I was thinking about switching from AWS Elastic Block Storage to AWS Elastic Filesystem (mainly for the easy scalability, also shareable storage seems nice).
At the moment I have one debian EC2 instance with one EBS volume. What’s the easiest way to transfer my data from EBS to EFS?
The fastest way to achieve this is mount that EFS file system to your EC2 instance with EBS and then transfer the data from your EBS to EFS.
Follow this guide for mounting the EFS to your EC2 instance. https://docs.aws.amazon.com/efs/latest/ug/mounting-fs.html
