Abstract: According to example embodiments of the present disclosure, provided is a method, device and computer program product for backing up data. The method comprises: determining a first number of data streams for sending target data; causing the target data to be sent to a buffer via the first number of data streams; determining a second number of data streams for sending the target data from the buffer to a server based on a transmission parameter associated with transmission of the target data to the buffer and a capability of the server for receiving data from the buffer; and causing the target data to be sent from the buffer to the server via the second number of data streams. Thereby, the present solution can improve the performance of sending data in a backup client.

Abstract: Embodiments of the present disclosure provide a storage management method, an electronic device, and a computer program product. The method includes determining at least one count corresponding to at least one data segment of a file in a file set, the file set being stored in a local storage device, and the at least one count indicating the number of occurrences of the at least one data segment in the file set. The method further includes determining a deduplication ratio of the file based on the at least one count, the deduplication ratio indicating an overlapping level of the file with other files in the file set. The method further includes migrating the file from the local storage device to a remote storage device according to a determination that the deduplication ratio of the file is lower than a threshold.

Abstract: Embodiments of this disclosure relate to a method, a device and a computer program product for data protection. The method comprises determining objects selected by a user in a set of objects, and automatically generating one or more corresponding filtering conditions according to the objects selected by the user. The method further comprises automatically setting a predetermined protection policy for objects meeting the filtering conditions in the set of objects. In the embodiments of this disclosure, corresponding filtering conditions are automatically generated according to some protected objects selected by a user to form a dynamic filter, without manually setting the filtering conditions by the user, thereby improving the user experience of a data protection system.

Abstract: A method and apparatus for maintaining a participation level for a plurality of communication devices assigned to a task group. A server is communicatively coupled to the plurality of communication devices assigned to the task group and defines a minimum quantity of communication devices to be assigned an active executor role for the task group. Communication devices that are assigned the active executor role are locked to the active executor role for the task group when the quantity of communication devices that are currently assigned the active executor role does not exceed the minimum quantity of communication devices to be assigned the active executor role for the task group.
