The purpose of this article is to share with you about the data security of cloud servers. 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.

Data is an important means of production for an enterprise, and the loss of key data may be a fatal blow to the enterprise. Because the "data disaster" is random, in order to avoid bad results, cloud servers generally use a variety of strategies to "insure" website data.

Cloud snapshot service can be used for online data backup and recovery, providing storage users with a feasible data access channel. For all online storage systems, snapshots are an indispensable function in order to protect data security more effectively and avoid potential risks.

Take the CVM snapshot feature as an example, you can make fully available copies of the system disk and data disk, and store the backup data independently. The advantages of cloud snapshot feature include simple configuration, independent backup, multi-copy support, flexible data recovery, customizable backup frequency, and so on.

Simple configuration: snapshot configuration is very simple, and in most cases, the impact of snapshots on the performance of block storage Imax O is less than 10%. Users are not aware of the business during snapshots, and data snapshot backups are supported at any time.

Backup independence: CVM system disk and data disk create snapshots separately and separate backups to meet the flexibility of data backup and recovery. Snapshot offline storage does not occupy customers' disk space, even if the cluster system fails, it does not affect the security of snapshot data.

Multi-copy support: the CVM snapshot feature can provide up to 5 fully available snapshots, including the latest data backup in the early hours of the day, and older data backups within a maximum of 15 days, effectively solving the backup coverage problem.

Flexible data recovery: each snapshot of a cloud computing server not only supports data rollback (overall recovery of all disk files), but also supports mounting separately to easily restore individual or partial files. The data recovery task can be submitted at the click of a button, and the operation is convenient.

Custom backup frequency: advanced cloud snapshot service supports setting the automatic backup frequency of the system (1-10 days), providing users with more choices to meet more special needs.

Is this the data security of the CVM? 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.
