How can a CVM restore backup data? 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.

Nowadays, many CVMs have cloud snapshot feature, which is used to restore backup data and other operations. Cloud snapshot is a backup method, the so-called snapshot is to back up the data of a certain disk at a certain point in time. It can capture the status, data and hardware configuration of running CVM, and is often used in disaster recovery, persistent backup, data migration and other scenarios.

Data backup

Using snapshots in daily CVM data backup can greatly avoid the risk of data loss caused by misoperation, attacks and virus intrusions. Create snapshots for specified disks and use data as the basic data of other disks. Disaster recovery in the same city and remote locations can also be achieved. In addition, through the snapshot feature of the CVM, you can quickly replicate the system environment between different disks, improve the efficiency of batch deployment of similar instances, and so on.

Cloud snapshots make fully available copies of system disks and data disks, and store backup data independently. Four copies of CVM data are written in real time. Combined with multiple snapshot backups, a maximum of 5 fully available snapshots can be provided, including the latest data backup in the early hours of the day and older data backup within a maximum of 15 days, effectively solving the backup coverage problem.

Data recovery and restore

Using cloud snapshots, you can quickly and easily restore the CVM to its previous state. Therefore, CVM snapshots are also mainly used in development and test environments. For example, when there is a system problem after upgrading the version, you can use snapshot rollback to achieve version fallback; change the operating system and migrate business data to encounter problems, or you can restore it through data snapshots.

The recovery of CVM leased data is flexible. Each snapshot not only supports data rollback, but also supports individual mounting, making it easy to recover individual or partial files. The data recovery task can be submitted at the click of a button, and the operation is convenient. The Advanced Cloud Snapshot service supports setting the automatic backup frequency of the system.

After reading the above, have you mastered how the CVM can restore backup data? 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!
