How to protect the data security of CVM? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

How to protect the data security of CVM?

Every enterprise will have its own server, and more and more enterprises choose to go to the cloud and store some important data in the cloud. Therefore, protecting the security of cloud server data has become a very important thing for enterprises.

Back up data regularly

The significance of data backup is that when network attacks, virus intrusions, power failures or operation errors occur, the original system can be restored completely, quickly, simply and reliably, and the normal operation of the system can be ensured within a certain range. In terms of data backup, enterprises should regularly carry out tape backup, database backup, network data backup and update, remote mirroring operations, etc., as well as multiple data backups.

Establish a disaster recovery center

In the face of regional and devastating disasters such as earthquake and fire, only data backup can not be recovered. at this time, it is necessary to have a disaster recovery center to make a remote backup of the data to ensure that the original data will not be lost or destroyed. The recovery time of data disaster recovery is relatively long, and the main methods are real-time replication, timing replication and store-and-forward replication. Of course, data backup is the most basic, there is no data backup, any disaster recovery is of no practical significance.

Raid disk array storage

To put it simply, multiple independent hard drives are combined in different ways to form a hard disk group, which provides higher storage performance and data backup technology than a single hard disk, thus greatly enhancing the security of data. The different ways to form a disk array are called raid levels, and choosing the appropriate raid level according to the actual situation can meet the user's requirements for storage system availability, performance, and capacity.

Do not operate or modify blindly

Human misoperation is an important reason for data loss of CVM. Sometimes files are accidentally deleted, or misformatted, mispartitioned, miscloned partitions, lost partition table information (MBR), etc., poor handling may paralyze the entire server.

In addition to not modifying or blindly manipulating the server, it is necessary to set reasonable permissions, such as giving "edit" rights to users responsible for daily updates. This can greatly reduce the misoperation of non-professionals and improve the data security of the server.

This is the end of the answer to the question on how to protect the data security of the CVM. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
