Method, device and computer program product for data backup including determining a hardware configuration allocated to a proxy virtual machine based on a workload of a backup job
Methods, devices and computer program products for data backup are disclosed. The method includes receiving, from a destination node, a workload of a backup job, the workload being determined by the destination node in response to a request for the backup job from a source node, and determining a hardware configuration to be allocated to a proxy virtual machine deployed in a plurality of virtual machines on the source node based on the workload, the proxy virtual machine including a backup application for performing data backup for the plurality of virtual machines. The method further includes transmitting an indication of the hardware configuration to the proxy virtual machine to enable the backup application to perform the backup job using the hardware configuration. The workload may comprise a data change rate of the source node and a backup rate of the proxy virtual machine that are predicted based on history data stored at the destination node. The history data may include backup times required by a unit workload for previous backups. An indication of an allowed number of concurrent backups for a backup job may be transmitted to the proxy virtual machine.
