4. Hard Lessons Learned August 2011 April 2011 April 2011 : Amazon's huge EC2 cloud services crash permanently destroyed some data…. Amazon didn't say explicitly whether it was human error that touched off the event ….. August 2011: Lightning Strikes Out Amazon’s Cloud „ … . Separately, and independent from the power issue in the affected availability zone, we’ve discovered an error in the EBS software that cleans up unused snapshots. During a recent run of this EBS software in the EU-West Region, one or more blocks in a number of EBS snapshots were incorrectly deleted. The root cause was a software error that caused the snapshot references to a subset of blocks to be missed during the reference counting process ….. „ „… .. Not only are 18 days of backups for some volumes gone, the majority of the remaining snapshots have been corrupted by Amazon’s backup system . ….“

5. Hard Lessons Learned Feb 2011: Google restore gmail from tape … . I know what some of you are thinking: how could this happen if we have multiple copies of your data, in multiple data centers? Well, in some rare instances software bugs can affect several copies of the data. That’s what happened here. Some copies of mail were deleted, and we’ve been hard at work over the last 30 hours getting it back for the people affected by this issue. To protect your information from these unusual bugs, we also back it up to tape . Since the tapes are offline, they’re protected from such software bugs . So what caused this problem? We released a storage software update that introduced the unexpected bug, which caused 0.02% of Gmail users to temporarily lose access to their email. When we discovered the problem, we immediately stopped the deployment of the new software and reverted to the old version. Tape is, last line of defense !
