In aspects, a change journal is read to determine changes that have occurred to objects of a file system. From these changes a data structure is created to capture path information and collect changes for each object. Where the data structure is insufficient to identify a complete path, the live file system is consulted. After the data structure is complete, a data protection engine uses the data structure to update a catalog at least to provide the capability to view the namespace of the protected objects at one or more times covered by the catalog."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"File system backup using change journal","description":"Aspects of the subject matter described herein relate to backups and change journals.
