Facebook lost 1 Billion Photographs due to Hard drive failure

Facebook lost 1billion photographs
I got hundreds of email on this weekend about their pictures just disappeared from famous social networking site Facebook. When i refered to Facebook blog i got the shock of my life that Facebook lost more than 1 billion photograph, which are 10% – 15% of total photographs hosted on facebook due to hard drive failure.

According to Facebook several drives failed at once during a routine upgrade Friday night.

“You may have noticed in the past day that some photos aren’t appearing or are displaying a ‘question mark’ graphic when you go to view them. We’re trying to fully understand what happened, since simultaneous hardware failures like this are rare” Evan Priestley, an engineer at Facebook Inc.


Facebook still is not quite sure how the outage happened.

Priestley also wrote, “During an otherwise routine software upgrade on Friday night, we ran into some problems with our photo storage and a few of the hard drives where we store photos apparently failed all at once. We are trying to fully understand what happened, since simultaneous hardware failures like this are rare.”

Though facebook guys said that they have recovered one-third photographs, however, i dont think they will able to put things back to normal in a week time.

For some people who use facebook for keeping their business contact this lost is nightmare. Although Facebook is no stranger to uptime issues, with minor but noticeable outages hitting the social network as recently as two months ago. However, this is different and more serious in sense of effecting user hosted data.

So advice for everyone who use facebook. please always keep backup of your data to your hard drive or upload stuff on some other websites.
