What this article shares with you is about how to recover the replacement data of CVM. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

When you change a CVM, you are most worried about your own data on the server. After all, data is an important virtual asset for an enterprise. Next, we will introduce the migration operation of CVM replacement data.

Take a CVM as an example. If you transfer data between multiple CVMs in the same cluster, you can use the cloud disk as a transit. After unmounting the cloud disk of the original host, you can mount it back to the target host. Cloud disk can back up additional data, and in special cases (such as when the server is about to expire and there is no need for renewal), important data can also be temporarily backed up to the cloud disk to cooperate with the custom image feature to avoid file loss.

Partial data migration of private network CVM:

1. Through the internal IP remote desktop mode

Each elastic CVM under the same account is assigned an internal IP to communicate with other machines under the current account. For example, to transfer data from host A to host B, you can use internal IP.

1) Log in to Host B-start-run enter mstsc- to enter remote login information for host A, and click "Local Resources"-details-check driver.

2) after logging in to the remote desktop of host A, you can see the local disk of host B, and the data can be copied directly between the two host disks.

3) find the data to be transferred (you can package all the data in host A first)-copy-store in host B directory-paste.

Note: if you are in a different cluster data center, you need to use the public network IP for remote connection. The transmission may be slow. It is recommended to download it by web.

two。 Through the web way

Compress and package the data that needs to be transferred and place it in the root directory of a site. Log in to host B-enter "http://www.xxx.com/xxx.rar" in the browser or using the download tool to download.

3. Through the ftp way

Install ftp software on the new server, connect directly to the host ftp site, and download data through ftp connection.

The above is how to recover the CVM replacement data. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
