Welcome to Backblaze! Thank you for using our service. We're glad you're here.

These Terms of Service ("Terms") apply to your use of Backblaze's website, products, and services. Please read them carefully and let us know if you have any questions.

All content on Backblaze is protected by intellectual property laws. You'll find a few different types of content on our service.

Your Files.
You can back up, host, store, and share your own files on Backblaze. The materials you upload to Backblaze are yours and yours alone. You give us permission to use that material solely to do what's necessary to provide our services, including storing, displaying, reproducing, and distributing those materials. We don't sell your materials to third parties, and we don't use them for advertising purposes.

You're solely responsible for the files you upload to Backblaze and assume all risks associated with them, including intellectual property or other legal claims. By storing files with Backblaze, you represent that you have the necessary rights to that material, and that doing so doesn't conflict with any licenses you've granted to others.

B2 Cloud Storage in particular allows you to share your files with others. Please be careful about what you choose to share. Backblaze doesn't actively monitor the files you upload. However, we have the right to remove files you store with Backblaze for any reason (such as copyright infringement, we learn the material is patently unlawful, etc.) We assume no liability for any content that you or anyone else stores with Backblaze.

Backblaze is provided "as is" without any warranties, express or implied.

Backblaze disclaims all warranties and conditions of merchantability, fitness for a particular purpose, and non-infringement.
(Some states don't allow these disclaimers, so this provision might not apply to you.)

Limitation of Liability

To the fullest extent allowed by law, Backblaze shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses resulting from (A) your access to, use of, inability to access, or inability to use Backblaze; (B) any third party conduct or content on Backblaze, including any defamatory, offensive, or illegal conduct of third parties; or (C) any unauthorized access, use, or alteration of your content.
(Some states don't allow these limitations, so this provision might not apply to you.)

Arbitration and Opt Out

We'd like to resolve any disputes fairly and quickly. Toward that end, if you have any issue with Backblaze, please contact us and we'll work with you in good faith to try to resolve the matter.

If we can't solve the dispute informally, and if you are a resident of or have your principal place of business in the United States or Canada, you and Backblaze agree to resolve any claim against each other through final and binding arbitration, including claims against Backblaze affiliates, officers, directors, employees and agents, and Backblaze affiliates' officers, directors, employees and agents.

You and Backblaze agree to submit the dispute to a single arbitrator under the Commercial Arbitration Rules of the American Arbitration Association (AAA) including the Optional Rules for Emergency Measures of Protection and the Supplementary Procedures for Consumer-Related Disputes, or, by separate mutual agreement, to another arbitration institution. The AAA's rules and a description of the arbitration process are available at The location of the arbitration and the allocation of fees and costs shall be determined under the AAA rules, except that Backblaze will reimburse you for all AAA administrative fees in disputes that are subject to the Supplementary Procedures for Consumer-Related Disputes, unless the arbitrator determines that a claim or counterclaim was filed for purposes of harassment or is patently frivolous.

The award rendered by the arbitrator shall include costs of arbitration, reasonable attorneys' fees and reasonable costs for expert and other witnesses. However, if your claim for damages does not exceed $75,000, Backblaze will pay for all reasonable filing, administrative, and arbitrator fees, as long as the arbitrator determines that your claim is non-frivolous. If you win an arbitration award that's more generous than any offer we made to settle the dispute, Backblaze will pay you $1,500 on top of the award. Any judgment on the award rendered by the arbitrator may be entered in any court of competent jurisdiction.

The Federal Arbitration Act governs all disputes between you and Backblaze. The arbitrator will decide whether a dispute can be arbitrated.

If you opt out of the arbitration agreement (as provided below), or if the arbitration agreement is found to be unenforceable, or if you neither are a resident nor have a principal place of business in the United States or Canada, you agree to resolve any claim you have with Backblaze exclusively in a state or federal court located in the City and County of San Francisco, California, and to submit to the personal jurisdiction of the courts located in the City and County of San Francisco, California for purpose of litigating all such disputes.

Nothing shall prevent either party from seeking injunctive or other equitable relief from the courts for matters related to data security, intellectual property, or unauthorized access to the services.

To the extent permitted by law, you agree to file any claim you may have against Backblaze within one year after such claim arose. Otherwise, your claim is permanently barred.

Class Action and Trial Waiver

You and Backblaze agree that each may bring disputes against the other only in an individual capacity and not on behalf of any class of people. You and Backblaze agree not to participate in a class action, a class-wide arbitration, claims brought in a representative capacity, or consolidated claims involving another person's account. You and Backblaze agree not to combine a claim subject to arbitration under this agreement with a claim that is not eligible for arbitration under this agreement. You and Backblaze agree to waive the right to a trial by jury for all disputes.

Your Right to Opt Out of Arbitration

You may opt out of the agreement to arbitrate. If you do so, neither you nor Backblaze can require the other to participate in an arbitration proceeding. To opt out, you must notify Backblaze within 90 days of the date that you first agreed to these Terms. To opt out by mail, send your written opt-out notice to this address:

Backblaze, Inc.
c/o Arbitration Opt-Out
500 Ben Franklin Ct
San Mateo, CA 94401

Your written opt-out notice must include (1) your name and residence address; (2) the email address associated with your account; (3) a clear statement that you want to opt out of this arbitration agreement; (4) date sent, and (5) your signature.

Alternatively, you can opt out online by fully sending an email with the above information to:

Governing Law and Jurisdiction

These Terms will be governed by the laws of the State of California, except for its conflict of laws principles.

For claims that aren't subject to arbitration, we each agree to submit to the personal jurisdiction of a state court located in San Francisco County, California or in the United States District Court for the Northern District of California.

Entire Agreement

These Terms, our Privacy Policy, and our Payment and Refunds page constitute the entire agreement between you and Backblaze. If any provision of these Terms is found to be unenforceable, the remaining provisions of these Terms will remain in full force and effect.

No Waiver

No waiver of any provision of these Terms shall be a further or continuing waiver of that term. Backblaze's failure to assert any right or provision under these Terms does not constitute a waiver of that right or provision.


The Terms may be modified from time to time. The date of the most recent revisions will always be at If we make changes that we believe will substantially alter your rights, we will notify you. You'll agree to accept any changes or revisions to the Terms by continuing to use Backblaze.
