  • Patent number: 11599511
    Abstract: In one example, a method includes obtaining cluster and machine configuration information, sending a restore request for one or more machines, and loading a backup of a virtual machine, the backup having been created by a federated backup process involving the physical proxy node, and the virtual machine includes data that resides on a virtual federated database that is an element of a cluster environment and to which respective databases of each of a plurality of nodes of the cluster environment are mapped. Next, the virtual machine is taken offline after the backup of the virtual machine has been loaded, and after the virtual machine has been taken offline, the virtual machine is removed from the node where it resides. The backup of the virtual machine is then restored, and the restored virtual machine brought online, after which the restored virtual machine is enabled as a cluster-wide virtual machine.

  • Publication number: 20230065486
    Abstract: Described is a system (and method) for leveraging data previously transferred to a cloud-based object storage as part of a failed backup when performing a subsequent backup operation. The system may leverage the native configuration of an object storage that may retain certain data even when a backup operation is classified as a failed operation. To provide such capabilities, the system may store specialized metadata that tracks which backups have failed and metadata indicating which backup data has not been committed. Accordingly, upon a subsequent backup operation, the system may expediently refer to the stored metadata to identify retained backup data that may be reused for the subsequent backup. As a result, the system may improve the efficiency of a backup procedure by reducing the amount of data required to be transferred from the backup source.

  • Patent number: 11593497
    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.

  • Publication number: 20220398170
    Abstract: A method and system for leveraging file-based backups to facilitate bare-metal recovery (BMR) and/or system-state recovery (SSR) operations. In leading to a BMR operation (which may include, but is not limited to, data protected under a SSR operation), logical groupings of data, each including multiple files and/or directories that span across one or more file-systems, may be written to backup media to comply with data backup, archiving, and/or disaster recovery strategies. Backing up said logical groupings of data relies on block-based backup technologies, which upon requiring a subset of a given logical grouping of data to be restored, makes the restoration process impossible to fulfill since determining which blocks of data belong to which files and/or directories are not tracked. Accordingly, the disclosed method and system propose an intelligent scheme through which file-based backup technology may be employed to enable BMR and/or SSR from any single BMR-compliant backup copy.

  • Publication number: 20220398162
    Abstract: A method for managing file based backups (FBBs) includes obtaining, by a backup agent, a FBB generation request for a file system at a point in time, in response to the FBB generation request: identifying a target backup storage system in which to store the FBB, identifying a target exposed application programming interface (API) associated with the target backup storage system, generating a FBB corresponding to the FBB generation request, wherein the FBB comprises a FBB metadata file, wherein the FBB is in a common data streaming format (CDSF), generating an API command based on the FBB and the target exposed API, and initiating storage of the FBB in the target backup storage system using the API command.

  • Publication number: 20220382644
    Abstract: Described is a system (and method) for size-based organization of backup files within an object storage for efficient object re-tiering. The system may perform a specialized process to re-tier objects stored within an object storage by organizing backup files into individual or shared objects based on a backup file size. Accordingly, the system may initiate a re-tiering of objects immediately after performing an incremental backup to improve storage efficiency while at the same time retaining the ability to synthetically perform a full restore.

  • Publication number: 20220382652
    Abstract: Described is a system (and method) for efficient access-based reallocation of backup data stored within an object storage. The system may implement various specialized procedures to efficiently store and manage backup data within the object storage. These procedures may include packing backup data into objects to improve data operation efficiency. The system may also conserve storage space on the object storage by performing an analysis to reallocate backup data as necessary. For example, data may be stored in objects in an immutable manner, and thus, the system may efficiently reallocate data to new objects based on data access patterns. For example, the system may determine an access pattern associated with live data remaining within the first object satisfies a condition, and in response, reallocated the live data to a new object.

  • Publication number: 20220382639
    Abstract: Described is a system for managing the expiration of objects storing incremental backup data by leveraging specialized metadata. The system may provide a layer of intelligence when freeing up storage space on an object storage to ensure that a full recovery of client backup data may be performed when storing incremental backup data. The system may maintain metadata indicating the latest and/or earliest backups that reference particular objects. The system may then leverage this information to mark particular objects for removal (e.g. deletion or re-tiering). For example, the system may access the metadata to identify which objects stored by a previous (e.g. expired) backup are still referenced by a subsequent (e.g. non-expired) backup. As a result, the system may ensure that objects are not removed prematurely and that a full recovery of the client data to a point-in-time of any incremental backup may be performed.

  • Publication number: 20220382646
    Abstract: Described is a system (and method) for application-based packing for storing backup data within an object storage. More particularly, the system may efficiently pack backup files into objects having a specialized size by accounting for the source and size of the backup file. For example, the system may determine whether backup files associated with a particular application may be stored within individual objects or packed together within a shared object. Accordingly, by accounting for such criteria the system may perform an intelligent allocation of backup data within a cloud-based object storage. The system may be implemented as part of an incremental backup infrastructure. Accordingly, when allocating the backup files amongst objects, the system may also store specialized metadata to preserve the ability to perform a reconstruction of data (e.g. synthetically) as if a full backup was performed.
