Techniques for warm cloning of computing nodes are provided. A request to clone a first computing node is received. Upon determining that a first transaction of a plurality of transactions is ongoing, a first moment in time when data associated with the first transaction was coherent on the first computing node is identified. Tracking data related to the first transaction is collected, beginning at the first moment in time. Further, a first storage associated with the first computing node is copied to a second storage associated with a second computing node, where the first transaction continues during the copying. The tracking data related to the first transaction is then transmitted to the second computing node.
