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: A system according to certain aspects may include a client computing device including: a database application configured to output a database file in a primary storage device(s), the database application outputting the database file as a series of application-level blocks; and a data agent configured to divide the database file into a plurality of first blocks having a first granularity larger than a second granularity of the application-level blocks such that each of the first blocks spans a plurality of the application-level blocks. The system may include a secondary storage controller computer(s) configured to: in response to instructions to create a secondary copy of the database file: copy the plurality of first blocks to a secondary storage device(s) to create a secondary copy of the database file; and create a table that provides a mapping between the copied plurality of first blocks and corresponding locations on the secondary storage device(s).

Abstract: Systems and methods for providing data storage operations, such as archiving and/or backing up of data, for mail servers, such as Exchange servers, via a Simple Mail Transfer Protocol (SMTP) interface are described. For example, the systems and methods may provide an SMTP server between one or more Exchange servers and a media agent, which is configured to performing secondary copy operations, in order to quickly and/or efficiently generate archive or other secondary copies of various mailboxes within the mail server before or during the transfer of mail data to the media agent for data storage operations.

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.
