Backblaze takes security of the data that is being backed up very seriously.
For our Online Backup service, we encrypt all files on your computer before transmitting them to our servers using the AES 128-bit encryption algorithm. Secondly, we transmit this encrypted data using an encrypted connection (HTTPS) to our data center. The data is then stored on one of our many storage pods in this encrypted format. You can learn more about our encryption here. For additional security, you can specify your own private encryption key. If a private encryption key is specified, the data is encrypted to that key and only the key will unlock it.
For our B2 Cloud Storage service, we offer highly durable and secure storage and encourage users to take advantage of encryption features offered by many of our B2 Integration Partners to encrypt their files before uploading them. You can learn more about the Security and Redundancy of B2 Cloud Storage here.
We do also offer the option to apply Server-Side Encryption to backups. You can find out more about our Server-Side Encryption and how it works in our Server Side Encryption FAQ and Enabling Server Side Encryption guide.
While Backblaze is not a HIPAA covered entity, many of our customers are, and we are happy to provide Business Associate Agreements (BAA) to our customers. To learn more and to request a BAA, please visit this page.
