Classification: CPC G | IPC G

Claim 14:
15. A method for restoring data processing capabilities in the event of an interruption of a computing system, the method comprising:
storing indexes of data utilized by the computing system using a user catalog program,
creating SMF audit records that track user catalog activity as SMF data,
intercepting portions of the SMF data over a timeline, the portions corresponding to creation, deletion, and modification of data files,
cataloging the intercepted portions of the SMF data over the timeline in a virtual catalog, and
after an interruption is detected, restoring data processing capabilities of the computing system based on a combination of the stored indexes and the intercepted portions of SMF data, wherein after the interruption is detected:
a respective user catalog activity record of the user catalog activity is absent from a respective stored index of the stored indexes, but the absent user catalog activity relates to creation, deletion, or modification of data files for which corresponding information about the creation, deletion, or modification is present in the virtual catalog,
the respective catalog activity record of the catalog activity accounting for a location of a dataset that has been deleted and/or altered was present in the respective stored index at a prior time when a volume backup occurred, and
restoring data processing capabilities of the system includes configuring the respective catalog activity record to be present in the respective stored index of the stored indexes as the respective catalog activity record was present at the prior time.
