Abstract: Certain embodiments described herein relate to an improved selective data backup system. In some embodiments, one or more components in an information management system can determine that a portion of the primary data scheduled for backup was previously backed up or is scheduled to be backed up as part of another backup operation. For example, a data agent performing a cluster-level backup operation for an entire cluster of storage servers may check whether any part of the primary data was previously backed up by a prior server-level backup operation for one of the storage servers in the cluster. If so, the data agent may skip, in the cluster-level backup operation, any portion of the primary data stored in the storage server previously backed up as part of the prior server-level backup operation.

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: 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 creating secondary copies of data (e.g., creating backup copies). The system can compute the score of the data (e.g., a computer file storing information) to be backed up, and determine whether the score satisfies one or more threshold criteria before backing up the data. In one example, a change in score indicates a change in the content of the data. The threshold criteria may be that the score be different from the score of the most recently backed up copy of the data.

Abstract: 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.

Abstract: 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.

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.

Abstract: According to certain aspects, a system may include a computing device configured to: intercept a request from a database application to read a portion of a database file, where a secondary copy of the database file resides on a secondary storage device(s) and is organized as a plurality of first blocks, wherein the request includes a database file offset(s) corresponding to the requested portion; and map the database file offset(s) to a subset of the first blocks that correspond to requested database object(s). The system may include a secondary storage controller computer(s) configured to: access a table that maps the plurality of first blocks to storage locations on the secondary storage device(s); using the table, locate and retrieve the subset of the first blocks on the secondary storage device(s); and forward the retrieved first blocks for storage in a primary storage device(s).

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).
