Does the CVM back up automatically? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Yes, many CVM generally support automatic backup and manual backup. Take CVM as an example, the data backup method is cloud snapshot.

Cloud snapshots are mainly used in development and test environments. For example, when there is a system problem after upgrading the version, you can use the CVM snapshot rollback to achieve version rollback; if you encounter problems with changing the operating system and migrating business data, you can also restore through the data snapshot; using snapshots in daily backups can greatly avoid the risk of data loss caused by misoperation, attacks and virus intrusion.

CVM leasing provides basic cloud snapshot service by default, which can retain 2 snapshots saved automatically by the system or manually created snapshots. For a more comprehensive and secure data backup solution, it is recommended to upgrade advanced cloud snapshots at a cost of 10 CNY / month.

The Advanced Cloud Snapshot system will retain up to 5 snapshot data each day from the launch date: 4 backups for nearly 4 days and 1 backup within 5-15 days. Users can customize the backup cycle (1-10 days) to easily mount and roll back snapshots.

Note that the cloud snapshot rollback operation is irreversible, and 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 cloud 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.

This is the answer to the question about whether the CVM is backed up automatically. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
