Can CVM snapshots be backed up automatically? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Can be automatically backed up, such as cloud snapshots. Generally speaking, the image of the CVM also has a backup feature, but the image needs to be created by the user in advance, and the cloud snapshot is the automatic backup feature of the CVM system.

Currently, major CVM operators provide backup services for cloud snapshots, such as Aliyun, Tencent Cloud, Baidu Cloud, Huawei Cloud and so on.

Cloud snapshot is the data backup method of CVM, and the server system automatically backs up the snapshot of data. As long as the user is operating during the snapshot, the data can be rolled back to before the server failed. Let's take this as an example to explain this function in detail.

The basic cloud snapshot has a 2-day cloud snapshot by default. A cloud mirror backup is carried out every morning. If a problem is found on the same day, it can be rolled back and restored immediately, and the cloud snapshot can be mounted to restore a single file.

There are 5 advanced cloud snapshots, with at least the last 5 days of backup. Users can also customize the automatic backup frequency of the system. According to the set interval frequency, the cloud snapshot time of 5 backups is different, so the longer it takes to obtain backups.

Four copies of CVM data are written in real time, combined with multiple snapshot backups, forming a backup strategy to cover software and hardware failures, subverting the traditional operation and maintenance mode, and ensuring users' data security in an all-round way.

In addition, the enterprise itself should also do a good job in personnel management and server data maintenance. The important thing is to do more backups at ordinary times, such as full backup, differential backup, remote / local backup and so on, so that we can save the data at the critical moment of problems and avoid more losses.

After reading the above, have you mastered the method that CVM snapshots can be backed up automatically? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
