2015 - Backblaze offers low-cost Amazon S3 rival

Backblaze, the company known for its consumer and enterprise backup service, is taking a step in a slightly different direction by announcing Backblaze B2, a competitively priced cloud storage service that competes with the likes of Amazon S3 and the cloud storage services that are part of Microsoft Azure and Google’s Cloud Platform. The price of Backblaze’s service is half the price of Amazon Glacier, AWS’s very slow cold storage service, and only costs about a fourth of Amazon’s regular S3 service. Maybe you want to store your data in a number of different locations and services, but if you did that on AWS, you would spend twice as much as you do today. Given Backblaze’s low prices, you could now store an extra copy of your data for about 15 percent of the price you’d pay on Amazon’s cloud storage service. The company expects that users will use Backblaze B2 to store images, videos and data sets, for example. Backblaze B2 will offer a free tier (up to 10GB storage, 1GB/day of outbound traffic and unlimited inbound bandwidth). Developers will be able to access it through an API and command-line interface, but the service will also offer a web interface for less technical users.

2008 - Backblaze: Possibly world's easiest online backup

I just got the preview for Backblaze, yet another online backup service. Or to use the current vernacular, cloud storage.
It's a nifty service in that it does but one thing: back up your PC
(Macs coming). Setup is so easy my cat could do it: you grab the
software, run it, enter in an ID and password, and you're done.
By default, Backblaze begins to backup your PC in idle times, grabbing
everything on your disk except the contents of your system and program
directories, and your temp files. There's no storage or bandwidth
limit, and it will store files up to 4GB in size. Backblaze costs $5 a
month--quite reasonable.

If you want to change the default backup directories or filter out
files by type, you can do that in the control panel. You can also
change the backup schedule so the app isn't constantly waiting for idle
time to send data. The service, as simple as it is, also gets geek cred
for giving users the option to set a private encryption key for their
data; if you use this option, even Backblaze won't be able to recover
files if you lose your password. On the other hand, Backblaze can't
access open files, which means it won't back up your Outlook e-mail
unless you remember to close the app. Mozy handles Outlook better.

If you want a highly configurable backup solution, there are plenty of competitive options (Mozy, for instance, or Carbonite,
which I use). Backblaze is the backup app you recommend to your mom, or
anyone else who should be backing up their computer but is either too
scared of the technicalities or too lazy to do the work necessary to
make sure the app grabs all the files it needs to.
Backblaze will let users access files they've backed up from
its Web site, but it is not designed for that. It's not a sharing or a
syncing platform. And I'm not impressed by the restore services. Since
the app doesn't back up your entire PC, you can't use it to do a
bare-metal rebuild of a machine from backup. You can't even do a
restore of all your data over the Web: You can get up to 1GB of data
downloaded at a time (in Zip files--not exactly user-friendly), or
4.7GB on a DVD (for a fee), or, in a real catastrophe, up to 160GB on a
USB hard drive sent by overnight mail to you (for more of a fee, but
not a usurious one).
