1results about How to "Reduce migration time" patented technology

The application provides a data migration method and device, electronic equipment, a storage medium and a program product, relates to the technical field of data storage, and the method comprises the following steps: firstly, monitoring a file list in an object storage service of source data, determining an incremental file index, and the file list comprising file identifiers of files stored by the object storage service; the incremental file index comprising file identifiers of incremental files in the file list; then, reading incremental data corresponding to the file identifiers of the incremental files from a source data address, and writing the incremental data into a target data address. In the embodiment, the incremental data can be quickly identified and migrated to the target data address by monitoring the file list, the data migration time is reduced, and the high timeliness requirement of data migration is met.
