We are thrilled to share the results of a project that has engaged the Backblaze engineering team for the last year: Backblaze Vaults, a major step forward in our cloud storage service’s technology stack. Currently Backblaze stores over 150 petabytes of data and has recovered over 10 billion files for customers of our cloud backup….
Backblaze now has 150 Petabytes of customer data safely stored by our cloud backup service and waiting to be restored by our customers when requested. This customer data is stored encrypted on 980 Backblaze Storage Pods which contain 44,100 data hard drives of sizes ranging from 2 to 6 Terabytes. Each week, new Storage Pods….
It has been nearly a year since we published an update to our Storage Pod design. Over the last few months we have been deploying Storage Pod 4.5, which is known internally as Storage Pod Classic. The reason for the “classic” nickname comes from the fact that Storage Pod 4.5 is derived from our Storage….
Stats Geeks: Now it’s Your Turn. Backblaze Online Backup has released the raw data collected from the more than 41,000 disk drives in our data center. To the best of our knowledge this is the largest data set on disk drive performance ever to be made available publicly. Over the past 16 months, I have….
It was one year ago that I first blogged about the failure rates of specific models of hard drives, so now is a good time for an update. At Backblaze, as of December 31, 2014, we had 41,213 disk drives spinning in our data center, storing all of the data for our unlimited backup service…..
Backblaze is transitioning from using 4 TB hard drives to 6 TB hard drives in the Storage Pods we will be deploying over the coming months. With over 10,000 hard drives needing to be purchased over the next several months, the choice of which 6TB hard drive to use is critical. Let’s take a look….
I’ve shared a lot of Backblaze data about hard drive failure statistics. While our system handles a drive failing, we prefer to predict drive failures, and use the hard drives’ built-in SMART metrics to help. The dirty industry secret? SMART stats are inconsistent from hard drive to hard drive. With nearly 40,000 hard drives and….
At Backblaze we now have 34,881 drives and store over 100 petabytes of data. We continually track how our disk drives are doing, which ones are reliable, and which ones need to be replaced. I did a blog post back in January, called “What Hard Drive Should I Buy?” It covered the reliability of each….
