I've been desperately trying to find a way to backup my AWS EFS file system to S3, but cannot seem to find one.
There's several EC2 instances running all having access to the mentioned EFS. In order to reduce traffic, I already tried launching a Lambda Function, which SSHs to the EFS instances and runs "aws s3 sync ...". Unfortunately SSHing from Lambda services doesn't seem like a good production ready solution.
What I've also tried was adapting DataPipeline, but launching additional instances just for backups seems like a hassle, too.
Isn't there some easy way of backing up EFS to S3?
Any suggestions appreciated.
