Abstract: Described is a system (and method) for providing multiple types of granular delete operations for a cloud-based object storage. The system may include a server that acts as an intermediary between a client device and an object storage that stores client data. The server may allow a client to perform a hard delete (or permanent) delete and a soft delete. The server may perform a specialized processing to synthetically create the soft delete feature using a permanent object delete operation provided by the object storage. The specialized processing may include manipulating retention periods associated with objects depending on whether the object is subject to a hard delete or a soft delete. As a result, the server may provide the ability for clients to perform a soft delete at an object level using existing storage level APIs that do not directly support such a feature.

Abstract: A manager for providing services to clients includes persistent storage and an orchestration manager. The persistent storage includes protection policies. The orchestration manager obtains a backup from a client of the clients based on a protection policy of the protection policies; makes a determination that an application catalog associated with the client is not stored in backup storages; in response to making the determination: obtains the application catalog from the client; stores the application catalog in the backup storages; and stores the obtained backup in the backup storages.

Abstract: Described is a system (and method) for cross application granular restore of email attachments backed up to a cloud-based object storage. More particularly, the system may allow various non-email applications to directly restore an email attachment of a backed-up email without requiring restoration of the email itself. The attachment may be a file, item (e.g., contact, event, message, etc.), or another type of attachment such as a link to a file or an item. To provide such a capability, the system may decouple the attachment from an email when performing a backup to an object storage. The system may also store specialized metadata that may be leveraged when performing an efficient restore of the attachment.

Abstract: Described is a system for cloud-based scheduling of data operations to an object storage. The system may include a server that acts as an intermediary between a client device and an object storage that stores client data. Requests by the client device to manage data on the object storage may be routed through the server. In response, the server may execute corresponding data operations directly on the object storage. The server may manage bandwidth limits for operation requests to an object storage by maintaining a specialized operation pool. The operation pool may be configured to manage operation-specific queues, and these operation-specific queues may include sub-operations (or threads) that are executed on the object storage. Sub-operations of various types of operations may be initiated for concurrent execution on the object storage based on scheduling information derived from the operation pool.

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 fragmented user data and a manager. The manager identifies a backup generation event for the limited-access user data based on a protection policy; in response to identifying the backup generation event, obtains the fragmented user data from an application that gates access to the limited-access user data; identifies, based on the fragmented user data, organizational metadata for generating a user data backup; obtains the identified organizational metadata from the application; and generates the user data backup using the organizational metadata and the fragmented user data.

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.

Abstract: A system for providing backup services for limited-access user data includes persistent storage and a manager. The manager identifies a backup generation event for the limited-access user data based on a protection policy; in response to identifying the backup generation event, performs, using an application that gates access to the limited-access user data, a change analysis of the limited-access user data to identify a portion of the limited-access user data that is potentially in a backed-up state; obtains, using the application, metadata associated with the portion indicative of whether sub-portions of the portion are in the backed-up state; identify, using the metadata, at least one of the sub-portions that is not in the backed-up state; and generates the user data backup using the at least one of the sub-portions.

Abstract: A system for providing backup services for limited-access user data includes persistent storage for storing a conversation specific 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 conversation; in response to making the determination, obtains conversation metadata associated with the fragmented user data from the application; and generates the conversation specific user data backup using the organizational metadata, conversation metadata, and the fragmented user data.

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.

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: 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: A cluster includes cluster shared volumes and nodes. A subset of the nodes are designated as being backup proxy nodes responsible for backing up the cluster shared volumes. The cluster shared volumes are divided into groups, each group having a number of cluster shared volumes that is less than a total number of cluster shared volumes in the cluster. Generation is initiated for a particular snapshot for a number of cluster shared volumes belonging to a particular group. The backup proxy nodes backup data from the particular cluster shared volumes belong to the particular group using the particular snapshot. After the backup, the steps initiating snapshot generation and backing up are repeated until each group of cluster shared volumes has been backed up.

Abstract: Embodiments are directed to a method of backing up virtual machines coupled to a backup server in a large-scale data storage system, by installing a single instance of a backup management program on the backup server; pushing, by the backup management program, a backup agent to each virtual machine; detecting, through the backup agent, all applications running on a respective virtual machine; taking a snapshot of each application after freezing the applications and prior to thawing the applications, by the backup agent; and saving the snapshot of the each applications on a storage medium. The pushing step comprises creating a shared folder and exposing the shared folder to all the virtual machines for remote invocation by the backup program.
