How does Backblaze’s server-side encryption work?

Server-side encryption protects your data by encrypting it at rest before it is stored on disk within the Backblaze B2 storage cloud. It can be turned on for use with new and existing buckets, via API or web UI. You can choose SSE-B2 if you wish for Backblaze to manage encryption keys, or SSE-C if you wish to self-manage encryption keys.

What is Backblaze’s privacy policy?

We know privacy is important to you. It’s important to us, too. The Backblaze Privacy Notice describes how we collect and use your personal information, what we do with the information collected, and how you can exercise your privacy rights.

Does Backblaze B2 offer redundancy when storing data?

When you upload data to B2 Cloud Storage, your data is stored on a Backblaze Vault. Each file you upload is stored redundantly across multiple drives, in multiple servers, in multiple locations in our data center. For more details, see our blog post on Backblaze Vaults. If you wish to store data to multiple regions given your redundancy requirements, we recommend you consider the use of Cloud Replication to support doing so automatically.

Does Backblaze support the use of a Personal Encryption Key (PEK)?

Yes, PEK is available for all users. With a PEK, Backblaze cannot access your data, even in the case of a lost or forgotten password, subpoena, or any other event.
