I am running a neo4j database from an EC2 instance on on AWS. Unfortunately, I recently lost my personal hard drive, and now I can no longer access my PEM (private key) file. That means that I can no longer SSH into the instance. AWS does have a way of changing the key pair for an EC2 instance where the root device is type ebs, but the data in directories /dev/sdb and sdc will be lost.
I have no way of backing up that data, because again I can no longer SSH in. So the question is, if I delete those directories, will I lose any of the data in the database?
