Backblaze Review

Backblaze is an online backup service for Windows and Mac.  It backs up your most important files to their servers, which can later be restored in the event of a disaster.

Backblaze is a pioneer of the “unlimited backup” movement, and in my opinion one of the best online backup services out there.

Backing Up

After installing, Backblaze automatically scans your hard drive for files to back up.  It will also backup all connected USB drives at the time of the install (you can add more later).

Backups are automatic and continuous; your files are backed up constantly throughout the day.

Backblaze also has an option to “Transfer Backup State.”  This lets you transfer your account to a new computer, without having to re-upload all your files again.

Restoring Files

Option 1: Download Your Files

When your computer crashes or you lose data, getting your files back is the first thing on your mind.  Fortunately, Backblaze makes this easy.

You can download your files through the web interface.  Your files will be compressed to a .zip before downloading, and for 100GB worth of data this will take about 4 days (according to my speed tests).

Option 2: Get Your Files Mailed to You

If you have a large amount of data, it might be faster to have them mailed to you on a USB flash drive or external hard drive.

The price for the USB flash drive is $99, and it holds a maximum of 53GB.  The external hard drive costs $189, and it holds a maximum of 3TB.

Backblaze says it can take 2-3 days to mail the drive.  With overnight shipping, that’s up to 4 days before you can get your data back.  At this point it might be faster to download them, depending on your internet connection speed – something to keep in mind.

Preferences and Settings

Although Backblaze is very good at picking the best backup plan, there are a ton of settings to customize if you want to.

Excluding Files

You can exclude folders, file types, and files over a certain size.  There are a lot of exclusions already set, mostly system files and other files you wouldn’t normally back up.

The default max file size is 4GB.  This can be changed anywhere from 5MB to 25GB, or turned off with “no limit” (like I prefer).

How Long are Deleted Files Kept?

Deleted files are kept for 30 days.

In other words: if you delete a file on your computer, you have 30 days to recover it before it’s deleted from the Backblaze servers.

What About Multiple Versions of Files?

If a file changes, Backblaze will keep up to 34 versions.

Backblaze will backup:

  • One version every hour, for the last 24 hours
  • One version every day, for the last 7 days
  • One version every week, for the last 4 weeks

This way, you can restore files even if they’ve been overwritten by newer files (such as a text document you’re working on).


Backblaze is very fast when backing up and restoring files.

The backup speed maxed out my upload bandwidth at 7.8 megabits per second (Mbps), which is about 80 gigabytes per day. Restore speeds averaged 17.7 Mbps.  This means it would take about one day to restore a 200GB hard drive over the internet.

Mobile Apps

Backblaze has apps for Android and the iPhone (although not the iPad).  With the apps, you can access your backed up files on the go.  I should also note that the mobile app is limited to downloading files 30MB in size.


Backblaze transfers your files using SSL, which ensures nobody on the network can see what you’re backing up.  This is important with public WiFi such as coffee shops or hotel rooms.

All your files are stored using 128 bit AES encryption.

Your files can only be viewed by entering your email and password.  If you want even more security, you can specify a private encryption key (which not even Backblaze has access to).  However there is no “password reset” for this feature; if you forget your key your data becomes unrecoverable.


To contact support, you can submit a support request through their online help desk.  I submitted a request and was responded to quickly, within 1 business day.

For a more immediate response, Backblaze now offers live chat support, available from 9 a.m. – 5 p.m. PST. Backblaze does not offer phone support.  They do have an online knowledgebase, FAQ, and How-to guides.


Backblaze is fast, easy to use, and keeps your files protected 24/7.  However, be sure to turn off the 4GB file size limit if you’re backing up large files, such as high definition videos.  Other than that, it’s hard to find any faults with Backblaze.

The company’s commitment to security, ease of use, and providing a great service has built them a loyal following of fans (including me!).

If you’re looking for an unlimited online backup service, Backblaze is a great choice.

    Thanks for the review. I tried Crashplan first, and then Backblaze. I found Backblaze really good, and already bought the 1 year plan. The first backup took a long time (about 2 weeks) but now it’s always up-to-date. I am outside US, and the upload speed was about 1.00 MBits/sec. When I have to retreive a backup file I’ll write the rest of my review :-)
