Abstract: A file system that operates on an underlying volume that has multiple tiers, each tier including a particular trait set. Upon creating or otherwise identifying a file system namespace (such as a directory or file) that is in a volume or that is to be included within the volume, a storage trait set to be applied corresponding to the file system namespace is identified. Then, the storage trait set is compared against the trait sets for the multiple tiers to identify a tier into which to store the file system namespace. The file system namespace is then caused to be stored within the identified tier. Thus, the file system is provided with a volume that has multiple tiers (each having different trait sets) to choose from in storing files.

Abstract translation: 对具有多个层的底层卷进行操作的文件系统，每个层包括特定的特征集合。 在创建或以其他方式识别卷中或要包含在卷内的文件系统命名空间（例如目录或文件）时，识别与文件系统命名空间相对应用的应用程序的存储特征。 然后，将存储特征集与多层的特征集进行比较，以识别存储文件系统命名空间的层。 然后将文件系统命名空间存储在所识别的层中。 因此，文件系统被提供有在存储文件中具有多层（每个具有不同特征集）的卷可以选择的卷。

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.
