This article uses easy-to-understand examples to show you how to create a snapshot on a CVM. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Snapshot is a backup method for many kinds of CVM, which provides security for user data. Let's take the cloud snapshot as an example to show how to create it.

Create a cloud snapshot

Log in to the website account, go to Business Management-Server Management-manage, and then click Cloud Snapshot.

If you want to reinstall the win2008 system as a win2012 system to test a function, you can create a snapshot, then reinstall the system, and then use the snapshot rollback to restore to the current data. Create snapshots of data disks and system disks, which are generally not used. The interval before and after manually created snapshots is 8 hours.

Activate advanced cloud snapshots

Generally speaking, only the last two snapshots are available by default. After enabling advanced cloud snapshots, 5 snapshots will be retained. 1-4 are backups for the last 4 days, and 5 are backups for the last 5-15 days. You can set the backup frequency of snapshots after activation.

Snapshot mount and rollback

Mounting a disk is equivalent to attaching a USB disk, in which there is backup data at the corresponding time, which can be targeted to copy the required data

Linux needs to mount partitions by command. To avoid confusion, if you are not familiar with the linux system, do not mount the system disk with the data disk. Snapshot rollback is a full recovery of snapshot data. The current data is overwritten and cannot be started when the system is damaged or no current data is required.

This is the end of how to create a snapshot on the CVM. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
