The purpose of this article is to share with you what is a snapshot of a CVM. 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.

Snapshots in the CVM can retain the disk data status at a certain point in time, and are often used for data backup and custom mirroring. Creating snapshots is an extremely important operation, and in scenarios where there is operational risk, snapshots can be created in advance to back up data.

For example, cloud snapshot is the latest CVM data backup method, which copies the system disk and data disk and stores the backup data independently.

Four copies of CVM data are written in real time, combined with multiple snapshot backups to form a backup strategy to cover software and hardware failures, subvert the traditional OPS mode, ensure your data security in an all-round way, and enjoy the convenience brought by real cloud computing.

Features of CVM snapshot

1. Snapshot mount, which is suitable for replacing only some files on disk.

two。 Snapshot rollback, which applies to the overall recovery of all files on disk.

Benefits of CVM snapshot

1. Save multiple snapshots and 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.

two。 Data recovery is flexible. Each CVM snapshot not only supports data rollback, but also supports individual mounting, making it easy to restore individual or partial files. The data recovery task can be submitted at the click of a button, and the operation is convenient.

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

This is what the CVM snapshot is. 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.
