    Abstract: Systems and methods for managing electronic data are disclosed. Various data management operations can be performed based on a metabase formed from metadata. Such metadata can be identified from an index of data interactions generated by a journaling module, and obtained from their associated data objects stored in one or more storage devices. In various embodiments, such processing of the index and storing of the metadata can facilitate, for example, enhanced data management operations, enhanced data identification operations, enhanced storage operations, data classification for organizing and storing the metadata, cataloging of metadata for the stored metadata, and/or user interfaces for managing data. In various embodiments, the metabase can be configured in different ways. For example, the metabase can be stored separately from the data objects so as to allow obtaining of information about the data objects without accessing the data objects or a data structure used by a file system.

    Abstract: A method and system for identifying changes to a data set, such as data within a mailbox, and performing actions based on the identified changes is discussed. In some examples, the system receives an indication of a change to a mailbox, creates a change journal entry for the change, and identifies data to be copied via the change journal entry. In some examples, the system leverages the change journal to associate messages with changes to a mailbox.

    Abstract: Systems and methods for replicating database data in a dirty shutdown state and generating copies of the replicated data in a clean shutdown state. For example, systems can include a tracking module (e.g., a filter driver) that monitors transactions from a database application to a source database stored on a source storage device to generate log entries having at least one marker indicating a known good state of the application. The systems further include a computer coupled to a target storage device comprising a target database and log files. The computer processes the transactions, based on the log entries, to replicate data to a target database on the target storage device; performs a first snapshot on data stored in the target database existing in a dirty shutdown state; replays into the target database data stored in the log files to put the target database in a clean shutdown state; copies the target database in the clean shutdown state; and reverts the target database back to the dirty shutdown state in which the target database existed at the time of the first snapshot.
