TL;DR: Traditional restore workflows can create infrastructure drift in Terraform-managed environments by provisioning replacement S3 buckets or DynamoDB tables that are not in state, according to Commvault. In-place recovery reframes restore design as a configuration integrity problem, not just a backup problem, because the recovery path must preserve declared infrastructure.
Editorial analysis by NHI Mgmt Group, based on content published by Commvault: “Restoring Data While Preserving Terraform State: In-Place Recovery with Clumio Backtrack”.
Key questions
Q: What breaks when a restore creates new resources in a Terraform-managed environment?
A: A restore that creates new resources breaks Terraform state alignment.
Q: Why does infrastructure drift make incident recovery more difficult?
A: Because the incident stops being only a data restoration problem.
Q: How do teams know a restore is aligned with Infrastructure as Code?
A: A restore is aligned when the recovered service still matches the declared Terraform configuration without manual imports or replacement resources.
Practitioner guidance
- Define recovery boundaries in Terraform terms Document which AWS resources must be restored in place and which are allowed to be recreated, then test recovery against declared state rather than only against data durability.
- Test incident recovery against state alignment Run restore exercises that measure whether Terraform state, resource names, and application references remain aligned after data recovery.
- Eliminate manual import steps from the incident path Identify where teams currently import restored resources or rewire endpoints after a restore, and redesign those steps out of the operational runbook.
Bottom line: Traditional restore models can undermine Terraform by creating replacement resources that do not exist in state.

Terraform recovery is a configuration integrity problem, not just a backup problem. When recovery creates replacement resources, the failure is not limited to data loss or downtime. It breaks the declarative contract that Terraform is meant to enforce, so the incident expands into a governance issue about what infrastructure is allowed to exist. Platform teams should read recovery design as part of IaC control design, not as a separate backup concern.
A question worth separating out:
Q: Should teams restore into existing resources or create replacement ones?
A: If the environment is governed through Terraform, restore into the existing resource whenever the service model allows it. Replacement resources can be technically usable, but they often introduce drift and force extra reconciliation work that weakens operational predictability.
