When you take an EBS snapshot in AWS, you’re backing up individual volumes, not the entire EC2 instance. Each snapshot captures the state of that specific disk—so if your instance has multiple EBS volumes (root, data, logs), you’ll need to snapshot each one or use an AMI creation process, which under the hood snapshots the root volume and registers a new instance image. Early in my career I was surprised by this too: one missed volume means missing data. At AceCloud, we simplify this by offering snapshot orchestration across all attached volumes and optional image-level backups, ensuring you never lose part of your stack.
