Abstract: A system according to certain aspects improves the process of restoring database objects and converting those objects into another database file format. According to certain aspects, a database file is backed up in a block-level fashion. Instead of restoring the entire backup file, the information management system may restore a particular database object from a backup database file that is stored as multiple blocks or other granular units. Then, the information management system can extract the desired data from the restored block(s). By using block-level mapping and storage techniques described herein, the system can restore a database object in a backup database file without restoring the entire backup database file, thereby speeding up restore operations and reducing consumption of storage and processing resources. In addition, the information management system can convert the blocks, using a staging memory, to another database file format as desired.

Abstract: An improved content indexing (CI) system is disclosed herein. For example, the improved CI system may include a distributed architecture of client computing devices, media agents, a single backup and CI database, and a pool of servers. After a file backup occurs, the backup and CI database may include file metadata indices and other information associated with backed up files. Servers in the pool of servers may, in parallel, query the backup and CI database for a list of files assigned to the respective server that have not been content indexed. The servers may then request a media agent to restore the assigned files from secondary storage and provide the restored files to the servers. The servers may then content index the received restored files. Once the content indexing is complete, the servers can send the content index information to the backup and CI database for storage.

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: Virtualization sprawl can lead to virtual machines with no designated periodic backup. If the data associated with these unprotected virtual machines is not backed up, it cannot be restored if needed, leading to system failures. A data storage system identifies and protects the unprotected virtual machines. For instance, the system compares a list of virtual machines with a list of computing devices having a designated backup policy in the data storage system and determines which of the virtual machines are unprotected. The system further automatically categorizes the unprotected virtual machines, identifies those unprotected virtual machines that remain uncategorized, and applies a default backup policy to the uncategorized and unprotected virtual machines to provide protected virtual machines.

Abstract: An illustrative “VM heartbeat monitoring network” of heartbeat monitor nodes monitors target VMs in a data storage management system. Accordingly, target VMs are distributed and re-distributed among illustrative worker monitor nodes according to preferences in an illustrative VM distribution logic. Worker heartbeat monitor nodes use an illustrative ping monitoring logic to transmit special-purpose heartbeat packets to respective target VMs and to track ping responses. If a target VM is ultimately confirmed failed by its worker monitor node, an illustrative master monitor node triggers an enhanced storage manager to initiate failover for the failed VM. The enhanced storage manager communicates with the heartbeat monitor nodes and also manages VM failovers and other storage management operations in the system. Special features for cloud-to-cloud failover scenarios enable a VM in a first region of a public cloud to fail over to a second region.

Abstract: According to certain aspects, a method can include creating a backup copy of data associated with a virtual machine (VM) on one or more secondary storage devices, wherein the backup copy includes corresponding secondary copies of a plurality of files associated with the VM; analyzing metadata associated with the secondary copies to determine which of the plurality files are eligible to be removed from the primary storage device; in response determining that one or more files are eligible to be removed from the primary storage device, for respective file of the one or more files: determining whether the respective file has been changed since a first time at which the backup copy of the data associated with the VM was created; in response to determining that the respective file has not changed since the first time, removing the respective file; and adding a file placeholder for the removed file.

Abstract: A data storage system protects data identified for deletion which has been created or modified between scheduled data backups. For instance, the system monitors data operations and when the data operation is a delete, the system determines whether the data identified for deletion has been protected by a backup operation. Data that has not been backed up, such as newly created data, is copied to temporary storage before deletion. When the data has been protected, the system determines whether the data has been modified after the backup operation. Data modified after the backup operation is copied to temporary storage before deletion.

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: Systems and methods integrate disparate backup devices with a unified interface. In certain examples, a management console manages data from various backup devices, while retaining such data in its native format. The management console can display a hierarchical view of the client devices and/or their data and can further provide utilities for processing the various data formats. A data structure including fields for storing both metadata common to the client device data and value-added metadata can be used to mine or process the data of the disparate client devices. The unified single platform and interface reduces the need for multiple data management products and/or customized data utilities for each individual client device and provides a single pane of glass view into data management operations. Integrating the various types of storage formats and media allows a user to retain existing storage infrastructures and further facilitates scaling to meet long-term management needs.
