At Christmas, I received a call. A very important customer encountered some problems in using the product. The main reason was that when the Administrator transferred the sqlserver database, the database was overwritten and all the data was lost, oh, it's Christmas.
After making a phone call for more than an hour, I tried a lot of methods and eventually failed because the customer always wanted to push the responsibility to us, what I thought at the time was that it was more important not to take responsibility and try to avoid losses.
Because it was a weekend, the mobile phone of the employee closest to the scene of the company was in arrears, so we lost 1st time to save the data. When the risk comes, the response mechanism is so weak.
I had been dreaming about data recovery for a long time last night. Haha, maybe computers will be very thin, because the phone will be called at any time.
After all, the boss's phone number will come. Although there is no criticism, it is also not satisfied. I hope it can be solved through technical means.
I have always been paying attention to moving away from the data that is mistakenly overwritten after recovery. There are multiple methods of failure...
Two colleagues arrived at the scene in the morning, tossing for one morning, and finally gave me a call that surprised me so much.
In the past, our system usually generates two copies of data on the server and the client. The client is used as the cache data. After the user completes the operation, the data is transmitted to the server, the local file is not destroyed.
However, in the new version, some users have proposed that if local data is tampered with, the security cannot be guaranteed. Therefore, we use the local cache deletion policy after uploading.
Thank God that the old version is used and the cache has not been deleted.
The boys collected the cache data back. I did a test and got it. Although it cannot be guaranteed to be 100%, a few small pieces of data will be lost at most.
At this time, I am in conflict. Data is important or security is important. You may have to decide.
After Christmas is a carnival. I hope the phone will not remind me at this time. I really appreciate these brothers. Otherwise, I may still be at the tip of the corner. Why is it so difficult to think about it in another way?
Have fun...
