Problems solved by technology

[0011] For this reason, the data storage method, device and system of the present invention solve the problem that the dirty data record file needs to grow during the download process by creating a dirty data record file of a predetermined size in the disk space and keeping its size constant throughout the download process , thereby avoiding the failure of writing dirty data record files
Further, the present invention solves the problem that the dirty data cannot be written back to the data file by recursively prioritizing the dirty data, thereby avoiding the unstable state that the dirty data only exists in the memory

Embodiment Construction

[0038] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0039] As mentioned above, in order to effectively avoid the inconsistency of dirty data during the data download process and ensure that the data files after storage can be effectively opened, the present invention uses recursive priority writing of dirty data and pre-allocation of disk space for dirty data record files and continuous There are solutions to solve the problems of data file writing failure and dirty data record file writing f...

Abstract

The invention discloses a data storage method, a data storage device, a data storage system, and portable electronic equipment. The method comprises the steps of building a dirty data record file with a predetermined size; determining a target storage position of queue head data of a queue to be written in the data file; inserting a dirty data record corresponding to dirty data into the queue to be written and using as the new queue head data in the case of determining that the target storage position is occupied by the dirty data; and updating the dirty data record file. By using the method, device and system provided by the invention the problem that the data file and the dirty data record file are failed to write in due to insufficient magnetic disk space is solved, so that inconsistency of the dirty data is avoided, and thus a failure rate of writing data is reduced.

Description

technical field [0001] The present invention generally relates to the technical field of data storage, in particular to a data storage method, device and system for segment writing, and a portable electronic device. Background technique [0002] At present, the most common file download methods are concurrent multi-segment and breakpoint resume, that is, when downloading, the file is divided into multiple segments of data, and each segment of data is downloaded with an independent thread, and multiple download threads are running at the same time. When the download task is suspended at a certain point in time, the download position at this time is the breakpoint. When the unfinished download task starts again, the transmission will continue from this breakpoint. Concurrent multi-segment and breakpoint resuming can avoid repeated downloads and make full use of network bandwidth, thereby increasing download speed. [0003] However, with the popularization of portable mobile d...
