摘要： Aspects of this disclosure relate to protecting email data. For example, email protection rules can instruct an email server to route an email to an email protection module. The one or more email rules can identify a group of one or more email addresses. The email protection module can receive an email from the email server that has an email address of the group as an intended receipt. The email protection module can route the email to secondary storage and store the email in secondary storage to create a secondary copy of the email. The secondary copy can be stored inline to persistent memory of secondary storage, according to certain embodiments. Access to the backup copy of the email stored to the persistent memory can be controlled, for example, based on whether a user had permission to access to the email when the email was sent.

摘要： Rather than relying on pre-defined scheduling of secondary copy operations such as backup jobs, the illustrative opportunistic approach initiates secondary copy operations based on changing operational conditions in a storage management system. An adaptive backup readiness score is based on a number of backup-readiness operational factors. An illustrative enhanced data agent which is associated with the target database application (or other executable component) may monitor the operational factors and determine the backup readiness score based on weights assigned to the respective operational factors. The enhanced data agent may evaluate recent backup jobs to determine which of the operational factors that contributed to the backup readiness score may have been most relevant. Based on the most-relevant analysis, the enhanced data agent may adapt the weights assigned to the monitored operational factors, so that the backup readiness score may be more suitable and responsive to ongoing operational conditions in the system.

摘要： 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.

摘要： 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).

摘要： 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.

摘要： A method and system for providing unified access to data for multiple computing devices includes a system that associates multiple computing devices with a user of an information management system, assigns information management policies to data from the multiple computing devices within the information management system, and collects multiple data objects from the multiple computers. The system may generate a preview version of each collected data object, and provide at least one preview version of a collected data object to a computing device associated with the user. The system may also generate indexing information for each collected data object and distribute the indexing information with the preview version of the data object.

摘要： A information management system allows a user to search through a secondary copy of data, such as a back up, 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.
