Abstract: Techniques are described herein that are capable of selecting checkpoints of a database job. For instance, at compile time, temporal indicators associated with the query plans of the database job are determined. Each temporal indicator indicates first and second subsets of stages of the respective query plan. Values of attributes of each stage in at least each first subset are predicted using a machine learning technique. At the compile time, candidate stage(s) for each query plan are identified based on the respective candidate stage being a child of stage(s) in the corresponding second subset or not being a child of another stage in the respective query plan. The candidate stage(s) for each query plan are selectively chosen as respective checkpoint(s) based on whether the values of the attributes of each stage in at least the first subset of the stages of the respective query plan satisfy one or more criteria.

Abstract: The described technology is generally directed towards distributing data fragments and coding fragments of a protection group among storage entities (e.g., nodes or disks) based on affinity levels (e.g., maintained in an affinity matrix) that represent dependency relationships between the storage entities with respect to storing protection groups. The technology operates to distribute a protection group's components such that the affinity level between any pair of storage entities is approximately the same as any other pair. In the event of a storage entity failure, as a result of the affinity-based distribution of the protection group components needed for data recovery, a larger number of the other storage entities can be involved in the data recovery (relative to the number likely involved without affinity-based distribution). This tends to assure a better load balance and faster data recovery.

Abstract: The disclosed systems and methods enable an application to start operating and servicing users soon after and during the course of its backup data being restored, no matter how long the restore may take.

Any primary data generated by the application during “instant application recovery” is not only retained, but is efficiently updated into restored data. An enhanced data agent and an associated pseudo-storage-device driver, which execute on the same client computing device as the application, enable the application to operate substantially concurrently with a full restore of backed up data.
