What this article shares with you is about how to solve the problem of data loss on CVM. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

In the application system, the database is often the core part, once the cloud server database is damaged, it will bring huge losses, so the recovery function of the database is becoming more and more important.

Server storage system

As we all know, hard disk is not only the main device for server data storage, but also a kind of equipment with high technical content and precision manufacturing. At present, the development of server hard disk has reached 10000 or 15000 revolutions per second, and the ordinary SATA hard disk is also very close to this speed. In operation, a small failure may cause physical damage to the hard disk, so the general server uses Raid disk array storage. Strengthen the fault tolerance of the server hard disk.

Server backup mode

In addition to Raid hard disk fault tolerance, for some very important data, we should use other devices to back up from time to time. We recommend network servers built by enterprise and business users, choose tape drives with professional backup software, and make relatively perfect backup programs on a regular basis. If it is an individual user, it is recommended to use an economical CD- ROM/DVD CD as a backup method.

Using recovery softwar

For some simple erroneous deletion or formatting, for not many files, personal technology is good, you can download some recovery software on the Internet to try to restore, of course, before doing it, you can first use Ghost software to do a full disk backup, at the same time, it is best to pick up the slave disk. Of course, if you are not satisfied with the results of your personal recovery, seek a professional data recovery company to operate.

Seek professional and technical help

If you find that the data of the CVM is lost, Qicheng should not operate blindly to reduce the probability of data recovery. You can find formal data recovery company technical support by phone, listen to proprietary advice or ask professional and technical personnel to check. At this point, you can turn off the computer and stop the hard drive from reading and writing data.

Four copies of CVM data are written in real time, combined with multiple snapshot backups, which can effectively solve security threats such as hard disk failure, hard disk damage, drive failure, server failure or human misoperation, software failure, hacker intrusion, virus destruction and so on.

This is how the CVM solves the problem of data loss. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
