System for implementing intermediate storage by virtual tape drive and method thereof

Abstract

A system and method for realizing intermediate storage by a virtual tape drive, wherein the system includes a user interface module, a mirror image module, a storage module and a management module; the method comprises the following steps: according to the data format provided by the real tape drive, The tape image is stored in a large-capacity random storage device. First, the user interface module receives the tape model and data capacity of the virtual tape drive set by the user, and then receives the user data. The mirror module creates a tape according to the model, data capacity and the user data. Image file, the storage module stores the tape image file in a large-capacity random storage device, and realizes the operation of the data through the management module, which can not only solve the problem of insufficient backup space during data backup, but also improve the speed of data retrieval.

Description

technical field [0001] The invention relates to a system and method for realizing intermediate storage, in particular to a system and method for realizing intermediate storage by a virtual tape drive. Background technique [0002] With the in-depth development of informatization construction, data security has become more and more important. In order to ensure data security, the use of storage backup devices is essential. The storage and processing of massive amounts of information has posed a great challenge to previous computer technologies, and has also formed a huge industry. For the storage field, the storage hardware of the PC itself is far from being able to meet the needs of consumers. When the importance of data backup is recognized by more and more users, many new technologies and products appear in the personal storage market. As a safe, reliable, easy-to-use and effective investment backup method - tape backup, of course, has become the focus of users' attentio...

AI Technical Summary

Problems solved by technology

However, the existing tape drives usually have a slow data retrieval speed. During data recovery, unnecessary time loss is often caused due to the inability to retrieve the data that needs to be restored in time, and low-file tape drives generally do not have the function of automatically changing tapes. When backing up a large amount of data, because the administrator does not know whether or when to change the tape, the long waiting time causes great inconvenience to the backup operation, especially during network backup, if the network speed is lower than the backup speed time, it will cause a waste of tape space

Although some intermediate storage devices can improve the speed of data retrieval, because the data in the intermediate storage devices is stored in the original data format, it causes inconvenience to data backup and increases the complexity of data management.

Although the high-speed tape drive with automatic tape change function can solve the manual operation difficulty of tape change, it does not fundamentally solve the problem of data retrieval speed, and also wastes tape space due to network speed during network backup.

Moreover, the common feature of the intermediate storage device and the high-speed tape drive with the automatic tape change function is that it is expensive, and it is not suitable for the application of small and medium-sized enterprises.
