Abstract: Aspects of the subject matter described herein relate to data protection of files that may include both content and embedded metadata. In aspects, an indication that a file has changed is received. If the content has changed, the entire file or just the content may be backed up. If the metadata only has changed, the metadata may or may not be backed up, depending on implementation. Instead of parsing the file to determine the exact size and positioning of the metadata within the file, the file may be divided into three portions: a head portion, a middle portion, and a tail portion. Hashes of these portions may then be used to determine whether the metadata and/or content of the file have changed.

Abstract: Aspects of the subject matter described herein relate to backups and change journals. 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.
