Abstract: The present inventors devised a holistic approach for protecting serverless applications in single-cloud, multi-zone, multi-cloud, and/or non-cloud data center computing environments. An illustrative data storage management system discovers application assets, relationships, and interoperability dependencies and creates an “application entity” that references the various assets. Protection preferences apply to the application entity as a whole. An orchestration function in the system coordinates storage management operations (e.g., backup, replication, live synchronization, etc.) in a suitable order of operations gleaned from asset dependencies, if any. A set of copies of the application's discovered assets are generated in coordinated fashion and represent a point-in-time copy of the application. The point-in-time copy can be restored and/or migrated to other computing services by the data storage management system. The orchestration function coordinates restore and migration operations, including any cloud-to-cloud or cloud-to/from-non-cloud conversions that might be necessary to activate the application in a different computing environment.

Abstract: A system for performing continuous transaction log backups with minimal resource usage of the client computing devices that are processing the transactions is disclosed. The system detects at least one input/output (I/O) activity at a client computing device. The I/O activity can be associated with at least one database operation performed via the client computing device. The system then executes one or more native commands to backup transactions log data associated with the detected I/O activity to a virtualized location. Backing-up the transactions log data comprises dynamically identifying a mount path location corresponding to the virtualized location, and transferring the transactions log data to the dynamically identified mount path using the one or more native commands. The system can then perform data processing operations (for example, data chunking and deduplicating) on the transactions log data after it is received at the dynamically identified mount path location.

Abstract: An information management system allows a user to search through a secondary copy of data, such as a backup, archive, or snapshot without first retrieving the secondary copy of data. Instead, the system constructs lightweight data that can be displayed to a user as a representation of the search results. Lightweight data may include metadata or other information that identifies data included in the secondary copy of data. The lightweight data may be perceived as being the secondary copy of data and allow a user to browse through search results. Once the user identifies a search result that is of interest, information in the lightweight data can be used to retrieve the secondary copy of data. Because lightweight data may have a smaller file size than the file size of the secondary copy of data, the latency of performing a search may be reduced.

Abstract: Systems and methods are disclosed for cross-system user-level management of data objects stored in one or more information management systems, and for user-level management of data storage quotas in information management systems, including data objects in secondary storage. An illustrative quota manager is associated with one or more information management systems. The quota manager comprises a quota value representing the maximum amount of data storage allowed for a given end-user's primary and secondary data in the one or more information management systems. The quota manager determines whether data associated with the end-user has exceeded the storage quota, and if so, prompts the end-user to select data for deletion, the deletion to be implemented globally, across the primary and secondary storage subsystems of the respective one or more information management systems. Meanwhile, so long as the quota is exceeded, the quota manager instructs storage managers to block backups of end-user's data.

Abstract: Systems and methods for providing and/or facilitating live browsing of granular mail or mailbox data, such as data stored within Exchange mailboxes, are described. For example, the systems and methods may provide mechanisms for browsing and/or restoring granular data (e.g., email data) from an Exchange database backup copy (or other secondary copy), without having to restore the entire database from the backup copy.

Abstract: According to certain aspects, a system may include a data agent configured to: process a database file residing on a primary storage device(s) to identify a subset of data in the database file for archiving, the database file generated by a database application; and extract the subset of the data from the database file and store the subset of the data in an archive file on the primary storage device(s) as a plurality of blocks having a common size; and at least one secondary storage controller computer configured to, as part of a secondary copy operation in which the archive file is copied to a secondary storage device(s): copy the plurality of blocks to the secondary storage devices to create a secondary copy of the archive file; and create a table that provides a mapping between the copied plurality of blocks and corresponding locations in the secondary storage device(s).

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: A system according to certain aspects improves the process of sending emails containing attachments. The system can detect a request to send an email containing attachments to one or more recipients, create a copy of the attachments on a network storage device, replace the attachments contained in the email with links to the copies of the attachments, and send the email containing the links to the one or more recipients.

Abstract: A method and system for providing on-demand updating of metadata information associated with clinical image data files is disclosed. The system allows for extracting, on the fly, additional metadata fields from clinical image data files and re-indexing the metadata to include the additional fields so that an end-user can perform operations (e.g., searching, browsing, etc.) based on the newly indexed fields. The metadata fields may be defined in a configurable schema file (e.g., XML, YML, etc.). The system can gain efficiencies by, for example, reading only a subset of the DICOM file (e.g., reading only the first few kilobytes that contain the header), scanning only a subset of source data folders, etc.

Abstract: A system for providing user access to electronic mail includes an email client and an email server. The email client receives and communicates a user interaction with an email message The email server that receives the communication, determines whether the email message stored in a live database or in a backup storage. Upon determination that the email message is stored in a backup storage, the email server performs a message exchange with a backup storage system to perform the user-requested action.
