    Abstract: Techniques are provided for a maintaining and utilizing a file index and a file version index. Metadata may be evaluated to identify constant attributes and modifiable attributes of files. A file index of a file catalog may be populated with the constant attributes. A file version index of the file catalog may be populated with the modifiable attributes as file versions of the files. In response to receiving a request for a file, the file index and the file version index are evaluated to identify a location of the file within a data source. Access to the file at the location within the data source is provided.

    Abstract: Methods, non-transitory machine readable media, and computing devices that provide file backup catalogs with improved scalability are disclosed. With this technology, a sequence number is incremented and an entry for a snapshot associated with obtained metadata for the snapshot is generated. The snapshot entry comprises a snapshot identifier for the snapshot and the incremented sequence number. A current version flag is then set in another entry for a file associated with a create event identified in the metadata. The file entry includes a file identifier for the file, a create attribute comprising the incremented sequence number, and a delete attribute. The file and snapshot entries are then inserted into indice(s) in a catalog database. Based on the schema of the indice(s), this technology provides a lightweight, elegant, and highly scalable catalog that more efficiently facilitates full path global file search and restore functionality with reduced resource utilization.
