Abstract: Embodiments of the present disclosure relate to methods, devices, and computer readable medium for restoring a file in a virtual machine disk. The method comprises: receiving, from a client, a user's request regarding restoring a file in a virtual machine disk. The method further comprises: determining, based on the request and from a backup disk of the virtual machine disk, files accessible to the user. In addition, the method further comprises providing the client with information related to the files accessible to the user.

Abstract: Embodiments of the present disclosure relate to a method, device and computer readable medium for restoring files. The method described herein comprises: at a client, in response to receiving an instruction for restoring a set of files on a virtual machine from a backup server, obtaining a backup of a set of files from the backup server; transmitting information about the backup and a file downloading application to the virtual machine; causing the file downloading application to be executed on the virtual machine by transmitting an instruction for executing the file downloading application to the virtual machine, such that the virtual machine downloads the backup from the client based on the information about the backup.

Abstract: 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.

Abstract: Embodiments of the present disclosure relate to a method, device, and computer program product for backing up a virtual machine. In one embodiment, the method includes obtaining a first file path in a first operating system installed on a virtual machine, wherein the virtual machine executes on a second operating system. The method further includes determining a second file path in the second operating system corresponding to the first file path based on the first file path and backing up one or more files in the virtual machine based on the second file path.
