Problems solved by technology

[0007] At present, the tape-based data archiving and backup method in large-scale networks is only suitable for stable scenarios where the archived data is relatively planned. For other scenarios such as the amount of archived data is relatively random and the data is frequently retrieved, more tapes will be consumed, and it may also be Causes idle waste of storage space in the tape and reduces storage efficiency

Embodiment Construction

[0036] A tape-based data archiving and backup method and system according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] In the tape library management in the media field, it generally includes the management of the entire program data, the management of traditional analog tapes and data stream tapes entering and leaving the library, the management of program tapes and blank tapes, program exchange, program purchase and information feedback, etc. Provide efficient, stable and automatic management for the comprehensive business of TV stations, thereby optimizing the workflow of the tape library and improving office efficiency and management level.

[0038] Typically the lifespan of stored data on LTO tape is quoted as 30 years, although this number is somewhat variable, and the number of years quoted by tape manufacturers is based on ideal storage conditions: a constant temperature of about 70 deg...

Abstract

An embodiment of the invention discloses a method for archiving and backing up tape-based data and a system thereof, and belongs to the field of data storage. The method includes the steps of reading a remaining period of a current tape from a tape library, predicting an access frequency of a matching file based on the remaining period; according to the access frequency of the file, selecting a data file of files to be archived and backed up, archiving and backing up the data file to the current tape of a tape unit; and in the process of archiving and backing up, monitoring the state parameter of the current tape and prompting if a set threshold is exceeded. Through introduction of control and storage in the process of reading and writing the tape and integration of tape factors such as loading and unloading times, complete storage times and data access time, the method for archiving and backing up tape-based data and the system are capable of balancing the use of tapes, timely prompting the tape replacement, and being applicable to a scene consumed a plurality of tapes due to random amount of archiving data and frequency of backup data, and the like. Besides, waste of storage space of the tape is avoided, storage resource is reasonably allocated, execution procedures are optimized, and storage efficiency is improved.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a tape-based data archiving and backup method and system. Background technique [0002] Tape is an important part of the storage system and is usually used for archiving and backup of large-scale data. In the centralized network archiving and backup system, each tape is automatically disassembled and reloaded in the tape library by a robotic arm, and intelligent recovery, real-time monitoring and statistics can be realized with the support of management software. [0003] Tape media has its own life cycle, and when the tape media is approaching this period, it needs to be replaced. For example, the lifespan of data stored on an LTO tape is 15 to 30 years; the number of times the tape is loaded / unloaded is 5000 times; 260 times of complete storage (one complete storage means that the tape is filled with data). [0004] Due to the frequent removal of tapes, tape drive components are p...
