Abstract: Disclosed herein are methods, systems, and processes to optimize and manage fingerprint backward compatibility in deduplication backup computing systems. A new fingerprint is generated for a segment object stored in a data container based on a new fingerprinting process. A header file is modified by replacing an old fingerprint for the segment object based on an old fingerprinting process with the new fingerprint. An entry including information indicating an association between the old fingerprint and the new fingerprint is created in a fingerprint map file.

Abstract: A search system obtains a search result comprising an entry. The search result is based on a set of search constraints. The search system generates a hit index based on the search result and each constraint in the set of search constraints. The hit index includes identification information of an element associated with the entry that caused the entry to be included in the search result. The search system updates the search result to comprise an indication of the element associated with the entry based on the hit index.

Abstract: Various systems, methods, and processes for optimizing access to production data in application development and testing environments are disclosed. If an input/output (I/O) operation is a read operation, a storage location on a virtual storage unit at which the read operation is to be performed is determined. Also determined is whether an earlier write operation was performed at the storage location. If an earlier write operation was performed at the storage location, the read operation is performed on one or more virtual data files. However, if the earlier write operation was not performed at the storage location, the read operation is performed on allocated storage space.

Abstract: Various systems and methods are provided for calculating a data criticality score upon ingesting a data object into a data storage system. This data criticality score can be used to control subsequent access requests for the data object. In one embodiment, a computer system receives a data object at a first node comprising a decision engine. The decision engine generates a data criticality score based, at least in part, on one or more inputs related to the data object. After calculating the data criticality score, the system uses the data criticality score to determine whether a given action is allowable for the data object. After determining whether the given action is allowable, the system receives a user request to perform a first action on the data object. The system then determines whether the user request should be granted with respect to the first action, and if allowable, performs the first action.
