There is an option to have a 128 GB flash drive FedEx to you or an external drive up to 4 TB for an additional fee. You can also access your files with the iPhone or Android App.

Your Data is Safe

Backblaze takes security seriously. All data is stored in our secure datacenters with 24-hour staff, biometric security and redundant power. Learn how Backblaze uses encryption to protect your data.
New: Backblaze has enabled two-factor authentication. Now a 6-digit code can be sent to your phone during sign-in for an extra layer of security.


All your files are encrypted before being transmitted over SSL and stored encrypted.

Personal Key

You can use a personal encryption key for additional security. If you lose your password, Backblaze will be unable to send it to you.

No Java Software

Java is responsible for 91%* of security attacks. Backblaze's code is native to Mac and PC and doesn't use Java.

Continuous Backup

Files change and Backblaze backs them up. By default Backblaze’s cloud backup solution simply backs up all the time so you don't have to remember. But if you wish, you can schedule Backblaze to backup at a convenient time or only when you click "Backup Now".

Backup Speed

The average customer takes two weeks to complete an initial backup. Backup speed depends on how much data needs to be backed up and how fast your internet connection is. Backblaze will automatically adjust to your network or you can adjust the settings to your own liking.

Lost Computer

If your computer is ever lost or stolen you should immediately restore your data to another computer. Backblaze has the ability to locate your lost computer to help inform the authorities of where to recover it.
