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

Snapshot is a data backup feature of many mainstream cloud servers, which is used to restore data in the event of a server failure and restore system data to a certain time before the error occurs.

Take a CVM as an example. Cloud snapshot is a way to back up the data of the CVM, which copies the system disk and data disk completely, and stores the backup data independently. Four copies of CVM data are written in real time, and then combined with multiple snapshot backups.

Cloud snapshots make fully available copies of system disks and data disks, and store backup data independently. Separate backup, snapshot offline storage, does not occupy the customer's disk space, even if the cluster system failure, does not affect the snapshot data security.

Save multiple snapshots

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

Custom backup frequency

Advanced cloud snapshot service supports setting the automatic backup frequency of the system (1-10 days), providing users with more choices and meeting more special needs.

Each snapshot of a CVM not only supports data rollback and overall recovery of all files on the disk, but also supports individual mounts, which can easily restore individual or partial files. The data recovery task can be submitted at the click of a button, and the operation is convenient.

This is what the snapshot backup of CVM 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.
