Abstract: Described is a system for synchronizing expiration times for incremental backup data stored on a cloud-based object storage. More particularly, the system may provide a layer of intelligence when updating the expiration times associated with backup data to ensure that a full recovery of the client data to a point-in-time of any incremental backup may be performed. To provide such a capability, the system may maintain specialized metadata identifying expiration times for objects and a list of objects required to perform a full recovery to a point-in-time for each of the performed backups (e.g. full or incremental). The system may access this metadata to identify which objects stored by a previous backup are still referenced by a subsequent backup. Based on the identified objects, the system may synchronize object expiration times to ensure objects are not prematurely deleted from the object storage.

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 backup storage for managing backups of clients includes persistent storage and a backup analyzer. The persistent storage includes the backups, protection policies, and an early deletion schedule. The backup analyzer obtains a request to analyze a protection policy of the protection policies; in response to obtaining the request: obtains backup data information associated with the protection policy; makes a determination, based on the backup data information and the protection policy, that a portion of the backups associated with the protection policies overprotect a client of the clients associated with the protection policy; and modifies the early deletion schedule based on the determination to obtain a modified early deletion schedule.

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 manager for managing generation of backups for clients includes persistent storage and a backup manager. The persistent storage stored protection policies associated with the clients and native backup functionality information associated with the clients. The backup manager programmed obtains a portion of the native backup functionality information from a client of the clients; obtains at least one protection policy of the protection policies that is associated with the client; makes a determination that the at least one protection policy and the portion of the native backup functionality information are unique; in response to the determination: generates modifier data based on: the portion of the native backup functionality information and the at least one protection policy; and generates a backup for the client using a modifier associated with the modifier data.

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: Systems and methods for protecting and identifying virtual machines that have the same name in a multi-tenant distributed environment are provided. When backing up a virtual machine, a unique identifier of the virtual machine is incorporated into the name of the virtual machine's save set. This allows a backup administrator to distinguish between virtual machines that have the same name. This improves the ability to perform restore operations by enabling virtual machines that have the same name to be distinguished.

Abstract: Techniques for virtual proxy based backup of virtual machines in a cluster environment are disclosed. In some embodiments, each of a subset of virtual machines hosted by physical nodes in a cluster environment is configured as a virtual proxy dedicated to backup operations. During backup, data rollover of each virtual machine in the cluster environment that is subjected to backup is performed using a virtual proxy.

Abstract: Described is a system (and method) for specialized data management when performing incremental backups to a cloud-based object storage. When backing up client data, the server may utilize incremental backups to conserve the amount of storage space required on the object storage. However, the server may implement a configuration that enables full reconstruction of the client data at the time of recovery. To provide such capabilities, the server may leverage a specialized metadata database. The metadata database may be an embedded database maintained by the server. The server may leverage the metadata database to provide further storage efficiencies by storing certain incremental backup data exclusively within the metadata database. Accordingly, the server may implement a data management configuration as part of a backup service that conserves storage usage, and as a result, storage costs when using on a third-party cloud-based object storage.
