An agent for managing virtual machines includes a persistent storage and a processor. The persistent storage stores backup/restoration policies. The processor identify an end of a backup generation session for the virtual machines; make a first determination that the backup generation was a batch type backup session and, in response to the first determination, performs a batch level continuity analysis of backups generated via the backup generation session to identify a set of backup failures of the backup generation session; performs an unscheduled batch backup generation session based on the identified set of backup failures; and remediates the backup/restoration policies using the identified set of backup failures to ensure backup continuity of all backups associated with each of the virtual machines.
