    • 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.
    • 公开了用于提供涉及多个主机之间的备份和恢复操作的协调和同步的联合备份以确保数据一致性的系统和方法。 主节点(备份主机)充当启动器,协调器,控制器,并可能作为整个备份和还原操作的主控制台。 所有其他工作应用程序主机和/或工作者备份主机作为工作程序节点运行,并按照主节点的指示执行各种备份和还原步骤。 集中式错误处理在任何一个节点发生故障时中止或恢复整个备份操作。 此外,提供数据的逻辑视图,使得备份可以作为一个实体来管理,同时备份每个节点的数据。 备份工作负载也可以分发到任何其他专用工作人员备份主机(节点),以便最小化对生产环境的影响。
