Backblaze Launching Refer-A-Friend


Help Your Friends and Yourself

You back up your computer. You go to bed every night, wrap yourself up in a blanket burrito and think about how peaceful your life is now that you have an online backup; and hard drive crashes no longer loom in the back of your mind. Sometimes you think about your friends, wondering why they’ve never backed up their computers and known the true comfort of having digital peace of mind. Now you can help your friends get backed up, and it’s easier than ever.

Announcing the new Backblaze Refer-a-Friend program

We’re thrilled to announce our brand new Refer-A-Friend program. Starting now you can invite your friends to try Backblaze for one month, free of charge. For every friend that signs up with us, you’ll get one month’s worth of Backblaze applied to your Backblaze account. What could be better than helping your friends get peace of mind, knowing their data is safe, and getting a little something in return too? Possibly doing all of that while eating cake, but that’s about it!

How the Refer-a-Friend Program Works

How will it work? Once you log in to your Backblaze account, you’ll see a “Get Free Months” tab on the left hand side. After going there you’ll see your personal invite link, which you can then tweet, share, or email to your friends. We’ll show you the status of everyone who you’ve invited, and once they purchase, you’ll get a free month’s worth of credit applied to your account, one for each new account that signs up with Backblaze using your invite link.

Get Backblaze Free Forever

Backblaze is all about unlimited, so there’s no limit to how many months you can get for free. That’s right! Get enough of your friends to sign up and your Backblaze can be totally free. So get to it! Invite your friends to Backblaze, get some free months, and help spread some good on the planet!

Release 2.5.1


Release Date: 4/28/2014
Version: 2.5.1
Windows version:
Mac version:

Normally “dot” releases such as 2.5.1 are about making little improvements that go unnoticed by nearly everyone. For example, in 2.5.1 we sped up the file scanning process on the Mac platform by utilizing BSD layer OSX system calls. We also added .pvm files (Parallels) to the default excluded file types list and made a number of other “invisible” tweaks for both Windows and Mac.

In 2.5.1 we did sneak in one feature everyone can see, “The Skipped Files Report”. It works like this. Backblaze automatically creates a list of new and changed files it needs to back up. We then proceed to back up those files. If we encounter a file on the list that we can not back up, Backblaze writes a message line in the Skipped Files Report. In previous versions of Backblaze, we logged this information, but it was hard to find and decipher. Beginning with 2.5.1 you’ll be able to view the Skipped Files Report anytime by opening your Backblaze Preferences, selecting Settings and choosing the Reports (Mac) or Issues (PC) tab as noted below.

Most of the time, the message is self-explanatory as to why a given file was not backed up. A few of the more common messages are listed below. Please contact Backblaze support if you have questions.

  • Permanent Bad Permissions – The permissions on the file will not allow us to read the file for backup.
  • Temporary File Busy – The file is open by another process.
  • Temporary Drive Unplugged – The file we wanted to back up was on an external drive which does not appear to be connected anymore.

In general, Backblaze backs up without incident and you’ll find few if any entries on the Skipped Files Report, but feel free to check from time-to-time.

Backblaze Mobile Update 1.8

blog-ios7Backblaze Mobile 1.8 is here! We’ve added search, making it easier to find and retrieve files on the go!

What’s New:

  • Search — search for any backed up file by name

Search will help you find and view your files and folders while you’re away from your computer. You can search for specific files, through folders, or amongst your various computers.  Adding search makes it much easier to access all of your backed up data quickly and easily.

Next we’re going to go heads-down on an iPad app to add a bit more usability for larger interfaces (though you can use the current app on an iPad) and then we’re off to android!

Backblaze 2.5 – The Tranquility Release


You shouldn’t have to worry about data backup. It should just work. No data limits, no throttling, no worries. That’s Backblaze. Here’s a look at what’s new in Backblaze Online Backup Release 2.5.

Account Page

From any web browser you can log in to your Backblaze account to see how things are going. Most of the time when someone logs in, it’s to do a restore, but on the “Account” page you can; adjust your account settings, check out your billing information, change your password and more. For 2.5 we reorganized the Account page so you can understand your account at-a-glance. For example, all your billing related information is in the same place and it is easy change plans, change credit cards, etc.

R2.5 Account Page

Overview Page

The “Overview” page is where you start when you log into your Backblaze account. We completely redesigned the page to place more relevant information at your fingertips. For example you’ll see:

  • All the computers being managed by your account
  • All the drives (internal and external) being backed up
  • The last time each drive was backed up
  • How much data is selected for back up
  • Drives not being backed up and what you can do to fix it

Email Notifications

One of the things we realized is that many customers use our system for years and never log in to their account. But sometimes something goes wrong; an external drive becomes disconnected or fails, or a customer changes computers and turns off the old one. Things happen. So when we see something amiss we’ll send a notification email to your Backblaze account email.

    We Miss Your Computer — If we can’t communicate with a licensed computer for 14 days, we’ll start sending you emails like the one below.

    A Drive is Missing — We back up the internal and external drives that you’ve selected. If we can’t communicate with one of those drives for 14 days we’ll start sending you emails like the one below.

Backup Summary

Some people are content to “let the backup happen,” while others watch the Backblaze Preferences panel as the number of files to back up counts down to zero. OK, maybe they don’t watch that often, but they do want to know how things are going. Fair enough. With Release 2.5 we will send each Backblaze account owner a Backup Summary email like the one below. You can choose how often you wish to receive this email: monthly, weekly, or not-at-all. This is set on the Account page. The email provides a snapshot of the status of the computers in your Backblaze account.

Unlimited Means Unlimited

Backblaze customers could previously backup a file that was unlimited in size, but the default was set to 4 GB in the Backblaze Preferences for a given file. Beginning with Release 2.5 the default will be Unlimited. We’re not sure why anyone would want anything else, but we are leaving the ability to limit the file size just in case.

Under the Hood

Of course our engineers tinkered with plenty of things a typical Backblaze customer doesn’t notice. For example, in Release 2.5 our Client Engineering team doubled the speed of the file scanner that compiles the list files to back up. This is most evident during the installation process when we do our initial file scan of your hard drive. We also improved how we back up .emlx and .ics files on the Mac and changed over to use the newest Xcode 5 build environment from Apple.

With Release 2.5 we’ve made it easier to stay up to date with your Backblaze account. We hope this brings a little more tranquility in to your life. We will be auto-updating everyone in the next few weeks, but if you can’t wait you can upgrade now, it’s pretty cool.

Backblaze Release 2.3.0:Performance Tuned for the Modern PC/Mac

New release

Release Date: 7/11/13
Version: 2.3

Auto-Update: No

A core tenet of the Backblaze philosophy is that backups have to work seamlessly in the background. As such, we’ve always focused on performance: providing unlimited bandwidth, automatic bandwidth management, and writing the applications natively on Windows and Mac in high-performance “C” code.

In this latest release, we have gone further in optimizing the performance of the online backup service.

Mac and Windows Releases

* SSD detection and optimization.
While only 6% of computers today have solid-state drives (SSD), that number is forecast to increase to 31% by 2017. Furthermore, a significantly higher percentage of laptops (which are prevalent among our customers) have SSDs, and 100% of new Apple MacBook Airs and retina MacBook Pros use them instead of hard disk drives.

SSDs are up to 10 times faster than regular hard drives. A traditional 5400 RPM laptop hard drive reads data at about 50 MB/s, whereas Apple claims their new MacBook SSD (or “Flash” storage) reads data at up to 500 MB/s.

This new release detects whether your computer has SSD or flash storage versus a traditional hard drive and optimizes Backblaze to take advantage of that additional performance to enable your system to back up even faster.

* Retuned RAM usage for modern systems and data distribution.
Over the years, computers have shipped with more RAM and users have stored more files. This release retunes Backblaze to produce the file list for backup 2 times faster for users with large number of files. (Users will small numbers of files will have unchanged performance.)

* Increased file list scalability 8 times.
Backblaze was designed to easily backup hundreds of thousands of files per computer. For the few users with millions of files on a single computer, their experience was suboptimal. This new releases increases the scalability 8 times on 64 bit architectures to improve the experience.

* Instrumented performance analytics.
The Backblaze service will measure various performance metrics in order to help continue tuning the service for higher performance.

* Added additional temporary files to exclusion list.
Added temporary files from Windows 8, Apple Time Machine, and more to the exclusion list to optimize backup speed.

Additionally, on Windows

* Released application in 64 bit.
Backblaze now runs as a 64-bit application on Windows systems that run as 64 bit architectures: Windows Vista 64-bit, Windows 7 64-bit, and Windows 8 64-bit. Backblaze will continue to run as 32-bit on 32-bit Windows (such as Windows XP) and on Mac OS X 10.5 and 10.6. Backblaze on Mac OS X previously supported 64-bit.
