Embodiment Construction

[0028] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0029] Such as figure 1 Shown, a kind of LTFS-based video and audio archiving storage and calling method, it comprises video and audio archiving method and video and audio calling method, described video and audio archiving method comprises following sub-steps:

[0030] S11: Access the tape auxiliary storage, and obtain the specific index position of the tape;

[0031] S12: compare the virtual channel VCI information in the tape auxiliary storage, and obtain the storage partition of the latest index file Index;

[0032] S13: access the VCI information in the tape auxiliary storage, and locate the position of the latest Index in the auxiliary storage in the disk storage partition;

[0033] S14: The hard disk accesses and parses the archive...

Abstract

The invention discloses an LTFS-based video and audio archiving and calling method, which includes a video and audio archiving method and a video and audio calling method. When archiving, the tape auxiliary storage is first accessed to obtain the Index in the tape auxiliary storage partition, and the tape is stored to When writing data, first parse the file to get the Index, and then store the Index and the source file on the tape using the dual-threaded multi-cache mechanism. When calling, access the tape auxiliary storage, obtain the necessary information of the file in the Index in the tape auxiliary storage, then calculate the data of the file, obtain the information of the required data, and synthesize the dotted file. The beneficial effects of the present invention are: it can meet the long-term archiving and relocation of large-scale mass video and audio, realize the self-description of the tape, know the content stored on the tape without an additional storage system, and the entire tape is self-contained and has high security A video and audio archiving storage and recall method with high performance and availability.

Description

technical field [0001] The invention relates to the field of magnetic storage archiving, in particular to an LTFS-based video and audio archiving storage and calling method. Background technique [0002] Magnetic tape is a strip-shaped material with a magnetic layer for recording sound, image, digital or other signals. It is the largest and most widely used magnetic recording material. It is usually formed by coating a layer of granular magnetic material on a plastic film base (support) or by evaporating and depositing a layer of magnetic oxide or alloy film. [0003] LTFS is the abbreviation of Linear Tape File System, which is recognized as a technology that will revive the tape application. Through the file tree directory, this technology allows users to search the information on the tape for the first time, and the process of searching tape is the same as that of disk storage. Users can freely drag and drop files from an LTFS-formatted tape, which makes it possible to ...
