Directory Service Backup Segmentation for Predictive File Recovery

The patent segments a large backup asset into multiple sub-assets based on directory service types (e.g., Active Directory, LDAP). Each sub-asset contains data from specific directory services and can be independently managed and restored. This segmentation enables selective recovery of critical directory service data without requiring restoration of the entire backup asset, thereby reducing recovery time while maintaining manageable organization through categorical grouping.

The patent applies different retention policies to different sub-assets based on their directory service type and criticality. Critical directory services (e.g., Active Directory) receive longer retention periods and higher priority, while less critical services receive shorter retention. This local quality approach optimizes storage resource allocation by retaining only the necessary amount of data for each category, reducing overall storage consumption while maintaining simplified policy management through type-based categorization.

The patent segments the backup asset into sub-assets corresponding to different directory service types, enabling targeted security scanning of only relevant sub-assets. Instead of scanning the entire backup asset, the system identifies and scans only the sub-assets that contain potentially affected data based on the security threat context. This segmentation maintains comprehensive security coverage for critical areas while significantly reducing scanning time and computational resource consumption by excluding irrelevant sub-assets from the scan.
