Abstract
Example apparatus and methods create and maintain a functional mirror of file system metadata for an active file system. The functional mirror may be implemented as a set of feature vectors in a feature space stored in a spatial database that allow a journal functionality for information received from the active file system. Mirror creation and maintenance can operate in parallel. The functional mirror may be created primarily using a systematic, system-wide, multi-threaded crawler approach whose results are updated using an event-driven approach that accounts for changes that may obsolete information acquired during the crawler approach. Transaction identifiers may be stored and potentially obsolete information preserved to facilitate providing views and rewind features.
