Abstract: Systems and methods for discovering applications. An application may be discovered by determining a topology of the application in a containerized platform. Discovering the topology may include determining the components of the application and then determining relationships between the components. The relationships may include whether a component (e.g., a microservice) is user facing and may be based on traffic patterns between the components. The components or microservices may be prioritized or ranked based on the topology. The topology can be used when performing a data protection operation such as a restore operation.

Abstract: A node for use in a data management system includes a persistent storage and a data protection agent. The persistent storage stores data. The data protection agent makes an identification of a data protection strategy change event for the data; in response to the identification: makes a determination that the data protection strategy change event is a scale down event; in response to the determination: identifies a number of replicas of the data in other nodes that are in a predetermined state; makes a second determination that the number of the replicas of the data in the other nodes that are in the predetermined state exceeds a threshold specified by a data protection policy associated with the data protection strategy change event; and reduces the number of replicas that exceed the threshold to be less than the threshold in response to the second determination.

Abstract: A method and system for performance-driven load shifting. Specifically, the method and system disclosed herein entail transferring user program workloads, for processing, between local computing resources available on a client device and cloud computing resources available on an offload domain based on the assessed performance score of the client device at any given point in time. Seamless load shifting is further guaranteed due substantively to the employment of a mobile network facilitating communications between the client device and the offload domain.

Abstract: One example method includes receiving input concerning a boot order sequence, where the input includes VM metadata, entering a training phase which includes generating a boot sequence rule based on the input, using the boot sequence rule to generate a proposed boot sequence, performing the proposed boot sequence, and gathering information concerning performance of the proposed boot sequence. The gathered information can be used as a basis to generate a modified boot sequence.

Abstract: A method for data defragmentation is disclosed, including: selecting a file that is stored in a content-addressable storage system, the file including a plurality of blocks, and the storage system including a plurality of deduplication chunks; arranging the plurality of blocks in block groups, each block group including a set of consecutive blocks having a combined size that matches a deduplication chunk size of the storage system; aligning each block group with a different one of the plurality of deduplication chunks of the storage system, such that the blocks in each block group are stored in the storage system in an order that is based on the order in which the blocks are positioned within the file.

Abstract: A storage system comprises an object store, which comprises a plurality of metadata objects, a plurality of change objects, and a plurality of data objects associated with data stored in at least one logical unit of a production site, and a replication site configured to generate a requested point in time (PIT) based at least in part on the plurality of data objects, by: dividing the plurality of metadata objects into a plurality of respective portions of metadata objects; mapping each respective portion of metadata objects to a respective one of a plurality of reducer nodes; performing map reduce operations on the respective portion of metadata objects, at each respective one of the plurality of reducer nodes, to apply the most recent list of changes that occurred to each offset before the first requested PIT; and merging together the list of changes from each reducer node into the requested PIT.

Abstract: A method includes designating one or more particular portions of a storage volume of a storage system for inclusion in a sub-volume snapshot. The method further includes generating the sub-volume snapshot as a point-in-time copy that includes the one or more designated portions of the storage volume and excludes one or more non-designated portions of the storage volume. The method is performed by at least one processing device comprising a processor coupled to a memory. The storage volume illustratively comprises a logical unit of a virtual machine file system, with the one or more designated portions of the logical unit of the virtual machine file system illustratively comprising at least one virtual machine storage drive file of the virtual machine file system. In some embodiments, a bitmap or other data structure is maintained for the storage volume with particular entries in the data structure corresponding to respective ones of the portions.

Abstract: The management and backup of image and video media is automatically performed by evaluating a media file to characterize the content; transforming the media file, as by compressing it, based upon its evaluation and established policies and requirements; and storing the transformed media file with a high resolution in a storage tier having first access characteristics for a first retention period. Following the first retention period, the stored file is re-evaluated and further transformed and stored with lesser resolution in another tier having different access characteristics for a second retention period. Subsequently, the further transformed media file may be transformed again and stored in archive storage.

Abstract: In a decentralized system of nodes configured to provide data protection functionality, wherein at least a subset of the nodes store and share data using content-addresses managed via a distributed hash table in each of the subset of nodes, a given one of the subset of nodes locally stores: a data protection policy to be implemented by the given node; data protected on the given node; and metadata comprising information indicating placement of a given data set on one or more other ones of the subset of nodes. The given node accesses the locally stored metadata to manage protection of the given data set on the one or more other ones of the subset of nodes.

Abstract: Systems and methods for automatically generating a boot sequence. A multiple virtual machine computing environment is analyzed to generate a boot sequence that is used during a recovery operation. The boot sequence may be based on applications and application types running on the virtual machines, a network configuration and network traffic, and on manual boots of virtual machines. The boot sequence prioritizes the order in which the virtual machines are booted in the recovery site.
