Humor from Data Security

When you see a terrible episode of a horror film, or when you see something that shocked your mood, I believe that everyone is not a weak one, saying "terrible", "scared" or something. The first sentence of the subconscious is not "grass mud horse" or "I wipe ". 650) this. width = 650; "src =" http://www.bkjia.com/uploads/allimg/131227/0A15R248-0.png "Style =" border: 0px; margin: 0px auto; padding: 0px; display: block; "/> ===================================================, this is also thrilling. It happened on February 12,). In fact, I did not expect this situation or the results. I often read the blog of Jiu Shu, And I will probably know that there are many xenservers using Citrix, and XenServer is a basic platform for virtualization, it shares the majority of the virtualization market with VMWare and HyperV. Of course, VMWare is the best. We will not discuss the details of the market share here. In all fairness, XenServer is still very good. From the perspective of its usage over the past few years, it rarely experienced problems. Because the underlying system is a Linux system, it is better to use the Guest system as a Linux system. I have a test machine in my hand and the version is updated at any time. Now it's XenServer6.1, but the hardware of this machine is a little miserable. It's a dual-U Tower server in. On this test machine, I usually some testing environment machine, as well as to facilitate WDS capture image, put a Win7-32/64, XP, 2003 a total of 4 operating systems, and my personal websites. Because XenServer is stable to use and is a test environment, you have never considered what to do if the machine breaks down. The overall "feeling" is that the above data is lost and it is okay, the problem is not big. ============================================ It was found that the WDS image capture speed was very slow near the end of work on Friday., after checking that the server has not been restarted for several months, I suspect that the memory is leaked, So I restarted it remotely. But this is the beginning of the tragedy. We can leave office at half past five. After the reboot, the disk of XenServer cannot be mounted. XenCenter prompts that the local storage fails to be mounted and needs to be repaired. At that time, my heart was quite cool. These virtual machines that don't matter, just let me crash. Although these things are not important, if the hard disk crashes, it will be difficult to recover, especially the WDS image, which has no technical content, it is to pre-install some software required by the Company's office. to re-install it, how can we build it in two days. In addition, there are also virtual machines with personal websites. This will make people ignited. Although this is a poor Website access volume, you have to record the information for many days, and you still don't know if you can find the backup. ============================================ In fact, the final hard disk was mounted by me, how to implement this is a technical issue. It has nothing to do with today's article. Of course, from half past five to half past eight on Friday, the soul in this period is hard to understand ), I would like to share with you some of my views on this matter and hope to make some use of it. I also hope that you will not be bothered by such data loss.

1. Is the test machine really just a test?

There is no doubt that, in the initial vision and design, this tester is indeed the content of the test run, and there is no doubt that the data above it is not important, no backup or disaster recovery considerations are required. However, in actual use, some items that pass the test and verification will be migrated to the work environment. At this time, the virtual machines on the test machine are not used for testing, it is valuable. The problem is not whether it is a testing machine, but that the testing environment sometimes produces valuable data. 2. Is Data Validation dispensable? Data on the test machine is not important at the beginning, because backups can be found on other online machines. However, if we need to verify a feature that exists in a complex environment, such as the deployment of complete Lync best practices and the deployment of complete Exchange best practices, these are all links that require at least five virtual machines to participate. It doesn't matter if data is lost in a test environment like this? Obviously not. It takes a lot of time to build such a platform even in a test environment without reference data. At this time, if we say that we have just set up a good environment, but we cannot access it because of the failure of hard disk storage, I believe that there will be 10 thousand gradients in our hearts. 3. can I find it? Just because of the time relationship, we can say that it is impossible to find the data, but if the storage really fails, and this is still a physical machine advertised as a "Test Machine, in addition to self-reliance, it may be difficult to find a reason to spend a lot of money on data recovery. It's a pleasure to be able to find it back. If you can't find it, cry and cry to your mother. From the moment when data generates value, we have decided that we can't cut off the data. 4. Why are your mentality changing? From the very beginning, we did not pay much attention to the test environment. However, when there are more and more things to be tested and we are "communicating" with the testing machine, we will find that we have a different sentiment with the testing machine. When emotions become a habit, they are suddenly lost, which is truly unacceptable. 5. Don't regret it when you lose it. To solve this problem, the solution is very simple, that is, to deploy the corresponding backup plan on the testing machine, and to prepare a disaster recovery solution as a formal environment. However, at the beginning, we tend to focus less on this issue, and the result is one hundred before the end. In the IT industry, preparing for a rainy day is a positive comments. ======================================== When we find that data is valuable, it is often the time when a disaster has occurred.
