Any snapshot taken by Tessell is a storage snapshot in the underlying cloud infrastructure, and hence the same goes for automated snapshots as well. If AWS is the cloud of your choice, then the snapshot will be an EBS snapshot. If it’s Azure, then it will be an Azure managed disk snapshot.

These storage snapshots are stored in the same region where the service is running. This is often called the production boundary. Each snapshot is retained as long as it’s needed to honor the RPO SLA. For example, if your service needs a point-in-time recovery for 2 days, then the automated snapshots will be kept only for the last two days. Any older snapshots will be purged.
