Abstract: A remote agent, for providing data protection services to virtual machines, includes persistent storage and a backup manager. The persistent storage is for storing a resource allocation calendar and lifecycle policies associated with the virtual machines. The backup manager obtains a virtual machine data package from a virtual machine of the virtual machines; identifies a computational load change point based on the lifecycle policies; predicts a magnitude of a computational load during a period of time demarcated by the computational load change point using, at least in part, the virtual machine data package; updates the resource allocation calendar to obtain an updated resource allocation calendar, the updating is based on: the identified computational load change point, and the magnitude of the computational load during the period of time; and generates a backup for the virtual machine using the updated resource allocation calendar.

Abstract: A remote agent for providing data protection services includes persistent storage and a backup manager. The persistent storage stores lifecycle policies. The backup manager updates an asset catalog using an asset map associated with a virtual machine; generates a lifecycle policy of the lifecycle policies using the asset catalog; and generates a backup for the virtual machine using the lifecycle policy. The lifecycle policy prioritizes generating the backup for the virtual machine over generating a second backup for a second virtual machine.

The production agent obtains backup generation requests for the virtual machines; in response to obtaining the backup generation requests, generates the backup groupings queue based on the backup generation requests; identifies a maximum parallelism of the production host based on resources utilized by a portion of the virtual machines specified by the backup groupings queue; consolidates the backup groupings queue to generate the backup process stack; and generates backups for virtual machines specified by the backup process stack in parallel based on the maximum parallelism.

Abstract: A method and system for intelligently resolving failures recurring in information technology (IT) environments. Specifically, the method and system disclosed herein may be directed to the resolution of persistently-occurring failures observed in data backup and/or data recovery operations. Further, resolution of any given persistently-occurring failure may entail the identification of zero, one, or more solutions (e.g., patches and/or other instructions) based on the analyses of failure-related information and host-related configuration information using machine learning and/or artificial intelligence paradigms. In cases where zero solutions are identified, the conventional and manual investigative route by way of support ticketing may be pursued.
