Bloody facts prove the importance of "data backup"

Recently, it was unfortunate that one failed task was followed by another. Then, I reflected on myself. I still had some gains by reflecting on myself. Now I have listed the problems and I will encourage you later:

0. A few days ago, I forgot my master disk and borrowed a copy from my buddy's master disk. I inserted a pop-up window to my computer. I felt something wrong, but it wasn't quite a thing, after the copy operation is complete, go back. I was shocked to go back to the lab and open the computer the next morning. It was just when I did not take the case that the current situation was caused: I started a lot of trojans on the computer. First, I went crazy to kill and clean up the files, after a while, I thought it should be okay now. When preparing to open the development tools and put them into battle, large software such as SQL Server and myeclipse are all on strike. God, these software are all heavyweight, and repair is impossible. They can only be reinstalled. It may take a while to uninstall SQL Server. Sometimes it cannot be used after it is reinstalled because it is not clean. Then, I found a professional uninstall software on the Internet (your uninstall is really good ), one by one uninstallation and another reinstallation. Due to poor computer configuration in the lab, it has been more than two o'clock P.M. minutes since all the operations were completed. How much time has it delayed. My database files were also wiped out. How big was it in my life... In this case, we come to the conclusion that USB flash drives and other mobile devices should never be used in disorder. First, they should not see what they should not see (you know ...), The second is to prevent yourself from being recruited.

1. A lab project will be delivered a few days ago. The user manual is in the sprint phase. I am responsible for writing the functions of the two modules. During this period, I will draw a flowchart and use Visio, after a lot of effort, I finally drew the first image and directly pasted it into the word. When I wrote the second module, I found that the first flowchart could be used here. I only needed to change it a little. But now I found that I forgot to back up the data ...... I had to start over again, which greatly affected my work efficiency and took a lot of time. From this, we can draw a conclusion: You must back up the image or something. Remember!

2. yesterday, I set up the android development environment for myeclipse. Instead of downloading the SDK, I chose to update the SDK online. Because Google's address is blocked (Sparta ), when I didn't download the SDK, I updated other things (I don't Know). I downloaded the SDK and the supporting ADT plug-in on the 115 network disk, and it was about to close the door in the lab, after the environment is configured successfully, go back. The next morning, I came back to open the Start menu and found that there was an additional software named "pulse Explorer" in my computer, which was never used or installed, without saying anything, you just need to uninstall it. After a while, I started preparing for myeclipse, but was reminded that the shortcut failed. I was so busy opening the installation directory that I was surprised to find that myeclipse was just uninstalled, I updated the SDK when I downloaded the SDK online last night and changed the name. This is not a big deal. The problem is that I deleted all my project files.CodeAh, that's all. Data Recovery failed for a while. At that time, I had a heart hitting the wall,... However, I still cannot bear to hit the issue for better headers in the future. There is only one idea in mind: You must back up the data in the future and you must back up the data.

All of the above are the bloody facts we have personally experienced. I hope I will not make similar mistakes in the future! I have summed up the following: backup is required all the time, especially when we are using computer science and technology to develop and engage in data, be sure to remember the backup! Backup! Complete the backup!
