Node level recovery for clustered databases

A filtered method of node level recovery at a networked computing system including a node cluster, the method comprising:

• 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 and applying a node-level filter to identify specific rows of backup data to be restored to the new node;
• restoring the specific data rows to the new node;
• identifying new data written by applications, to the existing nodes of the node cluster, during restoration of the new node;
• accessing supplementary back up data and applying the node-level filter to identify supplementary data rows to be restored to the new node;
• and
• restoring the supplementary data rows to the new node.

A non-transitory machine-readable medium including instructions, which when read by a machine, cause the machine to perform operations in a method of node level recovery as a networked computer system including a node cluster, the operations comprising 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 and applying a node-level filter to identify specific rows of backup data to be restored to the new node;
• restoring the specific data rows to the new node;
• identifying new data written by applications, to the existing nodes of the node cluster, during restoration of the new node;
• accessing supplementary back up data and applying the node-level filter to identify supplementary data rows to be restored to the new node;
• and
• restoring the supplementary data rows to the new node.
