Abstract: A method for managing a database system includes obtaining, by a computing node in the database system and from a data protection system, a data protection request for configuring a data protection policy on the database system. In response to obtaining the data protection request: the method further includes making a first determination that the computing node is not configured with a data protection configuration, initiating a deep discovery of the computing node to obtain the data protection configuration, making a second determination that the computing node is not active, identifying a second computing node in the database system that is active, initiating a connection to a database of the database system to detect a successful connection to the database, and after the second determination and based on the successful connection, notifying the data protection system of the second computing node.

Abstract: Automatically updating agents from backup and restore applications is described. A system enables selection of application hosts which meet update requirements, then downloads an update for instances of an application agent corresponding to selected application hosts. The system puts selected application hosts in maintenance mode, which prevents selected application hosts from beginning execution of any operations, until updating selected application hosts is completed. The system initiates update sessions which install update in instances of application agent corresponding to selected application hosts. If update sessions did not fail to install update in any of instances of application agent in cluster of application hosts, then the system stores the updated instances of the application agents in a non-volatile storage.

Abstract: A method for trusted node election. The method includes: identifying a database cluster implemented on a node subset of a plurality of nodes forming a data center; receiving node state from each node in the node subset; and electing, for the database cluster and from the node subset, a trusted node based on the node state from each node in the node subset and a database cluster type of the database cluster.
