Do you have lots of "old" data? Does your company archive huge volume of data? If yes, one needs to know this: ageing data is highly susceptible to a mischievous type of tampering popularly know as "Bitrot" or "Data Rot". Data living on storage media are prone to such "insidious" errors due to drive firmware bugs, mechanical wear & tear of rotational media and the likes. Worst, an application relying on such data is practically clueless about it's tampering as there is absolutely no indication from the disk to the storage software layer about such errors. Even data protection mechanisms such as RAID give it a blind eye unless expensive and time consuming approaches are employed.

In this session Gaurav Garg explains how GlusterFS solves this problem by providing an easy and efficient mechanism to detect (and correct) bitrot. This is followed by a quick demo of the implementation.
