Abstract
An example networked computing system comprises a node cluster; a database; at least one processor configured by instructions to perform operations in a method of node level recovery, the method comprising operations including at least: identifying a failed node among existing nodes in the node cluster; identifying and initiating a replacement node as a new node for the node cluster; accessing at the database a logical backup of the node cluster; retrieving logical backup data of the node cluster from the logical backup and applying a node level filter to identify rows of backup data associated with the failed node; and restoring the data rows identified by the node level filter to the new node.
