What is Backblaze B2 Cloud Storage?

I am allowing you to store unlimited data in the cloud. Backblaze B2 Cloud Storage works similarly to Amazon S3, Microsoft Azure, or Google Cloud. You can use it from any computer, operating system or cloud storage. But it does it for 1/4th the cost. 

Files are available for download anytime, either through the API or a browser-compatible URL. To use B2 Cloud Storage, you need to have a Backblaze account.

There is no confusion on Backblaze B2 pricing; it’s very
simple, there’s only one storage type to choose from, and the rates are fixed.
Backblaze charges for both egress and API calls, Unlike Amazon S3, Microsoft
Azure, Google B2 is only $0.005/GB per month for data storage, $0.01/GB to
download data and the first 10GB of B2 Cloud Storage and 1GB of downloads each
the day is free. 

Storage after that costs half a penny per gigabyte per month but
Backblaze doesn’t provide any discounts for those who store terabytes of data,
but that’s not a problem.

The B2 dashboard has valuable information to help manage your
account, including the size of buckets and how many files are in them.

The storage for your account is grouped into buckets. Each
bucket is a container that holds files. You can create up to 100 buckets per
account, and they can store as much data as you need and any file.

There’s a maximum file size, but at 10TB, it shouldn’t cause any problems. When you create a bucket, you’ll be asked to give it a unique name and set it to public or private.

Where anyone can access public buckets, an authentication token is required to access private buckets. Each bucket has a set of lifecycle rules that instruct B2 to hide or delete old versions of
files. 

Backblaze lets you change public buckets into private buckets or
vice-versa. Backblaze supports drag-and-drop, which makes them unique compared
to Google Cloud, Microsoft Azure or Amazon S3.

There’s a “reports” tab with higher-level account
information, such as total gigabytes stored and downloaded.

You can determine the size of each part you upload and copy.
For example, if you’re uploading a 100GB file, you could make each part 1GB,
and perform 100 uploads, 1GB at a time. The maximum part size is 5GB, and the
minimum part size is 5 MB. Backblaze recommends a part size of 100MB, which
strikes a good balance between upload throughput and the ability to upload
parts in parallel. Uploading the same file name more than once results in
multiple versions of the same file. This can be useful for tracking the history
of a document. See File Versions for more details.

Backblaze has four data centres, three of which 3 of them in the united
states, namely (the US West) and Amsterdam (EU Central). Before
choosing the right region, you can test your connection speed and check latency
when connecting to the B2 network using Backblaze’s speed test tool.

Backblaze replicates your data in multiple drivers and servers despite having lower data centres. Backblaze B2 encryption includes in-transit but not at-rest protection. This must be considered as one of their drawbacks which move most of their client to choose wasabi or any other provider. If you still need to use Backblaze, then you need to use any third-party tools to encrypt your data before uploading it to the cloud also supports two-factor authentication.
