This article uses easy-to-understand examples to introduce how to create web page snapshots using ecs cloud servers. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Snapshot is the data backup method of many ecs CVM. Taking CVM as an example, basic cloud snapshot service is provided by default, and 2 snapshots automatically saved by the system or manually created snapshots can be retained. For a more comprehensive and secure data backup solution, you can upgrade to advanced cloud snapshots.

Create a cloud snapshot on ecs CVM

Activation process: log in to the website member account-member Center-Server Management-corresponding CVM management-Cloud Snapshot function-create snapshot or activate advanced cloud snapshot

The fee for advanced cloud snapshot feature is 10 yuan / month. The system will retain up to 5 snapshot data every day from the activation date, including 4 backups of nearly 4 days and 1 backup within 5-15 days. Users can customize the backup cycle (1-10 days) to easily realize snapshot mount and rollback operations. The data recovery task can be submitted at the click of a button, and the operation is convenient.

Use of ecs CVM cloud snapshot

When using CVM snapshots, it should be noted that the creation of snapshots temporarily reduces the performance of block storage Iripple O (the general performance difference is less than 10%) and slows down briefly. It is recommended that users avoid business peak to create them. Snapshots are not recommended if the CVM provides time-sensitive services, or if the performance / availability of the storage space is critical.

Although snapshots are generated quickly and take up less space, if the original data is corrupted, the snapshot rollback cannot recover the correct data, while backups can. Therefore, for the sake of data security, snapshots and backups should be used together when a CVM is leased.

The cloud snapshot rollback operation is irreversible. After the rollback is complete, the disk will restore the state it was in when the snapshot was created (including partitions, file systems, data). In general, the reliability of CVM data based on snapshots and distributed storage is more than 99.99%. However, if there is very important data, it is recommended that users make a separate backup to ensure that it is foolproof.

So much for sharing about how to create web page snapshots using ecs 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.
