Abstract

The invention discloses a data backup method and device. The data backup method comprises the following steps: visualizing one part of hard disk in a server into a virtual tape library, wherein the left hard disks are real physical hard disks; classifying data which needs to be backuped, wherein the data comprises the data which needs to be backuped for a long time and the data which needs to be backuped for a short time; backuping the data which needs to be backuped to the virtual tape library; and transferring the data which needs to be backuped for a long time into the real physical hard disks from the virtual tape library to be stored. The technical scheme firstly backups the data which needs to be backuped to the virtual tape library, so that the technical scheme is high in speed and efficiency, the data which needs to be backuped is classified, the data which needs to be backuped for a long time is transferred to the real physical hard disks, and transferring work can be carried out when the server is idle. Compared with the prior art, the data backup method and device is more scientific and can hierarchically store the data in a targeted way.

Description

technical field

[0001] The invention relates to the technical field of data storage, in particular to a backup method and system. Background technique

[0002] In the prior art, it takes a long time and low efficiency to store the data to be backed up on a real physical hard disk. How to improve the efficiency of data backup storage is a technical problem that needs to be solved at present. Contents of the invention

[0003] In order to solve the above problems, the present invention provides a data backup method, said method comprising:

[0004] Virtualize part of the hard disk in the server as a virtual tape library, and the remaining hard disks are real physical hard disks;

[0005] Classifying the data that needs to be backed up, including data that needs long-term backup and data that needs short-term backup;

[0006] Back up the data to be backed up to the virtual tape library;

[0007] The data requiring long-term backup is migrated from the virtual tape library...
