Abstract: Systems, methods, and computer-readable media can present improved data backup of data servers, including Microsoft Exchange servers. Embodiments can provide backup of a data server using a backup application, where the backup application can send a request to the data server for data to backup and receive a first set of backup data from the data server. The backup application can also send a request to the data server for backup data criteria and receive backup data criteria from the data server. The backup application may apply the backup data criteria to the first set of data to create a second set of backup data that is new, non-duplicated data sending the second set of backup data to a storage device, thus saving storage space, backup time, and network bandwidth.

Abstract: Techniques to protect against data loss are disclosed. In various embodiments, an amount of data that has changed since a last backup of at least a defined subset of a save set is determined. The determined amount of changed data is compared to a corresponding threshold. A backup is performed based at least part on a determination that the determined amount of changed data equals or exceeds the threshold.

Abstract: Described is a system for cloud-based processing of backup data for storage onto various types of object storage systems. A specialized cloud-based component (e.g. proxy server) may act as an intermediary when backing up data from a client system to an object storage. For example, the cloud-based component may be provided as part of backup service that operates in conjunction with a client system. Accordingly, the system may allow different clients of a backup service to efficiently and seamlessly interact with the different third-party object storage providers via a single cloud-based component. To provide such object-storage-agnostic functionality, the cloud-based component may include a function library that includes object-storage-specific functions. For example, the cloud-based component may invoke a specific set of operations that interact with a storage API provided by a particular object storage provider.

Abstract: Described is a system for rule-based re-tiering of backup data stored on a cloud-based object storage. More specifically, the system may re-tier objects based on one or more storage rules such that the system retains the ability to efficiently perform a full restore of backup data even when incremental backups are performed to a cloud-based object storage. To provide such a capability, the system may maintain a specialized metadata database that stores information indicating the backup time for each backup, and a list of objects required to perform a full restore to each of the backup times. Accordingly, when initiating a re-tiering based on one or more storage rules, the system may intelligently select candidate objects for re-tiering by leveraging the metadata database to ensure that objects that may still need to be referenced are not unnecessarily moved to a lower storage tier.

Abstract: A system for providing backup services for limited-access user data includes persistent storage for storing a user data visualization enhanced user data backup and a manager. The manager identifies a backup generation event for limited-access user data based on a protection policy; in response to identifying the backup generation event, obtains fragmented user data from an application that gates access to the limited-access user data; obtains organizational metadata associated with the fragmented user data from the application; makes a determination that the fragmented user data is associated with a user data visualization; in response to making the determination, obtains user data visualization metadata associated with the fragmented user data from the application; and generates the user data enhanced user data backup using the organizational metadata, the user data visualization metadata, and the fragmented user data.

Abstract: A system for providing data protection services for user data generated by an application, includes persistent storage for storing user data backups and a manager. The manager is programmed to identify a backup generation event for user data based on a protection policy, in response to identifying the backup generation event, obtain user data associated with the backup generation event from the application, select a calendar of calendars included in the user data, obtain user metadata associated with the calendar, and generate a user data backup using the user data and the user metadata, in which the user data backup comprises calendar events of the calendar and portions of the user metadata associated with the calendar events.

Abstract: A system for providing data protection services for user data generated by an application includes persistent storage that includes an archive storage and a backup storage. The system also includes a manager. The manager is programmed to generate data chunks using user data, generate backup object metadata associated with the data chunks; obtain previously generated backup object metadata associated with the user data using an archive value, make a first determination that at least one data chunk of the data chunks is to be archived using the backup object metadata and the previously generated backup object metadata, and, in response to the first determination: store the at least one data chunk in the archive storage as a portion of a user data backup, and store remaining data chunks of the data chunks in the backup storage as the remaining portion of the user data backup.

Abstract: A system including persistent storage for storing an object repository and a user data backup. The system also includes a manager that obtains fragmented user data associated with an object that is potentially duplicative of an object stored in the object repository; makes a determination that the object is duplicative based on a copy of the object stored in the object repository; in response to making the determination, adds the fragmented user data to a user data backup without adding the object to the backup; associates the fragmented user data in the user data backup with the copy of the object stored in the object repository; and stores the user data backup in the persistent storage.
