  • Patent number: 10949240
    Abstract: An illustrative “Live Synchronization” feature in a data storage management system can reduce the downtime that arises in failover situations. The illustrative Live Sync embodiment uses backup data to create and maintain a ready (or “warm”) virtualized computing platform comprising one or more virtual machines (“VMs”) that are configured and ready to be activated and take over data processing from another data processing platform operating in the production environment. The “warm” computing platform awaits activation as a failover solution for the production system(s) and can be co-located at the production data center, or configured at a remote or disaster recovery site, which in some embodiments is configured “in the cloud.” Both local and remote illustrative embodiments are discussed herein. An “incremental forever” approach can be combined with deduplication and synthetic full backups to speed up data transfer and update the disaster recovery sites.

  • Publication number: 20210034473
    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.

  • Patent number: 10896053
    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.

  • Patent number: 10896104
    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.

  • Publication number: 20210011754
    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.

  • Publication number: 20200341945
    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.
