Abstract: A method and system for shared workload anomaly detection across multiple hosts based on bare-metal recovery and/or system-state recovery data and metadata. Since at least said bare-metal recovery and/or system-state recovery metadata has information about each workload operating on one or many host(s), comparing said metadata across any set of hosts could provide the pattern of data being generated there-across. Further, other metadata generated by any shared workload instance(s), operating on a set of hosts, should be consistent across the set of hosts. Should a shared workload instance on one or more hosts generate metadata not sync with metadata generated from a baseline shared workload instance, such discrepancies could be a sign of unwanted anomalies that may warrant further analyses, alerts, etc.

Abstract: Described is a system for cloud-based processing of backup data for storage onto various types of object storage systems. A specialized cloud-based component (e.g. proxy server) may act as an intermediary when backing up data from a client system to an object storage. For example, the cloud-based component may be provided as part of backup service that operates in conjunction with a client system. Accordingly, the system may allow different clients of a backup service to efficiently and seamlessly interact with the different third-party object storage providers via a single cloud-based component. To provide such object-storage-agnostic functionality, the cloud-based component may include a function library that includes object-storage-specific functions. For example, the cloud-based component may invoke a specific set of operations that interact with a storage API provided by a particular object storage provider.
