Copying Data Between Instances

07/30/202681854 views

For example: You need to copy certain data from Instance 1 in Beijing Zone A to Instance 2 in Inner Mongolia Zone A.

So:

Step 1 An instance 2 was launched in Region A of Inner Mongolia. Its SSH command is: ssh -p 66666 region-3.webcal.com

Step 1 Launch an instance (Instance 1) in Zone A, Beijing, and then execute the following in the terminal of Instance 1:

⚠️The parameter in the command below is -rP, not -rp

scp -rP 66666 /root/webcal-tmp/xxxxx region-3.webcal.com:/root/webcal-tmp/

In other words, remotely copy the data from Instance 1 in Zone A in Beijing to Instance 2 in Zone A in Inner Mongolia.
