Viewing cloud storage data security from Sheng disk corruption

With the rapid development of cloud computing, people's understanding of cloud storage is also gradually widespread, whether some enterprises or some individuals, have been stored in the cloud of data, but the cloud data storage is safe and thought-provoking.

In recent days, there have been some bad news about cloud storage security. On August 6, Sheng issued a statement on its official microblog, saying that the loss of individual user data was caused by the damage to a local disk in a physical machine in the Wuxi room. However, as soon as the announcement was made, it was immediately challenged by larger users. Netizens have accused, "Sheng why the host does not back up, but also need the user to back up." "There are even those who think this is a wake-up call for domestic cloud makers." Coincidentally, August 7, Apple icloud cloud storage was black, unexpectedly easy to let hackers succeed, "one second" intrusion system and delete all data. What is even more startling is the findings of the "Hacker attack icloud system" incident: The hacker correctly answered all security questions through Apple's technical support and social networking surveys, and was able to modify icloud passwords, delete information, and so on. This shows that Apple should be responsible for this incident, and Forbes also advised Apple to deal with the matter as soon as possible. Finally, Apple reacted at the first time: Immediately told the technician to stop anyone from resetting the Apple ID password on their phone.

The recent case of cloud storage data loss from above tells us that cloud storage is risky and clouds need to be cautious. Cloud storage is not omnipotent, do a good job of data backup is the key. Of course, whether domestic or foreign cloud storage, will not be so calm, often walk in the river, where there is not wet shoes, but the consequences are quite serious, the following for everyone to take stock at home and abroad in the cloud storage major accidents.

Microsoft's sidekick accident

Sidekick The accident was so serious that, in the winter of 2009, Microsoft's sidekick service was interrupted for one weeks, users couldn't access their mailboxes, calendars and other personal data, and more seriously, the error lasted one weeks. Microsoft later admitted that the data could not be recovered, because technicians forgot to backup, and as time went on, the low-level mistakes of forgetting to backup should not happen again, but the lesson was serious, whether you were using cloud storage or not, you needed to back up your data. As Alertsite, vice president of product monitoring, Kengodskind, says, the agency that uses the cloud cannot simply assume that it is in the cloud and that the full responsibility for the business continuity plan has been given to the provider.

Google's Gmail glitch

Gmail this mistake and everyone is closely related, there are 150,000 of users in their Gmail account, see a blank page, users suddenly dizzy, Google to repair the failure of the time spent four days, Google's vice president of the project Bentreynor then said in the blog, If you have multiple copies of your data, how could such a thing happen? In rare cases, software flaws can affect several data. That's what's going on here.

Thankfully, Google has switched to physical tape backups to restore data. Ultimately, Google's multi-tier data protection did work, but thousands of of users were unable to access their e-mails in the next few days. When you look at the broad average, the success rate of the cloud is much higher than your personal success rate, says Kengodskind of Alertsite. This is only when you get to the web scale, the impact of the failure is magnified in a larger way.

Cloud provider Terremark Serious accident

Recently, the 1 billion dollar deal between Terremark and Verizon may have been a major news story. However, in early 2010, the main news reported was the Terremark accident.

On March 17, 2010 the Terremark Company's Vcloudexpress service plunged in the middle of the day, breaking the network for about 7 hours in Miami's data center. During this time, users cannot access data stored in the data center.

No more redundancy. However, this brings the value of redundancy, allowing your important data to be provided to multiple servers in different data centers, or preferably to multiple servers in different regions. As a fail-safe, you can also take additional steps to spread data to different providers.

Amazon Web Service outage

Tedious network maintenance work is annoying, but in the operating system is not very mature premise, the use of startup will maintain a very high risk, typical settings and general settings of specific parameters, are not known to users, in the event of a failure, users will immediately become bewildered, Because he had no idea what was hidden behind the platform. Amazon's worst failure, in the Amazon U.S. North Virginia Data Center, a serious failure occurred, this error is a wrong route of the mobile communication, a series of Amazon EBS Traffic sent to a new mirror, this anomaly caused the U.S. Amazon in the eastern region of the massive disruption of services, What is more frightening is that this error lasted four days without repair. Many enterprises were quickly caught in the lurch, causing serious losses.

Edit summary: See here, I think a lot of people will have the same idea with me, that is, where is the data to be safe? Simply put, cloud storage is guaranteed for data security, but some people confuse a definition, like safe and security in English, but with different meanings, cloud storage ensures that your data is not lost and provides you with data synchronization and backup. However, it is not entirely possible to keep your data private and confidential. To fully resolve the latter, cloud storage will be your most reassuring choice. To the reader's advice, whether the storage is in the cloud, data backup is the key! There were many opportunities for backup before me, I did not cherish, until one day years of painstaking efforts, I just regret, if God gave me another chance, I would like to say: "I must do a good backup", if you want to add a number of these backups, I hope it is "N" times. I hope you learn from the data loss such a painful lesson, we must do a timely backup, or regret it too late.
