Made by ex-Apple Employees

Some of the Backblaze team members worked at Apple building great products, so we know how to make great software for the Mac. Making high-quality products is in our DNA.

Simple and Easy

Every online backup program says they are easy to use. It's almost become a cliche. But at Backblaze we really wanted that to be true from start to finish. An example is the install experience. By taking a similar approach as Time Machine and backing up all user data, Backblaze doesn't have to ask the user to pick a bunch of filetypes and go looking for folders they want to backup.

Most users don't know where iMovie keeps their projects or their email is kept. Also, we didn't want users to have to remember to go back and edit their backup list every time they create a new folder. Sure some extra stuff is going to get backed up, but the ease of use and peace of mind is worth it. We wanted a user to download and install Backblaze and be backing up data in less than a minute. Mac backup truly has never been easier or better.

Lightweight Performance

We hate using software that slows down our computer, so we wanted to be sensitive to the performance hit on the computer. We did a bunch of amazing magic to optimize the software, including: reading data once, slowly scanning the drive, and waiting a few minutes before backing up at start-up time.

The result is that Backblaze uses less than 1% of your CPU and memory on average. Backblaze doesn't install any drivers and opens any files it backs up as read only so your computer is kept stable. Backblaze also works great running side-by-side with Apple Time Machine for added security.

Native and Integrated

We didn't take a short-cut and create a Java app that can run on many platforms. Instead we wanted to create a product that felt integrated well with the Mac. So we built Backblaze's cloud backup for Mac using Apple's Xcode and put the controls in the System Preferences using a native interface. It doesn't matter if you are running macOS 10.8 or higher, Backblaze's online backup service will work for both.

System Requirements

  • Intel Mac
  • MacOS 10.8 or higher
  • Broadband Connection
  • 5 GB of free space

We thought backup could be so much easier and set out to make it with care.
