Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [CA Backup and Restore Windows PowerShell cmdlets](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/component-updates/CA-Backup-and-Restore-Windows-PowerShell-cmdlets) from Microsoft supports the following bounded statements: - At Introduction below H1, Microsoft states: “However, it has not undergone the same editing passes, so some of the language may seem less polished than what is typically found on TechNet.” The research record locates this support at Introduction below H1. - At Overview, Microsoft states: “The ADCSAdministration Windows PowerShell module was introduced in Window Server 2012.” The research record locates this support at Overview. These statements are the factual basis for this document. Do not extend them into a broader assurance. Review forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles only where the source and recorded environment align. ## What the source does not establish The cited page and retained statements do not establish the current state of any DSE or customer environment, prove that the documented configuration is applicable, or authorize a production change. Confirm supported versions, dependencies, and the current live source before use. The citation is not a substitute for observed state, authorization, compliance evidence, or dependency health. Examine Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity before translating the source into an operational decision. ## Applicability questions - For source statement 1 at Introduction below H1, which observable configuration, record, or test can confirm applicability here? - For source statement 2 at Overview, which observable configuration, record, or test can confirm applicability here? - Within forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles, which versions, roles, and configuration states define the review population? - Could Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity invalidate the test, hide a failure, or change applicability? - Who owns the decision, and which observation requires stopping, escalation, or rollback? ## DSE recommendation: DSE recommends using the cited source as the evidence anchor for this decision. Start with applicability, then compare the observed state with the cited source. Record the source location, examined part of forests, domains, controllers, directory partitions, trusts, sites, replication links, service accounts, and delegated roles, observed and expected states, owner, and reason for deviation. If the review warrants change, use a bounded implementation with prerequisites, test population, monitoring, abort criteria, and a rehearsed reversal. Sequence checks for Windows DNS, time synchronization, network reachability, PKI, backups, virtualization safeguards, and privileged identity and sanitize protected material before retention. ## Verification and evidence Evidence should let another reviewer reproduce this decision. Retain observations beside the traced locations Introduction below H1; Overview. Favor directory and policy exports, replication and locator tests, event logs, trust state, role ownership, and controlled authentication tests, linked to stable identifiers, time, and operator. Label this evidence set DSE-20260827-053 so observations, approvals, exceptions, and later rechecks cannot be substituted from another source review. Record the decision even when no change is made, including uncertainty and the next trigger. Use safe testing conditions for disruptive work, preserve rollback proof, and revisit the conclusion after relevant platform, dependency, vendor, or ownership changes. ## Official references - [CA Backup and Restore Windows PowerShell cmdlets](https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/component-updates/CA-Backup-and-Restore-Windows-PowerShell-cmdlets) — Microsoft ## Primary reference - Name: CA Backup and Restore Windows PowerShell cmdlets - Authority: Microsoft Learn - URL: https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/component-updates/CA-Backup-and-Restore-Windows-PowerShell-cmdlets - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Stage CA Backup and Restore Windows PowerShell cmdlets with AD/DNS rollback checks,” DSE Security, https://update.dsesecurity.com/updates/stage-ca-backup-and-restore-windows-powershell-cmdlets-with-ad-dns-rollback-checks/ Publishing principles: https://update.dsesecurity.com/updates/dse-updates-editorial-methodology/ Usage and citation policy: https://update.dsesecurity.com/usage/ Copyright © 2026 Detection Systems & Engineering.
