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.

Coordinated federated backup of a distributed application environment

Provided are a system, an article of manufacture, and a computer program product, wherein a first set of backup data is stored in a first computational device and a second set of backup data is stored in a second computational device. Metadata corresponding to the first set of backup data is maintained in the second computational device. The first set of backup data is reconciled with the second set of backup data based on the metadata.

Reconciliation of local and remote backup data

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.

Dynamically determining and managing a set of target volumes for snapshot operation

A first set of backup data is stored in a first computational device and a second set of backup data is stored in a second computational device. Metadata corresponding to the first set of backup data is maintained in the second computational device. The first set of backup data is reconciled with the second set of backup data based on the metadata.
