt files. Even Tresorit’s own servers host only ciphertext. This is a significant advantage over providers like Dropbox, which can access unencrypted data when legally compelled. For law firms, journalists, and whistleblowers, this is non-negotiable.
- Swiss jurisdiction: Files are hosted in data centers in Switzerland, a country with some of the world’s strongest data privacy laws. This means your data is protected by Swiss Federal Act on Data Protection (FADP), which is stricter than many national regulations. This legal layer is critical for European businesses navigating GDPR.
- Compliance certifications: Tresorit holds ISO 27001, HIPAA, and GDPR certifications, making it one of the few cloud storage services that can be used in healthcare and government sectors. The platform undergoes regular third-party audits, providing verified assurance that security controls are sound — not just marketing claims.
- Granular permission controls: Users can set individual access rights for each folder, such as view-only, comment, or full edit. You can also set link expiry dates and revoke access at any time. This granularity is essential for collaborative projects where external parties need limited access, reducing the risk of data leakage.
- Tresorit for Outlook and Gmail: The add-ins allow you to share files securely directly from your email client, automatically generating encrypted links with upload permissions. This streamlines workflows for professionals who handle sensitive attachments daily, eliminating the need to switch between apps.
⚠ Watch out for
- Cost: At $12 per month for 1TB (Personal) or $15 for 2TB (Business), Tresorit is significantly pricier than Dropbox Plus ($9.99 for 2TB) or Google Drive (with Workspace). The free tier is only a 30-day trial with limited storage (up to 3GB for 7 days). For individuals on a budget, the price may be a deterrent.
- Sync speed: Client-side encryption means every file must be encrypted and decrypted locally, which adds overhead. Syncing large files (e.g., 10GB video projects) can be noticeably slower than unencrypted services. In benchmark tests, Tresorit’s upload speeds are often 20-30% lower than Dropbox or Google Drive. For heavy media files, this becomes a practical limitation.
- Limited third-party integrations: While Tresorit supports Outlook, Gmail, and Microsoft Teams, it lacks the vast ecosystem that Google Drive and Dropbox have cultivated. There’s no native integration with tools like Slack, Salesforce, or Zapier. Users might have to rely on workarounds or third-party automation which is not straightforward.
- No smart sync: Unlike Dropbox’s Smart Sync or Google Drive’s Mirror, Tresorit does not offer a feature to keep files exclusively in the cloud and stream them on demand. All files are stored locally, consuming disk space. This is a significant drawback for users with limited internal storage, especially on laptops.
- User interface is dated: The desktop client and web dashboard are functional but feel less polished compared to modern cloud storage apps. The UI can be cluttered with nested options, and finding features like link settings or activity logs requires a few steps. For non-technical users, the learning curve is steeper than average.
🎯 Best for
Privacy-conscious professionals, legal and medical firms, and businesses that need legally compliant, end-to-end encrypted file storage and sharing.
🚫 Who should skip
Individuals looking for a cheap cloud drive or teams heavily reliant on deep integrations with Google Workspace or Microsoft 365 may find Tresorit restrictive or overpriced.
📚 Learning curve
Moderate — setup is simple, but understanding recovery keys, link security options, and zero-knowledge workflows takes some practice.
🧑⚖️ Verdict
Tresorit is a top-tier choice for professionals and organizations that must meet strict compliance standards or handle highly sensitive data. Its zero-knowledge encryption and Swiss hosting are unmatched, yet the premium price and lack of integrations will deter casual users. If you prioritize secur

❓ Frequently Asked Questions
Is the personal backup plan truly unlimited, or are there throttles or caps?
Backblaze's personal backup plan is genuinely unlimited for one computer's internal and external drives, with no per-GB caps. However, excessive bandwidth usage may be throttled, and they require backups to run at least once every 30 days to maintain the unlimited status.
How does Backblaze B2 pricing work, and are there any egress fees?
B2 charges $6 per TB per month for storage, and you pay for transactions and egress bandwidth. Egress (downloading data) costs $0.01 per GB after the first 3 GB per day free, so heavy downloads can add up unexpectedly.
Can I restore files from my mobile device?
Yes, Backblaze's mobile app lets you browse, download, and share files from your backup, but it doesn't do a full system restore. For large restores, you can request a USB drive by mail for a refundable fee.
How long does Backblaze keep deleted or old versions of my files?
By default, Backblaze keeps deleted and changed file versions for 30 days. You can opt to extend this to 1 year or forever for an additional cost per year, which is useful for long-term versioning.
