LinkedIn open sources its database change capture system

Mark Gibbs | Feb. 28, 2013
OK, lots of interesting stuff for you this week. First up, LinkedIn has open sourced a system called Databus, a real-time database change capture system that provides a "timeline-consistent stream of change capture events ... grouped in transactions, in source commit order."

The backup service offered by Backblaze is really impressive. A small download for Windows or OS X, a fast and painless installation, and you're backing up. Backblaze doesn't throttle your backups or recoveries in any way; they'll transfer data either way just as fast as your connection allows with encryption, de-duplication and compression.

Need to restore? You can download files via Backblaze's Web interface or have them ship you a 64GB USB drive via Fedex for $99, or a 3TB hard drive for $189 (you get to keep the drive). Versioning is supported along the same lines as Apple's Time Machine (incremental backups with hourly changes for the past 24 hours, daily changes for the past month, weekly changes for the quarter, and quarterly changes for the year with restoration of all duplicated files to their correct locations).

For it's elegance and cost-effectiveness, the Backblaze online backup service is remarkable and gets a Gearhead rating of 5 out of 5.

So, did the Pod hardware design work out for Backblaze? You bet! The company was bootstrapped by the founders and last year, after five years in business and with a storage capacity of an impressive 40 petabytes, Backblaze decided it finally needed to raise a VC round for $5 million to accelerate their growth ... and that wasn't nearly as much as VCs were reportedly willing to fund them.

Could the Pod 3.0 design work for you? Sure. It's not designed for your superfast primary storage, but as a secondary storage solution it's way cool and very cost-effective. You can buy just the Pod 2.0 cases from 45 Drives for $872 each or completely assembled systems with a somewhat upgraded specification for $5,395 each (Pod 3.0 versions are due in the near future).

For any company looking at optimizing its storage costs the Backblaze Pod 3.0 whether home-built or purchased from the likes of 45 Drives is a very compelling way to go. If you're using any of these systems or considering doing so, let me know ...
