What is the server data disk used for? The configuration of the server contains many sections, and different sections play different roles. The following is mainly to introduce what the server data disk is used to do.
For example, a CVM has two hard disks, one of which is a system disk, which is used to store system data. One is a data disk, which is used to store other data.
If a CVM is compared to a computer, the data disk of the CVM is equivalent to the D disk of the computer, and the system disk is equivalent to the C disk of the computer. When the computer reinstalls the operating system, the content of disk C is certainly gone, but the content installed on disk D is still there and will not be lost.
Therefore, the function of the CVM data disk is that when the CVM initializes the system, the data of the data disk will not be lost with the system initialization.
If you are worried about the loss of the contents of the data disk, you can back up the data locally before reinstalling the system, and upload it to the CVM after installation.
For CVM, 20g data disk is given by default when purchasing, and you can choose the size of the data disk according to your own needs. For users with large data disk needs, you can choose cloud disk or cloud database RDS MySQL.
Cloud disks are mounted in conjunction with elastic CVMs in the same cluster to achieve data storage and copy functions, thus effectively saving manual deployment costs. Three copies of data are written in real time, which can ensure rapid recovery in the event of any copy failure, effectively avoid physical security threats, and the data reliability is as high as 99.9999999%. Support flexible expansion at any time, cost-effective choice.
