Internet practitioners should know that such a sentence, Bully programmer, he accidentally delete library on foot.
But most of them are self-deprecating joke when a view, similar to this example:
But I did not expect that this happened two days of real delete library events.
Shanghai Micro One of a company operation and maintenance personnel, the company does not know how much hatred is much resentment, last night in the remote directly visit the company's network, angrily deleted a library.
Because a lot of micro-makers with many of their tools, so micro-district were bombed last night to now, a great impact on their income.
After a 36 hours of bloody fighting, micro-AU sent a notice about the failure of the system, but so far still can not recover the data, you look to the announcement.
This announcement can be seen from the following:
1. The staff of the library is not deleted misuse, but man, it is conceivable that with the company is how much hatred, rancor must have been deep;
2. Micro League Tencent investment, so Tencent cloud service use, and Tencent cloud team after bloody battles 36 hours, still can not recover the data, indicating that the problem is very large, some aspects of backup problems, can be said to be fatal of.
3. Data loss a blow to a company how deadly it? If subsequent still can not recover, leading to company closures also said that is no exaggeration.
I do not know what most Internet companies, at least I contacted the internet company attaches great importance to data backup is, even before asked a lot of friends do DBA, many have had experiences delete library, this should be that they life's most difficult to forget the pain, but all misuse, follow very quickly rolled back through the backup.
So in real life, really misuse delete library, but in fact is not necessary on foot, just do the necessary measures can be quickly rolled back.
Done before the DBA Feng teacher, private letter I, seeing this message, simply too pulled, I also take the opportunity to popularize some expertise.
For most Internet companies, will take multiple measures to avoid this catastrophe, this is not to prevent people from intentionally deleted library, but take precautions just in case.
In general, there should be a multi-line data backup, even if was deleted can be quickly restored at least, not more than thirty hours should be no recovery backup, or backup to alleviate serious problems, is very unlikely to take a direct hard disk doing physics restore it.
Then, slightly larger than the size of the company, in general, we all will do at least two or more server room, a computer room off the network to another room can quickly be able to connect, they should only use a Tencent cloud. Then at least we have an alternative cloud services do ah.
还有就是最基本的，针对服务器和数据的操作，管理上有多重审核机制，做角色分级和权限分级。
例如，业务运维、网络运维、DBA 等都不能执行系统层的 rm 指令，系统运维也不能执行数据库的指令，以及不同的角色分配对应的执行权限。
而微盟的一个人直接就能干掉整个数据库，连审核都没有，这就暴漏出了流程和管理上的问题。
而事实上微盟也不是什么小公司了，员工规模不小，还是香港上市公司，能出现这种情况实属不该。
最魔幻的是，微盟今天的股票还涨了。。。
当然了，上面是从公司角度出发的。
从个人角度来说，程序员自身，不管跟公司多大仇多大怨，怒而删库，是最不理智，最愚蠢的行为，这不是英雄行为，这是极严重的违法行为，等待这位运维的只能是牢饭了。
疫情当下，其实很多公司都挺困难，我也陆续听到不少公司为了生存下去，采取了一些措施，比如有的公司裁员，有的公司远程办公期间降薪，有的公司甚至工资发一部分，从员工角度，这当然不合理，但是特殊情况还请特殊对待。
我个人一直告诉星球的球友们说，假如这段时间，真的遇到了降薪或者延迟发放工资情况，如果公司之前待你不错，看好公司未来发展，那么我建议就姑且理解下，跟公司一起扛过这段期间，后续公司发展起来，员工们也都是间接受益者。
当然了，这位删库的同学具体不知道跟公司是什么矛盾，但是无论如何，删库行为是妥妥的违法行为，如果特别严重，造成重大损失，最高甚至可以判死刑的，很多人法律意识淡薄，这里必须提醒下。
最后，愿每个公司都能引以为戒，对数据备份要更重视，而个人，在遇到跟公司矛盾冲突的时侯，不要一时冲动干傻事，要寻求合理合法的解决方案，法治时代，依法办事才是最正确的，法律如果再解决不了，其次可以想办法借助舆论，你们懂得。
愿微盟早日恢复数据，微商们可等不及了。
