Node level recovery for clustered databases

A 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 identifying 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;
• iteratively accessing supplementary back up data to identify supplementary data rows to he restored to the new node;
• and
• iteratively restoring the supplementary data rows to the new node until the new node is synchronized with the existing nodes in the node cluster.

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 at a networked computing 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 identifying 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;
• iteratively accessing supplementary back up data to identify supplementary rows to be restored to the new node;
• and
• iteratively restoring the supplementary data rows to the new node until the new node is synchronized with the existing nodes in the node cluster.
