Abstract: Embodiments disclosed herein provide systems, methods, and computer readable media for data lineage based multi-data store recovery. In a particular embodiment, a method provides identifying first data in a first table of a plurality of tables stored in a plurality of data stores and restoring the first data to a first correct version of the first data in a prior version of the first table. The method further provides identifying a second table of the plurality of tables that descends from the first table and includes second descendent data that stems from the first data. The method also provides restoring the second descendent data to a second correct version of the second descendent data in a prior version of the second table.

Abstract: A object data backup and restore method and system include receiving a request to restore a target object to a first point-in-time version; identifying a first snapshot of the cluster corresponding to the first point-in-time version; generating a second snapshot of the cluster upon receiving the request to restore the target object; determining data changes associated with the target object based on the first snapshot and second snapshot; scanning all objects associated with the cluster to determine one or more additional objects that are affected by restoring the target object due to object dependencies defined by a cluster configuration; generating a relationship graph for the one or more additional objects and the target object; and restoring the target object based on the data changes, the first snapshot and the relationship graph.

Abstract: Described herein is a system that restores a database by processing a portion of the database. The system restores the database to a previous state at a particular time by reverting data entries that have changed since the time to their initial values before the change. Data entries that have changed after the restore time are identified. For the data entries that have changed after the restore time, their initial values before the change are determined from various sources. The system determines a database version that is created most recently before the restore time. The system additionally identifies changes to the database between the restore time and when the database version is created. The initial values can be determined from either the database version or the changes made to the database between the restore time and when the database version is created.

Abstract: A method of restoring version data stored across two or more cloud environments is provided. An example method includes accessing, in a second cloud environment, first metadata describing a first data version, the first data version including first data items and first metadata, wherein at least the first data items are stored in a first cloud environment and the first metadata is stored in a third cloud environment. In response to an instruction received in the second cloud environment, the first data items are restored to the second cloud environment using the first metadata.

Abstract: Systems and methods for node consistency in a clustered database are described. The system automatically identifies an addition of a first node to a clustered database on a source storage platform. The system initializes the first node on the source storage platform communicating a first node agent to the first node. The first node agent is configured to execute on the first node to extract the operation log at the source storage platform and stream the operation log to the secondary storage platform. The system versions a first version of the clustered database. The versioning of the first version including not storing a version of the operation log associated with the first node at the secondary storage platform responsive to identifying, during the first interval of time, the synchronizing of the operation log at the first node having not been synchronized, in a prior version of the clustered database, with the operation log at the storage platform.

Abstract: Embodiments disclosed herein provide systems, methods, and computer readable media to enhance the organization, storage, and retrieval of data. In a particular embodiment, a method provides storing a plurality of incremental data versions in a data repository and maintaining first time information for data items in each of the incremental data versions. The method further provides identifying a first data version of the plurality of incremental data versions and writing data in the data repository to create a second data version based the first data version. The method then provides second time information associated with the creation of the second data and creation of the first data version.
