Backblaze is a data storage provider. It offers two products:
- B2 Cloud Storage - An object storage service similar to Amazon's S3.
- Computer Backup - An online backup tool that allows Windows and macOS users to back up their data to offsite data centers. The service is designed for end-users, providing unlimited storage space and supporting unlimited file sizes.

Overview
Founded in 2007, Backblaze has raised a total of $5.3M in capital and is profitable.
Backblaze's first product is its Computer Backup offering. It allows the user to back up data continuously, manually, when the computer is idle, or on an hourly schedule. The service makes use of AES encryption for security, and uses data compression and bandwidth optimization to reduce upload and download times. Files that need to be restored can be delivered in the form of a digital download, on an external USB hard drive up to 4 TB or a USB flash drive up to 128 GB.
In September 2015, Backblaze launched a new product, B2 Cloud Storage. Being an Infrastructure as a service (IaaS), it is targeted at software integration (though a web frontend and APIs are also available). It directly competes with similar services Amazon S3, Microsoft Azure and Google Cloud. In April 2018, Backblaze announced cloud computing partnerships that directly connect Backblaze's data centers with its partners, offering high performance cloud computing for data stored in B2 Cloud Storage with no transfer fees.

Technology
Data replication
Data uploaded onto Backblaze's data center is sharded into 17 data shards plus three parity shards for each file. Parity shard bits are computed by the Reed-Solomon error correction algorithm. The shards are stored in 20 storage pods, each in a separate cabinet to increase resilience to a power loss to an entire cabinet. Backblaze states that its Vault architecture is designed with 99.999999999% (eleven 9s) annual durability.
Encryption
Backblaze utilizes a combination of AES and SSL encryption to protect user data. All data is stored on Backblaze Storage Pods encrypted with the user's private key, which is secured with the user's password and username. Users desiring additional security and privacy wishing to take a Trust No One approach may also use the passphrase system which encrypts the private key with a passphrase not stored on Backblaze servers. However, because decryption of private keys is done server side, this level of security is unlikely to protect against a government subpoena or serious data breach.
Storage Pod open design
In 2009 and 2011, Backblaze released CAD drawings of the computer case used by the storage servers in its datacenters. With commercial off-the-shelf components such as x64 processors, disks, and motherboards, high-density storage servers can be built at a lower cost than commercial ones.
In February 2013, version 3.0 of the pod was introduced with increased storage capacity and other upgrades.
In March 2014, version 4.0 of the pod was introduced which is faster, simpler and less expensive, and then a "tweaked" version 4.5 in March 2015.
In November 2015, version 5.0 of the storage pod was released, in which the motherboard, CPU, and SATA cards were upgraded, and the memory was increased to 32GB.
In April 2016, version 6.0 of the storage pod was released.
