Automated Directory Link Restoration from Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Restoring directory service objects from backup often requires manual recreation of links, which is inefficient and prone to errors, as existing methods do not automatically restore links between objects.
Innovation Solution
A method and system for automatically restoring links to a directory service object by detecting the need for forward links in a backup's link table or corresponding backward links, allowing for the creation of forward links during the restoration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual directory service objects are restored from backup independently, then restoration speed and simplicity are improved, but link restoration completeness deteriorates
Solution Approach 1:
The system performs preliminary analysis of the backup data to identify all forward links pointing to the object being restored and all backward links within the object before restoration begins. This pre identification ensures that all link relationships are captured and can be automatically reconstructed after restoration, resolving the contradiction between fast individual restoration and complete link recovery
Solution Approach 2:
The patent introduces an intermediary mechanism that analyzes the backup metadata to identify link relationships (forward links from other objects and backward links within the object) and automatically recreates these links after restoration. This intermediary link reconstruction process enables individual object restoration while maintaining link completeness
2Reliability
If manual recreation of links is performed after restoration, then link restoration completeness is improved, but operational efficiency deteriorates
Solution Approach 1:
The system implements self-service by automatically analyzing the backup data to identify all link relationships (both forward links from other objects and backward links within the restored object) and autonomously recreating these links after restoration. This automation eliminates the need for administrator intervention in link recreation, simultaneously achieving complete link restoration and high operational efficiency
3Manufacturing precision
If manual link recreation is required, then link accuracy can be controlled, but error susceptibility increases
Solution Approach 1:
The system uses feedback by analyzing the backup metadata to identify existing link relationships and using this information to guide the automatic recreation of links. The system verifies link relationships by checking both forward links in the backup and backward links in the restored object, ensuring accuracy while eliminating manual errors through automated verification
Data Source
AI summary
Various methods and systems for automatically restoring links to a directory service's object when that object is restored from backup are disclosed. One method involves receiving user input selecting an individual directory service object for restoration from backup; restoring the directory service object from the backup; and automatically creating a forward link to the directory service object from a source object. The need to restore the forward link can be detected by either finding the forward link in a copy of the link table within the backup or finding a corresponding backward link in an attribute of a backed-up copy of the directory service object.
