Abstract: Failover of a Docker container between nodes of a cluster is orchestrated to enable the Docker container's data to be made available across all nodes of the cluster. Using this orchestration system, if a second cluster node is selected to be used to bring up a Docker container, the orchestration system coordinates destroying the previous Docker volumes on the first cluster node, unmounting a physical device containing the application data from the first cluster node's virtual filesystem, remounting the physical device containing the application data in the virtual filesystem of the second cluster node, creating a Docker volume referencing the application data on the second cluster node, and using the Docker volume to start a new instance of the Docker container on the second cluster node. This enables the Docker container to be started on any node of a cluster and have the application data available as a local filesystem.

Abstract: Disclosed herein are system, method, and computer program product embodiments for automatically failing over all services operating on a primary region to a secondary region upon detection or notification of a fault in the primary region. When a fault exists on the primary region, the method traverses each cluster containing services operating on the primary region and prepares an input file including a list of service names identifying each service operating on the primary region. Referencing the input file, the method fails over each service from the primary region to the secondary region by modifying a service weight corresponding to each service. This failover process of services may be done simultaneously with failing over any databases corresponding to the failed-over services from the primary region to the secondary region. The method may also introduce a sleep time after modifying each service weight to avoid any potential throttling issues.

Abstract: In various embodiments, techniques can be provided to address debug efficiency for failures found on an operational system. The techniques can utilize a real-time trigger to notify a memory device to dump an error log to timely capture all needed information. In response to detecting one or more error conditions associated with the memory device, a system that interfaces with the memory device can generate a trigger signal to the memory device. In response to identifying the trigger signal, the memory device can dump an error log of the memory device to a memory component in the memory device. The error log can later be retrieved from the memory component for failure analysis.

Abstract: A method and system for enabling incremental backup operations targeting bare-metal recovery and system-state recovery data and metadata. These aforementioned forms of recovery focus on the protection of computing system state, including operating system binaries and configuration, as well as the data, metadata, and/or configuration of software application(s) installed on said computing system(s). Further, the data and/or metadata reflected in said computing system state often remains unchanged unless operating system and/or software application component(s) or feature(s) is/are uninstalled, installed, and/or upgraded. Existing solutions protecting said data and/or metadata tend to only support full backup operations, which are time and storage space inefficient. Ideally, incremental backup operations targeting said data and/or metadata should be provided.

Abstract: Techniques for data management are described. A monotonically increasing time source that indicates an elapsed time since a reference event may be activated. Multiple snapshots of a computing object may be generated in accordance with a schedule for backing up the computing object, where the schedule may include a retention duration for retaining snapshots. Based on generating the snapshots, timestamps for the snapshots may be stored, where the timestamps may indicate respective values of the monotonically increasing time source.

Also, a snapshot of the snapshots may be expired based on a timestamp of the snapshot corresponding to a value of the monotonically increasing time source that is less than the reference value.
