I have about 30 AWS instances, each running SQL Server. I want to back them up onto an AWS EBS Volume or S3 bucket - using a free solution.
I was thinking of creating a large volume and mapping each of the instances to it, to backup directly onto it, or to create local backups, which I can then copy onto the central volume. Would this be a good solution?
Another solution would be to set up local backups, then create scripts to FTP the backups to a central server (or copy to S3 https://aws.amazon.com/getting-started/tutorials/backup-to-s3-cli/).
