Abstract: The present disclosure provides techniques for performing a file lookup. An example of a system includes a file system corresponding to one or more physical storage devices, a database that stores metadata corresponding to files in the file system, and a search module. The reporting framework receives search criteria for a file lookup, generates a complex query based on the search criteria, sends the query to the database, receives search results corresponding to the query, and generates a search report based on the search results. The search criteria include two or more search tokens and one or more Boolean operators.

Abstract: A source volume and a copy volume are stored, where the copy volume contains data that has been modified by writes to the source volume. In response to a write to a particular location and resource volume, a deduplication data structure is checked to determine whether the copy volume contains data that is the same as data in the particular location. In response to determining from the deduplication data structure that a copy volume contains the same data as the data in the particular location, a reference to the first location of the copy volume storing the same data is added instead of repeating storing of the data of the particular location in the copy volume.
