  • Patent number: 7941404
    Abstract: Systems and methods are disclosed for providing a federated backup involving the coordination and synchronization of backup and restore operations among a plurality of hosts to ensure data consistency. A master node (backup host) acts as the initiator, coordinator, controller, and possibly as primary console for the entire backup and restore operation. All other worker application hosts and/or worker backup hosts operate as worker nodes and perform various backup and restore steps as directed by the master node. Centralized error handling aborts or recovers the entire backup operation in the event of failure on any one node. In addition, a logical view of the data is provided such that the backup can be managed as one entity, while backing up the data of each node. The backup workload may also be distributed to any other dedicated worker backup hosts (nodes) in order to minimize the impact to the production environment.

  • Patent number: 7716433
    Abstract: Systems and methods for managing a backup process of a database are disclosed. Typically, one or more backup logical unit numbers (LUNs) are identified in a backup management file from one or more available LUNs identified in a universe file are allocated. The backup management file comprises a plurality of data containers, each data container specifying a subset of the one or more backup LUNs capable of backing up a database comprising one or more used database LUNs. One of the plurality of the data containers are allocated for a current backup of the database as indicated in the backup management file. The backup management file is checked and updated as necessary so that the one or more backup LUNs remain available as indicated in the universe file.
