What is the use of ecs snapshots on CVM? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Snapshot provides a convenient and universal data backup method for CVM ecs. Users can realize automatic data backup of disks on CVM by setting automatic snapshot policy. Maintaining the habit of creating snapshots can effectively improve the level of security of website data.

Features of ecs- snapshots on CVM

1. If the user accidentally deletes the system file by mistake, it can be quickly restored by rolling back the snapshot.

two。 Due to lack of server security measures, virus infection, server failure, etc., can return to the normal state of the system in a few minutes

3. When the website is encrypted by blackmail software, if you have taken a snapshot before being attacked, you can successfully avoid extortion and reduce economic losses.

4. Making the system disk into a mirror and the data disk into a snapshot can realize the "replication" of the cloud server while maintaining the original system and data state.

5. In the test CVM environment, if you need to recreate a specific state or condition, it is obviously more convenient to use snapshots without hitting the code repeatedly.

6. When the business system upgrade fails, the cloud snapshot can also be used to restore to the previous point in time without having to reconfigure the system and reconstruct the production environment.

In addition, the cloud snapshot copy can also be used as the source data by the upper layer business. After the snapshot backup of the source data, it can be quickly mapped to other upper layer business, which provides convenience for data mining, report query, development and testing and other applications.
