Systems and methods for indexing backup content

摘要

A computer-implemented method for indexing backup content may include identifying a backup of live data. The computer-implemented method may also include identifying a content index that indexes at least a part of the live data. The computer-implemented method may further include identifying a set of files in the backup that correspond to a set of files indexed by the content index. The computer-implemented method may additionally include indexing the content of the set of files in the backup based on the index information of the set of files indexed by the content index. Various other methods, systems, and computer-readable media are also disclosed.

1. A computer-implemented method for indexing backup content, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:
indexing a backup copy of live data by using an existing content index that covers the live data by:
identifying the backup copy of the live data;
identifying the existing content index that indexes at least a part of the live data, the live data comprising a primary copy of data that is currently in use;identifying a set of files in the backup copy that correspond to a set of files indexed by the existing content index;indexing content of the set of files in the backup copy based on index information of the set of files indexed by the existing content index by adding to an index entry in the existing content index, for each file in the set of files, a location of a corresponding file in the backup copy such that each entry in the existing content index points to both live and backup instances of datad.
