This is achieved by running a pre-backup step, either periodically or prior to the reception of a backup request, to determine the preferred node for backup. Once the backup request is received, the cluster manager queries the preferred node, if the preferred node is still the best data node to perform the backup, then that data node performs the backup. If, however, the preferred data node no-longer is the best data node for performing the backup, the current preferred data node will signal the cluster manager with an alternative data node that is best data node to perform the backup and the cluster manager will have that alternative data node perform the backup. ## Claims ### Claim 1 A method for performing a backup in a cluster environment comprising of a plurality of data nodes, the method comprising: receiving a backup request (BR) to backup at least one asset associated with at least one of the data nodes in the cluster environment, wherein a cluster manager (CM) receives the BR from a user via a client over a communication network (CN), wherein the CM and the client are operably connected to each other over the CN, wherein the CN implements a network protocol, wherein, before sending the BR, the user determines the at least one asset to be protected and a preferred data node that needs to perform the BR, and wherein the BR specifies the at least one asset and the preferred data node, wherein each of the data nodes is a computing device that comprises at least integrated circuitry that performs computer implemented services for the user;
