The present disclosure provides for analyzing data stored in a data protection storage system to determine a prospective storage scheme that provides a more efficient use of storage resources in the data protection storage system. Data can be analyzed to identify a set of data suitable for long term storage in an archive. Data can be analyzed to identify a set of data suitable for deletion to reduce duplicate copies of data, and remove expired data. Protection policies that provide double coverage of data, causing additional inefficient storage of data, can be identified. A prospective amount of freed storage and other savings can be calculated, if all or part of the prospective storage scheme is implemented, where the prospective amount of freed storage and other savings can be displayed to in a report. A prospective storage scheme may also be determined for a client system that stores live data.

Backup application catalog analyzer

A computer-implemented method for indexing backup file metadata may include 1) identifying a request to perform a full backup of a volume, 2) identifying a file metadata index for previous backups of the volume, 3) adding a current key uniquely identifying the file within the full backup and an identifier of the full backup to the file metadata index, 4) comparing the current key to the file metadata index to determine whether the current key is represented in the file metadata index, and 5) adding file metadata to the file metadata index for each file within the volume that is uniquely represented by the current key of the file within the file metadata index. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for indexing backup file metadata

A computer-implemented method for performing a search on a data backup system is disclosed, where at least a portion of the method is performed by a computing device comprising at least one processor. The method includes receiving a search query, performing a search of indexed information stored in the data backup system based on the search query, determining non-indexed information stored in the data backup system related to the search query, and returning results of the performing and the determining.

Search validity in data backup systems

A computer-implemented method for preserving individual backed-up files in accordance with legal-hold policies may include (1) providing at least one legal-hold policy that specifies the manner in which individual backed-up files that potentially relate to legal proceedings are to be preserved, (2) identifying at least one file that has been backed up, (3) identifying at least one legal purpose for preventing deletion of the backed-up file, (4) applying, in response to the identification of the legal purpose, the legal-hold policy to the backed-up file, and then (5) preserving the backed-up file in accordance with the legal-hold policy identified in the file metadata associated with the backed-up file. Various other systems, methods, and computer-readable media are also disclosed.

Systems and methods for preserving individual backed-up files in accordance with legal-hold policies

A method and apparatus for optimizing computer network bandwidth usage to prevent congestion is described. In one embodiment, the method comprises comparing a permissible bandwidth usage with a data transfer rate to produce a comparison result and adjusting the data transfer rate for performing at least one data transfer operation based on the comparison result.

Method and apparatus for optimizing computer network usage to prevent congestion

A computer-implemented method for securely deduplicating data owned by multiple entities may include identifying a plurality of data segments to store on a third-party storage system and, for each data segment: 1) identifying a hash of the data segment, 2) transmitting the hash of the data segment to a central server, 3) receiving an encrypted string that is based on the hash of the data segment from the central server, 4) encrypting the data segment with the encrypted string, and 5) transferring the encrypted data segment to the third-party storage system. Various other methods, systems, and computer-readable media are also disclosed.
