Embodiments of the present disclosure relate to a method for providing log information, an electronic device, and a computer program product. A method for providing log information includes: determining a first set of semantic segments including fault information from multiple semantic segments into which a set of log files of a target system is divided; extracting key information specific to the target system from the first set of semantic segments; determining, based on the extracted key information, an application scenario involved in the fault information and at least one log file related to the application scenario in the set of log files; determining a second set of semantic segments including the key information from multiple semantic segments into which the at least one log file is divided; and providing the first set of semantic segments and the second set of semantic segments by highlighting the fault information and the key information in the first set of semantic segments and the second set of semantic segments. The embodiments of the present disclosure contribute to improving the efficiency of a user in locating the cause of a system fault, thereby improving user satisfaction.

Method, electronic device, and computer program product for extracting fault information from log files

A method, a device and a computer program product for managing data backup are provided. The method comprises: obtaining a first set of performance parameters of a backup client prior to performing a data backup, the backup client being configured to transmit data to a backup server for backup and record information about the data in a cache to avoid duplicate data being transmitted to the backup server; determining, from a plurality of sets of historical performance parameters collected during multiple historical data backups performed by the backup client, at least one set of historical performance parameters similar to the first set of performance parameters; determining, from the at least one set of historical performance parameters, a set of historical performance parameters indicating the best performance; and adjusting, based on the set of historical performance parameters, an available capacity of the cache to be used in the data backup.

Method, device and computer program product for managing data backup

Embodiments of the present disclosure provide a method, a device and a computer program product for managing data replication. According to example implementations of the present disclosure, a replication policy model associated with data replication of a source device can be obtained, which is determined based on historical status information of the source device and a historical replication policy corresponding to the historical status information; current status information of the source device is determined, wherein the current status information indicates status information associated with pending data replication of the source device; and a target replication policy is determined based on the replication policy model and the current status information, which indicates a replication policy to be applied for performing the pending data replication. Therefore, the replication policy can be adjusted automatically based on the status of the source device, enabling a more efficient and intelligent data replication of the source device.

Method, device and computer program product for managing data replication

Embodiments of the present disclosure provide a method, a system and a computer readable storage medium for data backup and restoration in a cluster system. The method comprises obtaining performance data of the nodes, the performance data being collected periodically by the backup and restore proxy modules; predicting workloads of the nodes based on the performance data; selecting, based on the predicted workloads, a backup node from the nodes, to take over a data backup and restore task from a working node which is currently in charge of the data backup and restore task.
