Active Directory Forest Recovery Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disaster recovery methods for Microsoft Active Directory forests are manual, time-consuming, and prone to human error, requiring physical isolation of domain controllers, which leads to prolonged downtime and increased business losses due to the need for manual intervention and potential corruption propagation during the recovery process.
Innovation Solution
A system and method for remotely managing and automating disaster recovery of Active Directory forests, allowing domain controllers to remain online and connected, using a centralized console to orchestrate restoration processes, electronically isolate domain controllers, and prevent unwanted replication, thereby reducing the need for manual intervention and minimizing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual recovery process is used with physical isolation of domain controllers, then recovery can be performed with simple procedures, but recovery time is prolonged and productivity is reduced
Solution Approach 1:
The system enables automated self-service recovery where the forest recovery system automatically performs restoration of domain controllers without requiring manual physical isolation or manual intervention at each domain controller. The system self-manages the recovery process including electronic isolation, restoration, and reintegration phases.
Solution Approach 2:
The patent replaces the mechanical approach of physical isolation (physically disconnecting domain controllers) with an electronic/software-based isolation mechanism. The forest recovery system uses electronic isolation techniques to achieve the same goal without physical manipulation, thereby speeding up the process and enabling remote operation.
2Reliability
If physical isolation of domain controllers is implemented, then corruption propagation is prevented, but manual access to each domain controller is required which is not always possible
Solution Approach 1:
The forest recovery system acts as an intermediary between the domain controllers and the recovery process. Instead of requiring direct physical access to each domain controller, the system mediates the recovery process through automated remote operations, electronic isolation mechanisms, and centralized coordination, making the process accessible even when physical access is not possible.
Solution Approach 2:
The patent substitutes physical mechanical access requirements with electronic remote access capabilities. The system uses software-based mechanisms to isolate and restore domain controllers remotely, replacing the need for physical presence at each domain controller location while maintaining corruption prevention through electronic isolation barriers.
3Reliability
If domain controllers are physically isolated during recovery, then replication corruption is prevented, but domain controllers remain offline during recovery process
Solution Approach 1:
The system performs preliminary electronic isolation of domain controllers before the restoration process begins. This pre-isolation prevents corruption propagation during recovery while allowing the domain controllers to remain in a controlled state rather than being completely offline, reducing overall downtime while maintaining data consistency.
Solution Approach 2:
The patent replaces physical disconnection (which completely takes domain controllers offline) with electronic isolation mechanisms that can maintain domain controllers in a partially operational state. This substitution allows domain controllers to remain accessible for certain functions while preventing corruption propagation, thereby reducing downtime while maintaining data consistency.
4Reliability
If manual recovery steps are repeated on each domain controller, then recovery can be performed, but the process is slow and tedious and prone to human error
Solution Approach 1:
The forest recovery system merges the recovery operations for multiple domain controllers into a single automated process. Instead of performing separate manual steps on each domain controller individually, the system combines and coordinates all recovery operations through a centralized automated system, increasing throughput while reducing human error through elimination of manual repetition.
Solution Approach 2:
The system enables automated self-service recovery where the forest recovery system automatically executes all necessary recovery steps on each domain controller without requiring manual intervention. The automated process ensures consistent, accurate execution of recovery procedures while dramatically increasing recovery throughput compared to manual methods.
Data Source
AI summary
Systems and methods are disclosed for recovering data following a directory service malfunction, such as a forest-wide disaster in Microsoft® Active Directory. In certain examples, a single management console can be used for remotely recovering selected domain controllers in the forest without necessitating direct operator intervention. Multiple domain controllers can be concurrently restored from one or more backup files. Configurations of the system can advantageously eliminate manual intervention with each domain controller, thereby saving significant amounts of recovery time and effort. Also, certain systems and methods can be used to automatically and remotely quarantine corrupt domain controllers so that those individual domain controllers do not replicate with the newly restored environment, while allowing the domain controllers to remain online and in communication with the attached network. Certain disclosed methods further modify recovery procedures based at least in part on the type, and availability of, one or more DNS servers.
