How to back up the server
How does the server back up? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.
The server has a snapshot of the automatic backup function, and there is a snapshot function in the control center of the CVM, which is used for automatic backup and recovery.
Generally speaking, Aliyun snapshots automatically back up system disks and data disks every day. If the server is attacked, you can borrow the snapshot feature to quickly restore each drive letter. Users can also create snapshots themselves, but the shortcomings of Aliyun Snapshot feature are obvious, which cannot backup and restore some data. In addition, the concept of disaster recovery cannot be realized.
In contrast, the cloud snapshot mount feature is suitable for operations that only need to replace some of the files on disk. Cloud snapshot is the latest CVM data backup method, which copies the system disk and data disk completely and stores the backup data independently.
Snapshot mount: suitable for replacing only some files on disk. Snapshot rollback: applies to all files on the recovery disk as a whole.
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.
CVM system disk and data disk can create snapshots separately and separate backups, which meets the flexibility of data backup and recovery. Snapshot offline storage does not occupy customers' disk space, even if the cluster system fails, it does not affect the security of snapshot data.
Each cloud snapshot not only supports data rollback, but also supports individual mounting, making it easy to recover individual or partial files. The user can submit the data recovery task with one click, and the operation is convenient. Therefore, the backup function is very powerful and convenient for cloud server rental.
