Embodiments of the present disclosure provide a method, an electronic device, and a computer program product for tracing information. The method includes: receiving an information acquisition request from a work container, the information acquisition request comprising information about a workload of the work container; determining, based on the information about the workload, a group to which the workload belongs; determining tracing information corresponding to the group, the tracing information being used for associating a log of the workload with logs of related workloads of the workload; and sending the tracing information to the work container. With the method according to embodiments of the present disclosure, the work container does not need to save a tracing context for each workload. This can save storage space in the work container, even without taking up storage space in the work container.

Embodiments of the present disclosure relate to a method, a device, and a computer program product for document transmission. The method includes: selecting a portion to be encoded from a document that comprises structured portions, wherein each of the structured portions comprises an identifier and data associated with the identifier; acquiring at least one structured portion of the portion to be encoded; performing the following operations for a corresponding structured portion of the at least one structured portion to encode the document: generating a hash value of data of the corresponding structured portion; determining whether a hash value repository comprises the hash value; and replacing, based on a determination that the hash value repository comprises the hash value, the data of the corresponding structured portion in the document with the hash value; and sending the encoded document to a receiver. This solution can reduce the bandwidth consumption of transmitting a document including structured data while ensuring that a receiver obtains required information, as well as potentially saving the storage space required by the receiver to store the received document.

Method, device, and computer program product for document transmission

Embodiments of the present disclosure provide a method, an electronic device, and a computer program product for grouping objects in a data management system. The method includes: detecting operation parameters of at least two of a plurality of objects in a data management system, and determining a rate of correlation between the at least two objects based on the detected operation parameters, wherein the rate of correlation indicates a degree of correlation between the at least two objects. The method further includes: comparing the determined rate of correlation with a predetermined threshold, and determining, based on the comparison of the determined rate of correlation with the predetermined threshold, grouping of the at least two objects. With this method, objects with a high degree of correlation are logically grouped together, so that a user can manage objects in batches in an efficient manner during object management, thus improving the system performance. In particular, data consistency can be maximized in the process of data protection and restoration.

Method and electronic device for grouping objects in data management system

Embodiments of the present disclosure relate to a method, a device and a computer program product for recovering data. The method comprises in response to receiving a request to recover data from a backup node to a source node, determining a plurality of candidate backup nodes having copies of the data; determining respective performance indicators of the plurality of candidate backup nodes; and determining, from the plurality of candidate backup nodes, the backup node for recovering the data to the source node based on the respective performance indicators of the plurality of candidate backup nodes.

Method, apparatus and computer program product for recovering data

The present disclosure relates to a method, an electronic device, and a computer program product for recovering data. For example, a method for recovering data is provided. The method may comprise acquiring metadata corresponding to to-be-recovered target data, the metadata comprising at least a first part of metadata corresponding to a first set of data blocks and a second part of metadata corresponding to a second set of data blocks. The method may further comprise acquiring, based on the first part of metadata, the first set of data blocks from a first backup storage device in a plurality of backup storage devices that store the target data. The method may further comprise acquiring, based on the second part of metadata, the second set of data blocks from a second backup storage device in the plurality of backup storage devices. In addition, the method may further comprise recovering the target data based on at least the first set of data blocks and the second set of data blocks. As such, the utilization of the backup storage devices can be improved and the time for data recovery can be shortened.

Method, electronic device, and computer program product for recovering data

Embodiments of the present disclosure relate to a method for upgrading a system, an electronic device, and a computer program product. A method for upgrading a system includes determining a first group of modules to be upgraded in a first stage and a second group of modules to be upgraded in a second stage after the first stage from a plurality of modules of the system. The method further includes upgrading the first group of modules in the first stage and causing the upgraded first group of modules to provide a corresponding service. The method further includes upgrading the second group of modules in the second stage while the upgraded first group of modules is providing the corresponding service.

Method for upgrading system, electronic device, and computer program product

A method, electronic device and computer program product for categorizing a document that includes determining a key words associated with a document category and corresponding weight. The method also includes determining a score of the document with respect to the key word at least based on frequencies of the key word appearing in a field of the document and the weight and determining that the document is in the document category in response to the score of the document being higher than a threshold.
