Abstract

The invention discloses a data transfer method and a data transfer system, which aim to solve the problems of complexity, low efficiency, high cost and difficulties in the realization of massive data transfer of the conventional data transfer operations. The method comprises the following steps of: reading source data to be transferred from a magnetic tape; detecting a source data magnetic tape format; after the magnetic tape format is identified, performing data conversion and processing according to a magnetic tape format structure to extract valid data; detecting a data file format, wherein the file format refers to the storage format of data recovered to a disk; and after the data file format is identified, converting and processing records and fields in the data, simultaneously adding tags among the records and the fields according to a conversion strategy, generating an intermediate file, and packing and outputting the generated intermediate file into a target storage unit. The method and the system are used for the occasions of transferring the source data, exceeding a certain time limit, in the magnetic tape onto the new target storage unit.

Description

technical field [0001] The invention relates to the field of computer system data processing, in particular to a tape data migration method and system. Background technique [0002] In computer application systems in many industries such as finance and insurance, there are a large number of historical data that are exported to magnetic tapes, magnetic disks, optical discs or any storage unit known in the art (hereinafter referred to as magnetic tapes). Precious information materials and digital assets need to be preserved and utilized for a long time. However, on the one hand, because the tape has a certain life cycle, as the storage time increases, the tape will gradually age. After a certain period, the data on the tape may be damaged or lost; on the other hand, with the computer hardware and software technology With the development and upgrading of the original backup system and platform (such as database system, business system, etc.) use below. Therefore, it is neces...
