Abstract: A method and system described herein for classifying data of virtual machines in a heterogeneous computing comprising virtual machines and non-virtual machines. The system may access a secondary copy of data stored by a virtual machine, create metadata associated with that data, store the metadata in an index that comprises metadata associated with data stored on non-virtual machines, using a journal file, determine modified data objects within the data stored by the virtual machine, access or create metadata associated with modified data objects, and update the index accordingly.

Abstract: Systems and methods for performing file-level restore operations for block-level data volumes are described. In some embodiments, the systems and methods restore data from a block-level data volume contained in secondary storage by receiving a request to restore one or more files from the block-level data volume, mounting a virtual disk to the block-level data volume, accessing one or more mount paths established by the virtual disk between the data agent and the block-level data volume, and browsing data from one or more files within the block-level data volume via the established one or more mount paths provided by the virtual disk.

Abstract: Embodiments disclosed herein include systems and processes for replicating one or more user computing systems of an information management system at an external resource system to create a backup or fallback of the user computing systems. Replicating the user computing systems may include replicating data as well as the applications, operating systems and configuration of the user computing systems. This replicated or fallback user computing system may be implemented on a virtual machine at the external resource system. Thus, if a user computing system becomes inaccessible, a new user computing system can be generated based on the backup copy of the user computing system at the external resource system. Further, in some embodiments, the copy of the user computing system may be interacted with at the external resource system. Thus, certain embodiments disclosed herein can be used to transition an information management system to an external resource system.

Abstract: A method for automatically encrypting files is disclosed. In some cases, the method may be performed by computer hardware comprising one or more processors. The method can include detecting access to a first file, which may be stored in a primary storage system. Further, the method can include determining whether the access comprises a write access. In response to determining that the access comprises a write access, the method can include accessing file metadata associated with the first file and accessing a set of encryption rules. In addition, the method can include determining whether the file metadata satisfies the set of encryption rules. In response to determining that the file metadata satisfies the set of encryption rules, the method can include encrypting the first file to obtain a first encrypted file and modifying an extension of the first encrypted file to include an encryption extension.

Abstract: Software, firmware, and systems are described herein that migrate functionality of a source physical computing device to a destination virtual machine. A non-production copy of data associated with a source physical computing device is created. A configuration of the source physical computing device is determined. A configuration for a destination virtual machine is determined based at least in part on the configuration of the source physical computing device. The destination virtual machine is provided access to data and metadata associated with the source physical computing device using the non-production copy of data associated with the source physical computing device.

Abstract: According to certain aspects, a system may include a data agent configured to: process a database file residing on a primary storage device(s) to identify a subset of data in the database file for archiving, the database file generated by a database application; and extract the subset of the data from the database file and store the subset of the data in an archive file on the primary storage device(s) as a plurality of blocks having a common size; and at least one secondary storage controller computer configured to, as part of a secondary copy operation in which the archive file is copied to a secondary storage device(s): copy the plurality of blocks to the secondary storage devices to create a secondary copy of the archive file; and create a table that provides a mapping between the copied plurality of blocks and corresponding locations in the secondary storage device(s).

Abstract: Software, firmware, and systems are described herein that permit an organization to dock previously-utilized, limited-feature data management modules with a full-featured data management system. By docking limited-feature data management modules to a full-featured data management system, metadata and data from the various limited-feature data management modules can be integrated and utilized more efficiently and effectively. Moreover, additional data management features can be provided to users after a more seamless transition.

Abstract: Virtual machine (VM) proliferation may be reduced by determining the availability of existing VMs to perform a task. Tasks may be assigned to existing VMs instead of creating a new VM to perform the task. Furthermore, a coordinator may determine a grouping of VMs or VM hosts based on one or more factors associated with the VMs or the VM hosts, such as VM type or geographical location of the VM hosts. The coordinator may also assign one or more Virtual Server Agents (VSAs) to facilitate managing the group of VM hosts. In some embodiments, the coordinators may facilitate load balancing of VSAs during operation, such as during a backup operation, a restore operation, or any other operation between a primary storage system and a secondary storage system.

Abstract: Hypervisor-independent block-level live browse is used for directly accessing backed up virtual machine (VM) data. Hypervisor-free file-level recovery (block-level pseudo-mount) from backed up VMs also is disclosed. Backed up virtual machine (“VM”) data can be browsed without needing or using a hypervisor. Individual backed up VM files can be requested and restored to anywhere without a hypervisor and without the need to restore the rest of the backed up virtual disk. Hypervisor-agnostic VM backups can be browsed and recovered without a hypervisor and from anywhere, and individual backed up VM files can be restored to anywhere, e.g., to a different VM platform, to a non-VM environment, without restoring an entire virtual disk, and without a recovery data agent at the destination.

Abstract: A system stores a snapshot and an associated data structure or index to storage media to create a secondary copy of a volume of data. In some cases, the associated index includes application specific data about a file system or other application that created the data to identify the location of the data. The associated index may include three entries, and may be used to facilitate the recovery of data via the snapshot. The snapshot may be used by ancillary applications to perform various functions, such as content indexing, data classification, deduplication, e-discovery, and other functions.
