Abstract: Embodiments of the invention relate to methods and systems that improve the operation of one or more computing devices by allowing backups and restorations to be performed on files and folders that are normally unavailable for normal restoration. By utilizing the backup's meta-data, a backup agent can receive an indication that a file or folder is not available and take appropriate actions so that the files and folders that are normally not available can be properly restored. Making it possible to efficiently perform a backup of a file-system that can be restored even when files and/or folders are normally unavailable to be restored normally.

Abstract: Embodiments of the invention relate to methods and systems for backing up user defined logical assets. In accordance with one or more embodiments, a user may define a logical asset type prior to a backup being performed. The user may define the logical asset type based on any rules, filters, or attributes of files and/or folders stored in a file system. Once the user has defined the asset type, the system may utilize file-system meta-data to quickly ascertain which files and folders meet the definition of the logical asset type, allowing for the backup of the user defined asset to be performed with minimal additional workload by the production hosts, clients, backup agents, and other associated components of the system.

Abstract: A method for performing data backup includes: receiving a backup request specifying a file where the file is stored in a shared storage. Additionally, in response to the backup request: retrieving, by a primary data node, properties of the file; determining, by the primary data node, resource availability for plurality of secondary data nodes where the primary data node and the plurality of secondary data nodes is operatively connected to the shared storage and a backup storage; logically dividing, by the primary data node, the file into a plurality of segments using at least the properties of the file; and coordinating, by the primary data node, the backup of the file using the plurality of segments and the resource availability of the plurality of secondary data nodes.

Abstract: A backup manager for providing backup services includes persistent storage and a backup orchestrator. The persistent storage includes protection policies. The backup orchestrator generates a backup for a client based on the protection policies; obtains system metadata from the client; generates a backup map for the backup based on the system metadata; generates a backup hierarchy for the backup based on the backup map; and stores the backup and at least one selected from a group consisting of the backup hierarchy and the backup map.

Abstract: Techniques described herein relate to a method for generating backups of virtual machines. The method may include, in response to identifying a backup generation event associated with virtual machines: obtaining, by a backup agent, virtual machine metadata associated with the virtual machines; identifying groups of virtual machines based on the virtual machine metadata; provisioning resources to generate backups of the virtual machines based on the groups of virtual machines; and generating a backup of the virtual machines based on the groups of virtual machines using the provisioned resources associated with the groups of virtual machines.

Abstract: Backup operations may save a full backup and subsequent checkpoints. Systems and methods for handling backup and restore operations when checkpoints are deleted. Checkpoints can be merged during a restore operation to account for deleted checkpoints. Also, the backup can continue to leverage existing backups even though checkpoints have been deleted.

Abstract: A production host for hosting applications includes a persistent storage and a production agent. The persistent storage stores application data of the applications. The production agent obtains a backup analysis request for an application executing on the production host; in response to obtaining the backup analysis request: obtains an identity of the application; identifies backups in a backup storage, wherein the identified backups are associated with the identity of the application; performs a backup policy compliance analysis of the identified backups to generate a backup protection map for the application.

Abstract: A method and system for backup processes that includes identifying a target volume and identifying a number of available threads to back up the target volume. The elements in the target volume are distributed among the available threads based on a currently pending size of data in the threads. The elements are stored from each thread into a backup container, and merged from each of the backup containers into a backup volume.

Abstract: A backup manager for providing backup services includes persistent storage and a backup orchestrator. The persistent storage includes protection policies. The backup orchestrator generates a backup for a client based on the protection policies. The backup orchestrator generates an index for the backup. The index specifies a sensitivity level of each portion of the backup. The backup orchestrator stores portions of the backup in regions of a container that correspond to the sensitivity level of the respective portion of the backup. The backup orchestrator stores the container in backup storage.
