Abstract: A backup agent for generating backups includes a persistent storage and a backup manager. The persistent storage stores backup/restoration policies. The backup manager obtains production host computing resource characteristics associated with production hosts; performs a computing resource analysis of the production host computing resource characteristics to obtain resource profiles for each of the production hosts; performs an availability analysis of the obtained resource profiles to determine an application-level computing resources distribution for generating the backups; coordinates generating the backups using the application-level computing resource distribution and the backup/restoration policies to obtain the backups; and stores the obtained backups in backup storage.

Abstract: A method for managing virtual machines includes obtaining a restoration request via a first pane of a graphical user interface generated by a graphical user interface manager; in response to obtaining the restoration request: predicting a restoration load for performing the restoration of a virtual machine of the virtual machines; performing a resource availability analysis of the production hosts using the restoration load to obtain a list of production hosts for performing a restoration of the virtual machine; making a first determination that the list specifies at least one production host of the production hosts; and, in response to the first determination: modifying a second pane of the graphical user interface based on the list to obtain a modified second pane; obtaining a user selection of a restoration option displayed in the modified second pane; and restoring the virtual machine using the restoration option and backup/restoration policies.

Abstract: An agent for managing virtual machines includes a persistent storage and an application agent manager. The persistent storage stores backup policies. The application agent manager identifies a new virtual machine instance and, in response to identifying the new virtual machine instance, performs proxy agent based analysis of the new virtual machine instance to generate a data loss threat profile of the new virtual machine instance; remediates the new virtual machine instance by instantiating application agents for the new virtual machine instance based on the data loss threat profile and a portion of the backup policies associated with the new virtual machine instance; updates at least one of the backup policies based on the instantiated application agents; and performs an application backup session for the new virtual machine instance using the instantiated application agents.

Abstract: A computing device for storing backups of virtual machines includes a persistent storage and a backup manager. The persistent storage stores backup policies. The backup manager identifies an end of a backup generation session for a virtual machine of the virtual machines and, in response to identifying the end of the backup generation session, identifies a continuity chain implicated by the backup generation session using the backup policies; performs a membership analysis of the identified continuity chain to identify a continuity state of the continuity chain; makes a first determination that the identified continuity chain is broken based on the identified continuity state; and, in response to the first determination, remediates the continuity chain.

Abstract: A system for identifying and deleting records of hosts includes a local data manager. The local data manager identifies a discovery event associated with the host and a record type of record types, obtains, in response to identifying, all previously discovered records on the host associated with the record type from a host record repository, obtains discovered records associated with the record type and associated with the host, after obtaining all discovered records and previously discovered records, selects a previously discovered record of the previously discovered records, makes a determination that the previously discovered record does not match any discovered records of the discovered records and is not tagged with a soft delete tag or a hard delete tag, and in response to the determination, tags the previously discovered record with a soft delete tag, and notifies a data manager of modifications to the previously discovered records.

Abstract: A backup storage for managing backups of clients includes persistent storage and a backup analyzer. The persistent storage includes the backups, protection policies, and an early deletion schedule. The backup analyzer obtains a request to analyze a protection policy of the protection policies; in response to obtaining the request: obtains backup data information associated with the protection policy; makes a determination, based on the backup data information and the protection policy, that a portion of the backups associated with the protection policies overprotect a client of the clients associated with the protection policy; and modifies the early deletion schedule based on the determination to obtain a modified early deletion schedule.

Abstract: An agent for managing backup generation for virtual machines includes a persistent storage stores backup policies and a backup manager that obtains request for generating a backup for a first virtual machine of the virtual machines and, in response to obtaining the request, generates a backup load prediction for generating the backup; performs a resource availability analysis of a host computing device hosting the first virtual machine to determine computing resources availability for generating the backup; makes a first determination, using the backup load prediction and the computing resource availability, that the host computing device has insufficient resources for generating the backup; and, in response to the first determination, performs a backup type analysis on existing backups associated with the first virtual machine to obtain at least one updated backup policy; and generates a reduced-resource cost backup for the virtual machine using at least one of the updated backup policies.
