Agent Service Memory Simulation for Secured Bare Metal Restore
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current backup systems face challenges in efficiently performing incremental backups of bare metal recovery (BMR) and system state recovery (SSR) objects due to the complexity and interdependencies of system data, leading to increased storage costs and backup times, as well as limitations in accurately reporting system asset sizes and user experience issues during restoration.
Innovation Solution
The implementation of automated backup recovery techniques using a data protection backup system that includes a management console, data protection agents, and a storage system, which utilize snapshot technology and incremental backup tagging to identify and backup changed system objects, and dynamically promote user data writers to system writers for comprehensive backup and recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full backup is performed for BMR or SSR objects, then data protection is ensured, but storage costs and backup time increase significantly
Solution Approach 1:
The patent segments the backup process into full backup and incremental backup phases. The first backup is a full backup that establishes a baseline, while subsequent backups are incremental, only capturing changes since the last backup. This segmentation allows the system to maintain data protection while significantly reducing storage requirements and backup time for routine operations.
Solution Approach 2:
The patent performs preliminary action by conducting a full backup first to establish a complete baseline of system data. This preliminary full backup enables all subsequent backups to be incremental, as the baseline is already in place. The preliminary action resolves the contradiction by setting up the infrastructure for efficient ongoing backups without compromising initial data protection.

3Reliability
If manual network configuration is required during BMR restore, then security control is maintained, but user experience deteriorates
Solution Approach 1:
The patent implements self-service by enabling the target system to automatically obtain network configuration parameters (such as IP address, subnet mask, gateway, and DNS settings) from a DHCP server during the restore process. This eliminates the need for manual network configuration by the user, dramatically improving user experience while maintaining security through controlled automated processes.
4Reliability
If backup products lack support for incremental BMR or SSR backup, then comprehensive protection is achieved, but storage costs and backup time increase

The first backup is a full backup that establishes a baseline, while subsequent backups are incremental, only capturing changes since the last backup.

Data Source
AI summary
A target host is booted into a preinstallation environment. A request to register as a recovery agent is issued from a REST API of the target host to a backup management server. A TLS certificate to establish a secure channel is received from the backup management server. A request identifying a backup copy to be stored on the target host is issued from the REST API of the target host and over the secure channel to the backup management server. Credentials required to access a backup storage at which the backup copy is stored is received. Using the credentials, the backup copy is retrieved from the backup storage.
