Backblaze vs Google Drive: Privacy Comparison
This in-depth comparison weighs Backblaze against Google Drive along six decisive privacy dimensions: how data is collected, how encryption is implemented, how data is shared with third parties, what privacy controls users get, how transparent each service is, and what their historical track record looks like. The two cover much the same ground, yet they handle user privacy in very different ways. What our review shows is that Backblaze delivers a clearly stronger privacy experience on balance, even though each option has its own relative pluses and minuses that are worth examining closely.
Who Wins, and Why
The most useful starting point is the overall tally and the single dimension that decided it. Across the six privacy dimensions we score, Backblaze finishes ahead of Google Drive, 54/60 to 38/60. That total reflects a side-by-side review in which one service is consistently the more privacy-respecting choice, even though both cover the same functional ground.
Most of the distance between these services opens up on Encryption: Backblaze 7/10 versus Google Drive 4/10. On Data Collection the margin nearly vanishes: Backblaze 10/10 against Google Drive 8/10. Continue for the full reasoning behind each category score.
What Gets Collected
Every privacy assessment starts with data collection. How much a service gathers, stores, and processes about its users is what ultimately drives the privacy risk of using it. Backblaze takes a leaner approach here, capturing only the data strictly required to make the service work. Its rival pulls in a wider net of information -- behavioral patterns, device identifiers, and usage analytics that go well past what the core features actually need. Our marks were Backblaze 10/10 and Google Drive 8/10 in this area. What separates them is not merely how much is gathered but why it is gathered and whether it is truly needed.
How Strong Is the Encryption
Encryption protects user data both in transit and at rest, and the implementation quality varies dramatically between services. Backblaze implements stronger encryption measures, including more robust protocols for data in transit and better protection for stored data. The specific encryption implementations differ in their coverage (which data is encrypted), their strength (which algorithms and key lengths are used), and whether end-to-end encryption is employed (preventing even the service provider from accessing user content). Backblaze scored 7/10 while Google Drive scored 4/10 for encryption.
Sharing Data With Outside Parties
A service's willingness to hand data to outside parties is a make-or-break privacy factor. That covers advertising networks, analytics providers, business partners, and what happens when governments come asking. Backblaze keeps a tighter lid on who can reach user data. These sharing habits shape security as much as privacy, since every extra party granted access becomes one more way a breach could happen. Scores: Backblaze 8/10, Google Drive 5/10.
User Privacy Controls
The availability and effectiveness of user-facing privacy controls determine how much agency individuals have over their own data. This includes settings for data collection opt-out, download and deletion capabilities, granular permission controls, and the ease with which users can exercise their rights under applicable privacy regulations. Backblaze provides more comprehensive and accessible privacy controls. Scores: Backblaze 9/10, Google Drive 6/10.
Transparency
At its core, transparency is about how clearly a service tells users what happens to their data. That means how understandable the privacy policy is, whether transparency reports exist, how promptly privacy inquiries are addressed, and whether changes to policy are flagged proactively. Backblaze is the stronger performer on transparency overall. Without clear and accessible privacy communication, informed consent and trust are impossible. Scores: Backblaze 10/10, Google Drive 7/10.
What Their History Reveals
Looking at how a service has handled privacy incidents, regulatory actions, and disclosed vulnerabilities over time adds essential context. Backblaze carries the better historical record on privacy, having faced fewer incidents and dealt with the ones that did come up more responsibly. How a company has acted before is usually the clearest signal of how it will act on privacy going forward. Scores: Backblaze 10/10, Google Drive 8/10.
Overall Verdict
Our comprehensive analysis gives Backblaze a total score of 54/60 and Google Drive a total score of 38/60. The overall winner for privacy is Backblaze. While both services serve similar functional needs, the winner demonstrates a more privacy-respecting approach across the dimensions that matter most. That said, no service is perfect, and users should always configure privacy settings actively regardless of which option they choose. We recommend supplementing your choice with additional privacy tools, a VPN, DNS-level ad blocker, and privacy-focused browser, to build a comprehensive privacy posture. If your threat model requires the strongest possible privacy, consider whether an even more privacy-focused alternative exists in this category beyond the two compared here.
