  • System and method for critical virtual machine protection
    Patent number: 11030057
    Abstract: A backup agent for facilitating restorations of virtual machines includes a persistent storage and a backup/restoration policy updater. The persistent storage stores backup/restoration policies. The backup/restoration policy updater identifies a change of a label associated with data of a production host and, in response to identifying change in the label, identifies a virtual machine of the virtual machines associated with the data; performs a threat analysis of the identified virtual machine to determine a new security policy for the identified virtual machine; and updates a policy of the backup/restoration policies associated with the identified virtual machine based on the identified new security policy.

  • SYSTEM AND METHOD FOR STORAGE UNAVAILABILITY TOLERANT BACKUP
    Publication number: 20210117278
    Abstract: Systems, devices, and methods for reducing the impact of temporary unavailability of storages in a backup storage system. The system may store different types of backups depending on the availability storages. The first type of backup, which may rely on a previous backup stored in a first storage that is available for restoration purposes, may be stored on the first storage. When the first storage becomes temporarily unavailable, a second type of backup may be stored in a second storage that is available that requires a previous backup stored in the temporarily unavailable first storage for restoration purposes. The second type of backup may be chained to the previous backup stored in the temporarily unavailable storage. The second type of backup may be converted to the first type of backup when the first storage becomes available again in a computationally efficient manner.

  • METHOD AND SYSTEM FOR EFFICIENT RESOURCE USAGE THROUGH INTELLIGENT REPORTING
    Publication number: 20210026742
    Abstract: A method and system for efficient resource usage through intelligent reporting. Specifically, the method and system disclosed herein entail implementing resource-efficient messaging between computing systems engaging in centralized restore operations. A centralized restore operation may refer to the initiation and management of the restoration of data on a remote computing system from a local computing system. Further, conventional management of a centralized restore operation necessitates frequent reporting on the state of the restoration process, which may inefficiently expend memory and network resources.
