⁠EFS Snapshot Tool

⁠Overview

Presently, there is no way to 'snapshot' an EFS backed volume on AWS. To overcome this, we have created a script which will effectively:

• Pull a list of all EFS volumes on the account, and then for each volume, it will:
  • Create an ephemeral 'Key Pair', 'Security Group', EC2 Instance', and EBS volume (calculated to be slightly larger than the EFS volume it will be backing up).
  • Copy the EFS data to the newly created EBS Volume
  • Snapshot the EBS Volume
  • Destroy the Key Pair, Security Group, EC2 Instance, and EBS volume

⁠Before Running...

Before running, AWS credentials/config, need to be provided.

⁠AWS Credentials

• Copy the 'credentials' and 'config' AWS files that are typically found in $HOME/.aws into the folder /aws-credentials. If you do not havev these files, please see here⁠

⁠How to run

⁠Docker Build

docker build . -t <<BUILD_NAME>>:latest

⁠Docker Run

docker run -it -v $(pwd)/aws-credentials:/root/.aws <<BUILD_NAME>>:latest

⁠Note

Presently this script is only built to work for eu-west-1
