AWS drs: Note: Failback Client supports x86_64 servers only

Service: drs · 2026-09-27 · Documentation low

File: drs/latest/userguide/failback-performing.md

Summary

Adds a note clarifying that the Failback Client supports only x86_64 servers and that arm64 source servers must fail back within AWS.

Security assessment

This is a functional/compatibility clarification about processor architecture support for failback; it has no security implications.

Evidence

The Failback Client supports `x86_64` servers only. For `arm64` source servers, fail back within AWS. See [Performing a failback with Elastic Disaster Recovery](./failback-performing-main.html).
